Instructions and manual for Polar 55LTV6003 in Russian

If you purchased a new TV, changed your cable operator or broadcast type, then the first procedure you will encounter is setting up TV channels on your TV.

Depending on the method of signal reception, there are three main types of broadcasting:

• terrestrial - broadcast from a TV tower is transmitted to a regular antenna;
• cable - channel packages from the operator's distribution center are transmitted to subscribers' apartments by wire;
• satellite - the signal from the satellite is transmitted to a parabolic antenna (dish) and converted by the receiver.

In turn, terrestrial and cable television can be analogue and digital. The second has higher image and sound quality, but viewing it may require additional equipment in the form of a digital set-top box (tuner), especially if we are talking about an older TV model.

This article discusses automatic and manual tuning of analog channels on a TV (for cable channels everything will be identical).

Preparing the TV

Before you start directly setting up channels, you should connect the TV to the broadcast source. With an analog signal, the cable from the antenna or cable television operator is connected directly to the antenna input of the TV (marked in the photo):

At the same time, it is worth separately considering the situation in which more than one TV is used in the apartment. In this case, a special antenna splitter is used for connection, which in most cases has two or three outputs:

How to tune channels from a regular antenna to several TVs?

People often complain that the channels on their TV in one room are worse than in another. Some of them are missing, and the rest have interference. This is due to an incorrect connection. It is important that both TVs are equidistant from the main cable. Otherwise, the one that is located closer will take over most of the signal. Also, to connect two or more TVs, you should use a high-quality cable that is better protected from interference. Therefore, a standard cheap cable, which is usually offered by many cable television operators, will not work here.

What is the difference between digital television and analogue?

Almost the entire world already uses digital broadcasting (DV). Unfortunately, our country is still an outsider and the gradual transition from analogue to digital television began quite recently.

These two broadcast standards are fundamentally different from each other. A digital signal is a set of digital codes.

Thanks to this, the data reaches the user equipment without distortion, while the analog signal is subject to interference and is affected by the distance of stations. As a result, it can be stated that digital data transmission is ideal.

The set of codes is received by a special receiver, which decrypts them and broadcasts them to the TV. Such a unit is already built into modern TVs by the manufacturer, but in the case of outdated television receivers, it is necessary to connect additional equipment - a “receiver” or, as it is popularly called, a “set-top box”.

There is a large selection of devices on the market today, but the essence of the process of connecting them is the same for all models.

After connecting the set-top box, even to an outdated TV, the user will be able to enjoy the quality of digital television and watch their favorite shows and movies in high definition.

How to automatically tune channels on your TV

This is the easiest way to set up and requires a minimum of effort and knowledge. The TV itself finds all available channels and remembers them.

To switch to automatic tuning mode, enter the TV menu by pressing the button on the remote control. Depending on the model of your TV, this button may also be indicated by the words HOME, INPUT, OPTION, SETTINGS or special symbols in the form of three longitudinal stripes, a house, an arrow in a square, and others. More detailed information on this matter is contained in the instructions for operating and setting up TV channels. Some options for designating the menu button are shown in the photo:

After entering the menu, use the navigation buttons to select “Channel setup” - “Automatic setup”. After this, indicate what type of television you are going to tune in (terrestrial or cable) and start the search process by pressing the ENTER/OK button. In different TV models, the names of the described menu items may differ slightly, so if you have any difficulties, check the instructions. An approximate menu screen might look like this:

In some cases, before tuning channels on a regular antenna, you should additionally select the region of your location. To do this, in the settings menu, find the COUNTRY or REGION item and select the corresponding entry in the list.

After auto-tuning of channels is completed, a sorting menu may appear on the TV, with which you can arrange the found channels in an order convenient for viewing.

It is worth noting that when changing or adding transmitted channels on the part of the cable television operator, the setup must be done again.

Types of connections

Depending on what connectors the TV and set-top box are equipped with, the connection methods also differ.

The receiver can be connected to the TV via:

1. “Tulip” - RCA wires;
2. "HDMI";
3. Coaxial cord (antenna).

RCA cable

This is the most common and widely used method of connecting a set-top box to a TV.

Although the video broadcast resolution is not as high as with the “HDMI” option, the difference is practically not noticeable to the naked human eye on a TV with small screens.

Due to the fact that each connector and plug of the Tulip connection is painted in a bright individual color, it is very difficult to make a mistake during the connection procedure.

The meanings of the color designations are as follows:

1. Yellow for video signal;
2. Red for audio output;
3. White for audio input.

The user is only required to insert a plug of a certain color into a connector of exactly the same color. Then install the cable coming from the antenna into the “RF IN” connector.

If the TV does not have color “RCA” connectors, then the use of “Combs” is allowed.

It is labeled “SCART” on the back of the TV. You will need to use a cable with the appropriate plugs, as shown in the figure below.

HDMI connector

If the equipment has this type of connectors, then the quality of the image and sound will be significantly higher. In this case, you will need to make a connection via an HDMI cable.

It allows you to provide video resolutions reaching 1080p, and audio quality – 192 kHz.

Antenna cable

When the TV does not have more modern interfaces other than the antenna input, the set-top box can be connected to the TV via the “RF-OUT” connector.

For this purpose, it is necessary to use a special cord, as shown in the photo below.

Unfortunately, this connection method will lag far behind in broadcast quality, but consumer requirements for an outdated or old TV are initially low.

How to manually tune channels on your TV

For all its apparent simplicity of automatic configuration, it has several significant drawbacks. Some channels may repeat or have distorted picture or sound. In this case, you should correct the situation manually. Here are step-by-step instructions for manually setting up TV channels:

• In the “Channel Tuning” menu, use the navigation buttons to select “Manual Tuning” and press ENTER/OK.
• Select the “Program” item and assign a serial number to the channel by pressing the number buttons on the remote control.
• Select the color system used in your region: PAL, SECAM, NTSC or AUTO.
• Select the sound system: 2.0 (stereo), 5.1, etc.
• Perform a “Search” for the channel and, if successful, add it to the TV’s memory by pressing the “Save” button.
• Repeat the same procedure for all required channels.

The manual channel tuning menu may look like this:

It should be remembered that all actions in the proposed instructions are confirmed by pressing the ENTER/OK button.

Frequently asked questions about setting up analog channels

Sometimes during the process of setting up channels certain questions may arise, some of which are discussed below.

How to tune channels on a TV without a remote control?

The process of automatic and manual setup in this case occurs in a similar way, but to access the TV menu, buttons located directly on its body are used:

If there are no such buttons, you will need to purchase a remote control.

How to tune channels on an old TV?

In the absence of a menu, channel tuning is carried out using special controls, which can be located under the switch buttons or on the back side near the antenna connector. In addition, on old domestic TVs such as “Electron” or “Rubin” and portable car TV receivers, bands can be switched using jumpers, sliders or buttons. Setting up television channels for such devices is done only by hand.

What to do if the channel settings are lost?

If you tuned channels automatically, try running a manual search. If the channels fail again, the cause should be sought in a poor broadcast signal, a faulty cable or a broken TV. Read more:

Settings

TVs from Polar do not cause any particular problems. You can configure channels like this.

1. Using the remote control, you need to enter the “Menu” by pressing the corresponding button.
2. Select “Channels”.
3. In the “Broadcasting country” column, many experts recommend indicating Germany.
4. In the “Broadcast mode” item you need to select the appropriate format.
5. Click “Autosearch” and select the “ALL” category. If you need to connect only digital channels, then you should click on “DTV”.

When setting up cable television, you must enter network parameters. After you finish searching for channels, you can separately set up your favorites for quick access. Additionally, in the settings you can select parameters for colors on the screen and sound. You can also set the time, which will subsequently be displayed.

AV/TV mode

To set up in this mode, you need to enter “AV/TV” using the TV remote control.

After this, the settings will be displayed on the screen, where the following columns are present:

You need to specify the column corresponding to the physical connection of the devices, for example, if the set-top box is connected to the TV via a tulip, then click “AV”.

Specify “HDMI when connecting with an HDMI cable.” When using a “comb” - SCARD.

Some TVs, after entering the “AV” menu, automatically switch to “AV1”, ..., “AV5”, etc.

In this case, you need to experimentally find the menu by simply searching through them and make the settings.

Operation and repair

The instructions for the TV fully describe all the actions that can and cannot be performed with this equipment. There is a diagram of how to use all additional connectors. It is possible to connect a phone, video camera, computer, soundbar and much more. It happens that the device begins to behave atypically. Here are common problems with Polar TVs and their causes.

1. Channels do not change, the remote control is broken. In this case, you can try to send it in for repairs. If it cannot be repaired, then a universal remote control will do. Some models have buttons on the body. Then you can turn on any channel without the remote control. Otherwise, you will have to not use the equipment at all during repairs.
2. The TV does not respond to commands from the remote control or control buttons. There may be several reasons. The most common ones are that the remote control or buttons were damaged as a result of mechanical damage. If this option is excluded, then the problem is that the software is not working properly. In this case, you will have to update the firmware.
3. The equipment does not respond to external devices. We are talking about an antenna for analogue, digital television or a TV set-top box. It happens that the TV simply does not output a signal through a particular port. First you need to try setting up channels manually. If this does not solve the problem, then you will have to contact a specialist. The equipment behaves in a similar way if the connectors are damaged or the functionality of the motherboard is impaired. In some cases, the failure is systemic - then you need to change the firmware.
4. The TV turns on, but the color reproduction is disrupted. The picture ripples or appears negative. The reason may be mechanical damage to the display or malfunction of its cables. Rarely does the problem lie in the video signal processing board.
5. After turning on there is sound, but no image is displayed. The problem lies in the display backlight lamps. The technician can make a replacement.
6. The TV does not connect to Wi-Fi. It happens that the signal disappears suddenly. You can try restarting the router and TV. If this is your first connection, you should contact your provider. Sometimes router settings prevent connection.
7. The screen narrowed. You can expand the image quite simply. Just go to the “Menu” and select the “Image” item. So you should find “Image size” and set the necessary parameters. You can also perform the default setting.

Required Equipment

To view DV you definitely need a receiver. First, it is recommended to study the instructions for the TV, since many TVs, for example, from and Philips, are already equipped with the necessary equipment.

This is indicated in the user manual and in this case there will be no need to incur additional financial expenses for the purchase of the set-top box.

If the TV is not equipped with such a unit, then based on the user’s personal needs, you need to buy a receiver with a suitable set of functions.

For example, if a TV owner prefers to use flash drives to watch movies recorded on them, then it is better to ensure that the set-top box has a USB connector.

The components included with the device include everything necessary to quickly put it into operation.

Typically this list includes the following:

1. Instructions;
2. “RCA” wire or as people used to call it: “Tulip” or “HDMI” cable;
3. The tuner itself, that is, the set-top box;
4. Cardboard box with a picture of the device and its brief characteristics;
5. DU;
6. Batteries for remote control;
7. Power unit;
8. Warranty documents.

Sometimes the list of components of individual budget models may lack a cable or other important element, without which it becomes impossible to connect the equipment.

In this case, you need to separately purchase the missing components and only then proceed to connect the device to the TV.

Review Reviews

Buyers claim that for such a price Polar TVs are good. The image quality of most models is satisfactory. The pleasant design of the case itself allows you to successfully fit the equipment into any interior. TVs are good for those who need a temporary solution or a simple panel without unnecessary add-ons.

Users note that the price of the entire model range is more than acceptable. For that kind of money, the manufacturer offers good quality. The remote controls are quite high quality. However, replacing the element with a new one is problematic. In the event of a breakdown, you can only use a universal remote control, because it is almost impossible to purchase a branded one.

Many users complain about the sound quality. Volume adjustment on some models is not smooth enough. Too little frequency range. Some buyers claim that additional speakers solve all problems with sound quality.

For a review of the Polar TV, see below.

Almost all cable providers provide digital television services, and many operators have also retained the analogue broadcast format, which means that subscribers do not need to purchase digital set-top boxes.
