How to enable AV mode without a remote control on an old TV?

Setting up channels

Immediately after connecting the set-top box for digital television, you need to start setting up the equipment. The number of channels directly depends on the type of television broadcasting: terrestrial, cable, satellite. Today, 2 multiplexes are successfully operating. This means that each subscriber will be able to tune in about 20 channels, including regional programs.

There are a huge number of different digital TV providers operating in Russia, which provide the opportunity to configure viewing of additional channels. The size of the monthly subscription fee largely depends on which tariff plan the user chooses.

The process for setting up digital channels on an older TV also varies depending on the type of connection. For example, the Rostelecom company issues a special card to its clients, which is then inserted into the module. This device provides decoding of encoded signals.

To go to setting up channels, take the remote control and press the signal source selection button, mostly it is labeled as “Input”, “AV/TV”, “Source”. A list of sources will appear on the screen, select the one you need.

To start searching for digital channels on old TVs, click on the “Auto Search” button. Wait a couple of minutes until the process of searching for available TV channels is completed. Save the channels. If necessary, you can sort them by changing the location of TV channels.

How to set up a Philips TV with Smart TV

With the advent of more advanced TVs, the channel settings on Philips TVs have changed somewhat. The guide now looks like this:

We head to the main TV menu and go to.
In the following sections we use system recommendations.
Before the search can be started, the system will require you to set the country. You need to choose the one that is presented on the device label on the inside. So, if a device marked PFL is Sweden, since it was manufactured in this country. In other cases, we choose France or Finland.
Go to the category, in the list that opens, set the item.

After these manipulations, the system will require you to set certain parameters. In the section that opens there will be an item called network speed or something similar - opposite it we write the value 6.875.

Then there will be two options for action - full or quick scan. In the first case, scanning may take half an hour, but not only TV channels will be added, but also radio; in the second, everything happens faster.

Quick search

We manually register the frequency fluctuation in the 8 MHz range.
We remove analog broadcasts, if they were already saved previously, and start the search.

Advanced Search

Select in category.
We set the parameter 290.00 MHz.
Click.

If everything was done correctly, scanning will begin and a list of found broadcasts will be displayed on the screen.

How to turn it on without a remote control?

Of course, the easiest way is to use the remote control, press the corresponding button and turn on the AV mode, and then the desired channel. But it often happens that the TV control device is missing or broken. The best thing to do in this case is to go and buy a new remote control. But in life it happens that the remote control is broken, and there is an urgent need to use the AudioVideo mode. There are two ways to turn on the TV if you don't have a remote control:

use the side panel of the TV;
use a smartphone.

The first option is used most often in such situations. Everyone knows that each model has buttons on the back or side panel for control: switching channels, adjusting the sound, activating/deactivating the TV. Usually the buttons are quite small and colored in the color of the body, so they are difficult to notice.

Important! You need to carefully examine the entire TV; there are buttons on every TV model.

There should also be a button to switch between AV and standard modes. They are located differently in different models, so it is better to read the instructions and find information on the location of the switch button. Sometimes you need to use the button control panel to go into the settings and switch modes there. All this information is written in the instructions that come with each TV.

The last method, which involves using a smartphone, is still rarely used. Since the TV must have a control function via an application on the phone. All modern and latest models are equipped with this technology, however, the price for them is appropriate.

Important! You should install an application on your smartphone that will allow you to control the TV.

To switch from standard mode to AV, you should go to the application on your own smartphone. There should be “Settings” or “Mode Switching”. You need to go there and switch the TV to AV operating mode. Do not forget that different manufacturers make such applications differently. Therefore, there will not be detailed instructions for a specific model here.

Possible problems when setting up buttons

There are no big difficulties when controlling the TV using the keys. In addition to being unaccustomed to this option of switching programs, gears and settings. But sometimes the following difficulties occur:

Scroll through settings. Especially when manually searching for channels. It takes a long time to find the right frequency and without a remote control, more time is spent.
The buttons themselves fail. In CRT TVs, the keys become clogged with dust over time and may stop working. This will create great difficulties when tuning and switching channels.
Broadcasting via set-top box. Settings using buttons will not help. The receiver requires a separate remote control.
The child lock feature is enabled. It is installed so that children do not touch the buttons on the TV. And if you don’t turn it off before the remote control fails, you won’t be able to control the equipment with buttons.

What to do if the remote control for the set-top box is broken? Buy a new one. And during the replacement process, you can try switching the signal source to the antenna. And configure at least some channels through the keys on the TV.

Slavic integration

This way you can control any devices, with any phone that can play a sound file. See also this entry if you need ready-made audio signals from any remote control:. This is an application that, using an audio signal, generates the required frequency to send commands to the infrared receiver of the device. Two IR LEDs are used to generate a signal with a frequency of 38 kHz, which the audio output is not capable of. The frequency of one and the second LED is 19 kHz, for a total of 38, which is what is needed. Infrared LEDs can be removed from unnecessary remote controls. The amplification circuit does not pretend to be correct, this circuit is a temporary option for a quick solution - here and now, so that it can be assembled as quickly as possible and have as few connections as possible:

First, it’s useful to set up your Dreambox remote control to work with the TV or receiver remote control, which you can use. However, just kidding, no offense ladies, silicone somehow fits in with you know what.

Control via smartphone

Today, every person has a smartphone in their arsenal. And some even have 2 of them. These devices can become an ideal analogue of a remote control. Modern smartphone firmware already contains a universal remote control program suitable for most TV models. It allows you to turn on the TV, change the channel and change the volume. However, some wide-format multimedia devices still require the installation of a specific application with a wider range of options.

Pairing between your phone and TV requires certain technical specifications of the devices.

A special application must be installed not only on the smartphone, but also on the TV itself.

For Samsung or LG models, in the Play Market you can find several dozen options for unique control panels that correspond to the general class of devices and each individual TV model. For other multimedia devices, you can choose any universal application. The only inconvenience is that the application will have to be installed on the smartphones of all family members.

TV Control Applications

Let's look at the most popular applications that will help you use your smartphone as a remote control.

TV Remote Control

Universal software that allows you to control television equipment using a smartphone. The application does not have a Russian-language version, but the intuitive and simple interface completely compensates for this flaw. Therefore, every user can master the functionality of the main menu.

Set up a wireless Internet connection or synchronize the program and devices via the IrDa interface. Then write down the IP address of the TV, and also select yours from the list of proposed models. The application developers have implemented support for popular models from leading manufacturers: LG, Samsung, Panasonic, Sharp, Akai and many others.

The software has many useful commands for controlling Android TV: power on, numeric keypad, channel switching and sound settings. There are no paid versions of the software with extended functionality, so advertisements will appear periodically.

Easy Universal TV Remote

A program for mobile phones that turns the device into a remote control. This software differs from its analogues only in its interface. Accordingly, the set of commands remains virtually unchanged. Using Easy Universal TV Remote, you can turn on the TV via your phone or change the sound, change the channel, etc.

To get started, just select one of the 3 proposed mobile device connection modes, as well as the TV model. Mostly free programs have one common drawback - there is no option to disable advertising. Accordingly, it is impossible to get rid of annoying banners that overload the smartphone’s processor and interfere with the normal use of the application, as well as to expand the functionality of the software.

Samsung universal remote control

South Korean equipment manufacturer Samsung is perhaps the most famous brand in the world. Of course, the company had no right to leave consumers without a proprietary application that would allow them to use the phone as a remote control.

The program is called Samsung SmartView, and it is presented in the form of a practical and simple utility. The main feature is the function of broadcasting images both from a smartphone to a TV and vice versa. Therefore, you can watch your favorite TV shows even when you are away from your TV device.

If we talk about the advantages, then it is worth highlighting the multifunctionality. The application is designed not only for TVs, but for any equipment from Samsung that is equipped with a built-in IR port.

For users who have several TVs in their home, it is possible to create a special quick access tab for each model. If additional gadgets are connected to the TV device, for example, an audio system or a game console, then using Samsung SmartView you can quickly configure the operation of the equipment within one menu.

Main functionality of the software:

Unique remote control. The user will be able to add his own buttons for various commands, as well as set their shape, color and size. You can also install an icon on each key.
Creating macros. Ability to customize the list of actions in one click. This could be changing channels, changing the volume, or turning on the TV.
Create and save IR codes for various commands.
Scanning models to set up synchronization.
Backup. Absolutely all basic parameters and commands can be transferred to another smartphone without any problems.
Widget for the main menu of an Android smartphone. You can control your TV device without even opening the program.

Onezap Remote

Another very practical, and most importantly inexpensive application for remote control of television equipment. The software database contains over 250 integrated devices: Samsung, Sony, LG, Bose, Pioneer and others.

Users will be able to use a pre-installed menu or create one from scratch. At the same time, they will be able to choose even the color design of the interface, the size and shape of the keys. When a DVD player is connected to the TV, the option appears to create a separate key or set of keys to control several devices.

Ways to turn on and off the TV without a remote control

The simplest task is to ensure the launch. This is done by pressing one button. Setting up will require some effort, so you need to be patient.

Switching channels

It is not difficult. As a rule, after turning on the TV starts working on the same channel on which it was turned off. To switch to another, you need to use Scroll to the desired one.

Unlocking the TV

Some users, in order to prevent unauthorized changes to settings (accidentally, unknowingly, or if there are small children in the house), block control using a password.

You can remove the restriction from the remote control, but it is out of order. There is still a way out.

Reset settings to factory defaults. In this case, all entered passwords will be lost, and Google accounts will not be saved (unless the TV is synchronized with other devices). You will also have to configure your Wi-Fi router again. Different models may reset settings differently. So in most cases you can unlock it without a remote control.

If the instructions are not saved, it is better to download it on the Internet. The most common is the combination of the POWER and “—” keys when the TV is turned off from the network. You need to keep the buttons pressed for 10 to 30 seconds. Then, without releasing them, insert the cord plug into the outlet. Hold the buttons for another 20 seconds, after which a complete reboot will begin. This way you can also unlock the buttons on the TV.

If the TV is locked without user intervention, it will not be possible to unblock it. Such a malfunction can be eliminated by a complete flashing at a service center. During the warranty period, it is better to exchange the model for a working one.

Setting up a TV without a remote control

Of course, it is much easier to do this using a remote control, but it is also quite possible from a manual panel. Let's look at channel settings as an example:

Enable - POWER.
Press the MENU button.
Use the arrows to scroll to the “Channel settings” section.
Click OK.
Select the “Manual setup” menu subsection.
Confirm action - OK.
Select “Auto Configuration”∗ or “Programs”.
OK.
In the “Programs” subsection, assign each channel its own number.
Channel selection - OK.
Adjust to the desired image quality using +/-.
Confirm action.
Exit menu.

∗ If this section is selected, the TV itself will search for channels.

IR remote control for android

Unfortunately, mobile devices equipped with an infrared port are gradually dying out.
For example, the Samsung Galaxy S6 and S6 Edge models still had a built-in IR port, but the subsequent S7 and S7 Edge models no longer had it. This feature is more common in smartphones from Chinese manufacturers. Such phones include Xiaomi Mi5, Huawei P9, Meizu Pro 6, etc. Mobile devices with an infrared port usually have an add-on to the OS or a separate application. However, the functionality of such programs is very limited. Therefore, to control TV via the infrared port, it is recommended to install a third-party TV remote program for Android.

Not all smartphones have an infrared port

How to switch channels on a set-top box without a remote control, control any devices from any phone

See the background here:

-We flash the DVB-T2 set-top box through the console, without soldering the chip

This way you can control any devices, with any phone that can play a sound file.

See also this entry if you need ready-made audio signals from any remote control:

-How to record remote control signals + Recorded sounds from remote controls

If you have a built-in infrared port in your smartphone, then download the irplus - IR-Remote from the link - https://play.google.com/store/apps/details?id=net.binarymode.android.irplus, find it in the application remote control to your device and simply control your device, which does not have a remote control, through this application; if you do not have an infrared port on your smartphone, this application will not work! Use the irplus WAVE and the method below.

An application for Android was found to control the set-top box (you can also NOT control it from a smartphone, read about this at the end of the article) - irplus WAVE

You can download from the GooglePlay website:

https://play.google.com/store/apps/details?id=net.binarymode.android.irpluswave&hl=ru

This is an application that, using an audio signal, generates the required frequency to send commands to the infrared receiver of the device. Simple circuits from the Internet in which IR LEDs are connected towards each other and soldered to a 3.5 mm plug, then inserted into the phone - did not work, because all phones have different voltage output to the 3.5 mm jack - on many phones - such a simple circuit will not work.

Here is this connection that does not work on many phones and smartphones (in the beginning, you can try this simple method by simply connecting the infrared LEDs back to each other):

A temporary solution was found - to amplify the signal using an Operational Amplifier (OP-Amp) - LM324N.

Two IR LEDs are used to generate a signal with a frequency of 38 kHz, which the audio output is not capable of. The frequency of one and the second LED is 19 kHz, for a total of 38 - what is needed. Infrared LEDs can be removed from unnecessary remote controls.

This is an excellent solution - here and now, it can be assembled quickly and has a minimum of wiring; instead of LM324 you can use analogues of this operational amplifier - ULN4336N, GL324, LA6324, IR3702, HA17324, MB3614, NJM2902D, SG324N, TDB0124, UA324, TA75902P, KR1401UD2, KR 435UD2 ( ATTENTION! For other microcircuits, look at their pinout and assemble in accordance with their pinout, since, for some microcircuits, the pins may not correspond to the LM324! For example, the LM324 has “plus” power on pin 4, and “minus” power on leg 11, and the KR1401UD2 microcircuit has “minus” power on leg 4, and “plus” power on leg 11, that is, on the contrary, if you connect the polarity incorrectly, you can damage the microcircuit).

Gain circuit:

R1, R2, R5, R6 - 1 kiloOhm (1,000 Ohm)

R3,R4 - 1 megaohm (1,000,000 ohms)

D1, D2 - Infrared diodes (their glow is visible only on the camera)

BAT1 - Any power source from 3 to 5 volts (batteries connected in series, battery, power supply, etc.)

Audio Left In/GND/Right In - contacts coming from the 3.5 mm plug (from the headphone jack) from the phone - left channel, common, right channel

It is not necessary to take resistors exactly with this rating; some deviation is allowed within reasonable limits, for example, instead of 1,000 Ohms, you can take 800 Ohms, or 1,200 Ohms (1.2 K). Instead of 1 Mega Ohm - 900 Kilo Ohms.

Separate resistors for LEDs are not needed, since the current is limited through the input signal and the microcircuit itself. In addition, some IR LEDs can withstand pulsed current up to 1 Ampere! (they will burn out from a direct current of such strength).

The outputs of the LM324N operational amplifier chip—Output 1 and Output 2—are connected to the positive terminal of the Infrared LEDs.

Please note that IR LEDs may glow continuously (you can see the glow through the camera)

The device is ready, with an optional switch and LED added to indicate that the power is on. You can use a CR2032 battery as a power source - it has just the required minimum number of volts.

This solution can only operate in close proximity to the device, almost right next to each other (also, a command to the device can only work after many attempts). In extreme, urgent, emergency cases and when the remote control is needed only once - a very good solution, for lack of a more accessible and worthy alternative.

Some phones may not see such a device, in order for the phone to understand that a “headset” is connected to it, it is necessary to use some kind of resistor, for example 100 Ohm - 1 Kilo Ohm - to close the Ground (GND) and the right channel, closing the left one may not work. To prevent the headset from stopping To “see” the phone, you don’t need to remove this resistor. You can also just solder this resistor right away to avoid unnecessary movements.

After completing the circuit, just connect the 3.5mm jack plug to the phone connector and launch irplus WAVE.

In the menu - “Add” we look for your device - DVB set-top box, DVD, TV, Satellite receiver or other device you need, if there is no such device in the list - we try all the remote controls of the same type of device as yours, in a row, until one of they won't work.

We added, in the tabs of the added devices, select the required one and click on the buttons - if everything is done correctly and the remote control is selected correctly, everything should work (the LEDs should pulsate when the buttons are pressed - send pulses at a frequency of 38 kHz).

How to do without the application?

It is enough to record the sound into a WAV file that the phone emits when you press a button, which can then be played back on any phone with an amplification device connected (Scheme).

This can be done via an aux cable,

Having recorded sound through the line input, you can also use a microphone or a TSOP IR receiver to record signals directly from the existing remote control - there are a lot of ways, one of them should definitely suit you.

More information about recording via line-in and other methods - How to record remote control signals + Recorded sounds from remote controls (maybe some of the recorded sounds are suitable for your device)

After recording the signals, it is enough to simply play the sound file corresponding to the command on any phone and the device will respond to the command.

The solution was cumbersome, inconvenient, the range was insignificant, and the IR LEDs were always on, which would have a bad effect on the power supplies, so it was decided to make and write a mini-remote control on ATTiny13:

-Universal IR Remote

We use button control

If you remember the first Horizon TVs, they had a large button panel on the front. All the buttons were of impressive size and had additional prompts, so there were no problems with controlling the old devices.

Domestic devices have been replaced by foreign-made models, where all the signatures are in a foreign language. Moreover, the buttons became smaller and smaller. In modern models, there is only a screen in front, so many people believe that the remote control is the only tool for communicating with the TV. In fact, all TVs come with a manual control panel. However, you need to look for it on the back or side wall. It can be so compact that you can simply not notice it.

If you stand facing the display, then on a Toshiba or Philips TV you need to look for the panel on the left, and Panasonic, Bravia on the right. For Samsung and LG, control keys are installed on the back wall. The location may vary, depending on the specific model. We study the instruction manual.

Funai tv-2000a mk8 enable av without remote control. Turning on Av without a remote control - 2018-12-02

Funai tv-2000a mk8 turn on av without remote control Rating: 6.7/10 1878 reviews

There is no remote control and there never will be. After a quick check, it turned out to be a faulty horizontal transistor. Problem: the raster is narrowed horizontally. After the defect appears, when turned on again, start pulses appear for a split second. Does not turn on from standby mode.

Without a capacitor - horizontal shift. During the defect, the power supply to the control processor was +5.8 V instead of +5 V. Workaround: C652 should be replaced with 1 uF x 250 v. . You can turn it on from the TV panel with 3.

Power supply for the Funai video duo 1. I think no one does this in real life and would risk trusting the lives of their loved ones with advice from the Internet. All supply voltages are normal. After disconnecting from the network and completely extinguishing the LED turns on again, but soon turns off again. If you have a TV with teletext, then consider yourself lucky. The problem is with the power supply.

Crack in the plastic roller on the drive motor shaft. Compare with the malfunction in secret 312. Search for the remote control using Funai equipment. The client saw this defect when I showed it to him. Carry out initialization according to the service instructions.

But you can’t watch the third one - even if the image quality is good, there is no frame synchronization. The image periodically disappears, the screen is dark, there is no volume control. Malfunctions are possible during operation - 1. The reason turned out to be loss of capacity C344 1000x25V. We check the voltage stabilization by the absence of changes in the raster when changing the scene. In my case, one of the resistors was broken, and one increased its resistance to 120k. There are four F's in the corners.

Similar malfunctions often arise when assembling televisions, when radiators are installed on the board. In my case, one of the resistors was broken, and one increased its resistance to 120k. . Setting up the 6.5 MHz circuit, replacing the 6.5 MHz quartz, and the video processor did not give anything. If R2M is not broken and the power module does not start, then use a C-meter to measure the required electrolyte 220uF-6.3V. Q652, in the optocoupler circuit, also turned out to be faulty, causing the power supply to go haywire.

But you can only watch them when there is a setting bar on the screen. In manual mode, you can configure channels, after configuration it can work decently for several days. Normal resistance is 0.7 Ohm. After this modification, the TV works satisfactorily. According to my data, the internal capacitor has a rating in the range of 3-9 pF. The cause of all troubles is the ring.

If the frame microcircuit fails, be sure to check all electrolytic capacitors in its wiring. Replace burnt resistors in the stabilizer. There is no supply voltage + 5 V. All fuses are intact 3 pcs. . After checking the voltages controlled by the processor, I discovered that the voltage is increased by 5 volts to power the teletext unit.

Standard manual control

To understand how to set up a TV without a remote control, you need to understand the standard values and keys. They are available in all types of TVs. And these include:

Turn on or POWER. It is located separately and is usually larger in size than other keys.
Go to the menu section - . There are TV models where the same key is used to turn it on, only in this case it must be held for 10-15 seconds.
The confirmation key for the selected actions is OK. There are options where you need to double-click on it to go to the menu.
Switching channels - < and > signs. Located next to each other. They are also used for menu navigation.

The proposed satellite TV set is ordered from us by residents of the city of Kyiv and the region who want to watch an increased number of television channels on their televisions.

Identification of the main buttons on the TV panel

All household appliances controlled by remote control are equipped with a panel with buttons for control and configuration. At first it was considered the main one, and the remote control was considered a convenient application. But gradually the size of the panel decreased and the number of buttons was reduced. They began to be made smaller and hidden on the sides of the body or in the foreground. The leading role in controlling the TV has passed to the remote control.

Due to various circumstances, the remote control may not be at hand (it got lost, broke), so it is important to familiarize yourself with the buttons that are built into the TV body and understand what each of them means

Key and its designation	Functions it performs
POWER	The main button for turning on the TV. Can be located either on the control panel or separately
MENU	Clicking on this button opens a window for controlling all functions of the TV device
OK or INPUT	It confirms that the selected action has been completed.
CH+ and CH-	These buttons are designed to switch broadcast channels, as well as select a specific function in the settings menu

Different manufacturers try not to change the design of TVs and maintain the location of the built-in control panel. For example, in Samsung models it is located on the front surface of the case, and in Philips it is on the sides or back.

Main Features of AV

AV is a special connector located in most cases on the back of the TV. A cable with the appropriate input connector configuration is connected to it. An external device is connected to the other end of the cable, which is responsible for transmitting the signal to the TV.

After connecting the cable and turning on the mode, the TV will receive a signal from the external device. At the moment, this is one of the simplest and most effective ways to receive an external signal from any device. The latter include cameras, video cameras, various players (DVD and the like), mobile phones and other devices.

To correctly connect an external signal transmitter and activate the mode, you must perform the following steps:

Make sure your TV supports AV playback function. The corresponding information is present in the technical data sheet for the device. If your TV has an AV connector, it supports this function.
Purchase an AV cable if it is not included with your TV or connected device. There are different types of such cables. The most common ones include the so-called “tulips” and scart.
Connect an external signal transmission device to the TV using an AV cable.
Activate the AV operating mode in the TV menu. This is usually how it is designated.
Make additional settings if necessary.

Thanks to this, you can quickly connect any AV device to your TV and set up the transfer of multimedia content. The mode is already outdated, but provides high quality video and audio signals even by modern standards.

Turning on from another remote control

When there are several TV devices in the house, it will not be possible to turn on the TV using the remote control from another receiver.

, unless these are two samples from the same manufacturer. This is explained simply - each pair of devices is tuned to a specific signal frequency. Therefore, the Philips remote control will not work with the Sony Bravia.

HUAYU has developed a universal remote control

, with which you can control not only most television devices, but also digital set-top boxes, audio systems and other devices that are predisposed to remote control. This remote control is programmed with control codes for literally all leading TV brands. In case of loss or irreparable damage to your original remote control, it is best to purchase a similar device.

However, to use such devices, they require preliminary configuration. Here is an example of how to properly configure the HUAYU remote control.

You must press the “SET” and “POWER” buttons simultaneously. The successful activation of programming will be indicated by a constant light on the indicator.
Then, by methodically pressing the “VOL” button, you need to find the desired command. As soon as the volume scale appears on the TV screen, you should stop pressing.
Exit from the setup mode is done using the “SET” button. The indicator should go out.

It is not difficult to find a way out of a situation when the remote control is broken. There are several ways to solve the problem and you just need to choose the one that will be more convenient.
