Step-by-step setup and connection of the DEXP digital set-top box
Statistics show that in our country the most popular models of digital set-top boxes are devices from DEXP. They are very reliable in operation, quite easy to set up, and most importantly, they cost around 1,200 rubles. The biggest questions arise when connecting the device to the TV. There are several options on the console, and few people know which one to choose. Therefore, today we will consider all the questions regarding these consoles. We will try to provide instructions that will fit the most popular models: hd 2991p, 2551p, 1812p, 1813p, 2771p, etc.
Keyboard
The input device consists of groups of conductive tracks; when you press a button, they close, which is processed by a multicontroller located on the motherboard.
Keyboard failure usually occurs after it is flooded with liquid - in this case, the buttons usually fail 5-6 at a time. In this case, you need to replace the laptop keyboard with a new one. In rarer cases, the keyboard mechanism breaks down or gets clogged (the buttons are harder to press), in which case the keyboard can be repaired.
Comparison of DEXP set-top box models
The only distinguishing features of the various models of DEXP set-top boxes are the presence/absence of a display on the body, as well as unimportant dimensions. In general, all devices are similar in parameters. The most popular console models on our market are presented in the table.

Options for connecting to a TV using the example of DEXP HD 2991P
In order to clearly demonstrate to you the procedure for connecting DEXP set-top boxes, we will take one of the popular models - HD 2991P. According to reviews, this console is one of the most reliable. According to the characteristics, it has the following parameters:
- Plastic case.
- Work with modern file formats.
- 2 USB ports.
- Possibility of connecting to a TV via HDMI and RSA cable.
- EPG mode - built-in program guide.
- PVR mode - recording TV programs using a timer to a USB drive.
- Delayed viewing.
- Possibility of blocking some channels to protect against children.
To connect to a TV, we need to navigate depending on what connectors it has:
- If there is HDMI, then preference should be given to it. The same thing should be done if you want to connect the set-top box to a computer monitor.
- If you have an RSA input or SCART, you will need to choose regular tulips.
HDMI connection
The set-top box usually comes with an RSA cable. Therefore, you will have to purchase HDMI yourself. It costs around 500 rubles.
However, if available, it will allow you to connect even to ordinary computer monitors. To connect, just connect the TV directly and then insert the antenna input into the set-top box. After that, switch to Audio-Video (AV) mode. If connected correctly, the device menu should open.
SCART and RSA connection options
In practice, older TV models usually do not have HDMI connectors. Some models only have SCART. In the first case, it will be enough to use only “tulips” when connecting. They are connected directly by color. 2 connectors usually go to Audio inputs (R and L), the remaining one remains for Video.
If the TV only has SCART, you should purchase an additional SCART-RSA adapter. It's not difficult to find. It looks like this:
HDD
The hard drive or SSD drive contains the main system files, programs and your personal data. Damage to the hard drive occurs as a result of shocks or shaking while the laptop is running, while ssds, on the other hand, are not afraid of shaking, but they fail as a result of liquid ingress or a short circuit in the laptop's power circuit.
If the hard drive is damaged, the laptop may stop booting or a blue screen may appear while the system is running. Our specialists will check your hard drive for bad sectors and, if any, will replace the hard drive and install the system. Data located on a damaged disk can be retrieved for a fee.
Setting up 20 channels on a DEXP digital set-top box
After the device is connected, you need to perform an initial search for channels. With proper configuration and antenna selection, the device should find up to 20 free digital broadcast channels. The sequence of actions to enable and search is as follows:
- We turn on the TV and set-top box to the network.
- Select the display mode in the TV menu. It is selected depending on how the device was connected. If it is HDMI, then select the mode corresponding to it; in the case of tulips, you need to set it to AV.
Manual search
In most cases, the manual search mode copes with its task and, with the correct choice of antenna, finds the entire available list of TV channels. However, in practice, there may be times when it will be necessary to reconfigure everything manually. To do this you should:
- Find out the digital signal reception frequency for your broadcasting region. To do this, you need to go to the interactive CETV map and select the TV tower closest to your home.
- After this, in the device menu you should select the “Search for channels” section and go to manual search.
- In the window that opens, you should set the channel number and make sure that the signal strength has appeared.
- This should be done for both multiplexes.
You can change the list of found channels, set their order, etc., through the program editing section. When you log in, you will be prompted to enter a password. If you have not done this before, it will be: “000000”.
How to setup?
Installing and setting up YouTube on a DEXP TV is a simple and straightforward task. All you need is your TV and an Internet connection. If you bought a completely new TV with a pre-installed program or want to set it up on your old Smart TV, the algorithm is approximately the same.
First you need to remove the old version of the program. You can do this by going to the main menu of the Play Market, and from there to the “My Applications” section. A complete list of applications that you have ever installed on your devices will appear on the screen. Find the YouTube icon among them and click on it. The application page will open. Click on the “Delete” button and confirm deleting the application.
Now you can download the latest version. A green “Download” button will appear in place of the delete button.
Once you click on it, the installation of the application will begin. After its completion, the button name will change to “Open”. You can launch the application. Usually the steps described above are enough to get things working again. The program will make more precise settings automatically after launching the application. If not, and you still cannot access your hosting, it’s worth looking into a deeper solution to the problem.
If Dexp doesn't find channels
During operation, various difficulties may also arise, due to which the set-top box may not find channels or not see the TV. In this case, there are several obvious solutions.
Can't find channels / Searches less than 20
- Check again that the device is connected correctly. Some adapter or cable may fail.
- Make sure to select the correct antenna. The greater the distance from the TV tower, the stronger it should be.
- Try retuning channels manually, making sure that the signal strength is available.
The set-top box does not see the TV
- Check your connection method again. Check to see if you have selected the display mode correctly. If the set-top box is connected via an HDMI cable, then you should select this mode on the TV. For RSA, you need to go to AV.
- The image plug may fail. This often happens on tulips. The third wire, responsible for Video, fails and as a result the picture is not displayed.
The console constantly reboots and turns off
The reason for this problem is software errors. It should be updated and the device should be flashed. This can be done via USB. To do this you need:
- Write the firmware file to a flash drive with a capacity of up to 4GB. You can download it on the official Dexp website.
- Insert it into the device and go to the “System” section.
- Click on software update and then select the previously recorded file.
- Once the installation is complete, the set-top box will reboot on its own.
If the remote control does not work
If there is no signal at all, you should replace the batteries with new ones. If the problem does not go away, then most likely the remote control is faulty and should be replaced. On some TVs, there may be a problem in which some remote control buttons will not work. For example the volume button. In this case, you can try to flash the console.
Troubleshooting
This problem began to appear in 2021, after a change in the video hosting policy, on devices from different manufacturers.
Attention: the method is suitable if the device parameters have the “APIkey import” function (press the gear-shaped button on the remote control, “settings”, etc.) For example, if you are looking for why YouTube does not work on the Selenga T42D smart TV set-top box, T81D, HD950D, T20DI (on which you can import keys from an external drive), this method should work. .
We warn you - setting up is not that easy!
- Follow this link .
- If you don't have a Google account, you need to create one.
- You must enter the YouTube Data API v3 section.
- Click on the blue “Enable” button.
- If you see a message that you do not have enough rights: Click "Select a project" at the top. If there is an option in the window that appears (for example, a YouTube channel), you need to choose it. Or click "Create Project". Wait for notification of successful creation.
- Now the “Enable” button will become active. After clicking, on the next page you must click “Create credentials”.
- Fill in all the fields: data type (YouTube Data API v3), where you will call from (web server), what data you will access (public). Click "Fill".
- The API key field will be filled in. Click “copy”.
- You need to create an XML file. You can take the template here, then open it with notepad and paste the copied key instead of the many question marks.
- Copy the file to a USB flash drive, then connect it to the set-top box.
- Start importing apike from USB on the set-top box, restart the application, after which everything will start working.
And here it is - Take it easy ↓
Lumax
Devices from this manufacturer have become very popular due to their low price. If YouTube does not work on the Lumax console, first of all you need to check the software version. You can update both over the network and via USB.
1. Network update.
- The Lumax set-top box in the internal menu has the following sequence of functions: “System” - “Software update” - “Update via network” - OK.
- Wait until the download completes, then reboot your device.
2. Update via USB.
- On your computer, download the installation file from the manufacturer’s website https://lumax.ru/support/ (pay attention to the compliance with your model).
- Unpack the zip folder, the file must have a .bin extension.

Another popular type of gadget. But after the latest YouTube updates, it does not work on the dune tv set-top box model HD TV 101. For a long time, the problem seemed insoluble; many users even advised getting rid of dune and purchasing a new console.
- Download the special plugin here.
- Log in to YouTube from your computer into your account.
- We press the blue button on the remote control of the set-top box and enter the address from the TV screen on the computer in the address bar of the browser.
- A window will appear on the PC for entering a special code - you must enter the code from the set-top box into it.
- You can start watching on TV. ????
Smart TV
It’s worth talking about smart TVs separately. As a rule, after updating the system, the YouTube application itself may disappear, or the videos may stop loading. All problems can be divided into the following groups:
- Older TVs (pre-2012) simply don't support HTML5. For such models it is recommended to use smart set-top boxes. Sometimes videos continue to be produced through the TV's main browser.
- If your TV supports this function, you can try launching YouTube from your smartphone by connecting the broadcast to the big screen.
- For older models, installing ForkPlayer may be effective. The software developer has instructions and tips for all models.
- Make sure that the problem is definitely in the application and not in the Internet connection (launch your browser and check if it works).
- In new models, first of all, you need to restart the TV by disconnecting from the network for a few minutes. Then update the software over the network using the standard function in the menu.
- On LG TVs, after updating the firmware, some programs may disappear completely. In this case, install from LGStore again.
- If YouTube freezes, try uninstalling the program and installing it again.
- If none of the methods help, perform a general reset to factory settings.
If you have another problem, please let us know.

Reviews on the DEXP set-top box
Dexp consoles were among the first to appear on our market. With the advent of the first multiplex, their cost was slightly above 1000 rubles and for most models remains the same.
On the Internet you can find many reviews of these consoles. When choosing, we advise you to focus primarily on newer models, for example 2991 and similar ones. The fact is that not everyone can update consoles. As a result, there may be problems with the software when connecting to the TV. It will simply refuse to work with this console or will do it incorrectly.
Another advantage of the new models is more stable elements. According to reviews, some models begin to make noise or burn out after 1-2 years of operation. This is primarily due to the use of cheap components. On the same 2551p this problem has already been fixed.
Thus, in general, users are satisfied with this set-top box. If the antenna is configured correctly, it is capable of picking up all digital channels available in broadcasting.

Features of DEXP TV tuners
When choosing a tuner to switch to digital TV, users focus more on price and functionality. The DEXP digital TV set-top box is always an inexpensive device with the necessary minimum capabilities. All models are quite compact and have the necessary cables for connection included.

Popular models of DEXP set-top boxes
The most popular tuners according to user reviews are the following models.
- DEXPHD1812p - plastic case with display. Maximum resolution - FHD, tuners - DVB/DVB-T2, recording and reading of USB media. Functions - Shift, TV guide, teletex. Connectors - USB, HDMI, RCA, antenna input and output. There are buttons on the body for control. External power supply.
- DEXPHD1813p - similar to the previous model, the difference is the absence of a display and control buttons, the power supply is inside the case.
- DEXPHD2551p - functionality is similar to previous devices. The main difference is a minimalist body without a display or buttons, and there is no antenna output. Connection to TV - HDMI.
- DEXPHD2771p is an analogue of HD 1812p in a metal version.
- DEXPHD2991p - analogue of HD 1812p without antenna output.
Advice! When choosing, you should focus on models with a display and controls on the body. It is also recommended to choose set-top boxes with an external power supply, as they heat up less, and the unit can be replaced in case of breakdown.
Checking DVB-T2 on the device
Before purchasing a receiver, it is important to make sure that your TV supports DVB-T2. For this:
- Read the instructions included in the kit. All the characteristics of the TV are indicated there.
- Use the Internet by going to the manufacturer’s official website. Find your device model and view the settings.
- Via Yandex.Market. Enter the model name in the search bar, go to the page with your TV and in the parameters tab, find the “DVB-T2” item.
Connecting a tuner
Installing a digital television set-top box from DEXP is quite easy.
- The antenna cable is inserted into the ANT IN connector.
- Connecting to a TV can be done in different ways. If the DEXP digital television set-top box will also be used to watch video from a flash drive in high quality, then it is best to use HDMI. If the TV does not have such a connector, then you should use RCA tulips (connected according to the color scheme). If the set-top box will perform the basic task of broadcasting channels, then you can use an antenna cable - it is inserted into the ANT OUT connector and the corresponding input on the TV.
- The device is connected to the electrical network.
Receiver setup
The last stage of connection is setting up the DEXP digital television set-top box. It can be performed automatically or manually.
For automatic search, proceed as follows.
- The TV is turned on for display through the connector used for connection (HDMI, RCA or DTV).
- The receiver menu will open, in which you must specify the country of location and interface language.
- The OK button on the remote control starts an automatic search. It should indicate the DVB-T broadcast format. After completing the procedure, you must save the result.
If the automatic search does not produce results, or the sequence of channels does not suit the user, then you will have to configure the device manually. The digital set-top box for the DEXP TV is not much different from other manufacturers, so to search you will need to find out the broadcast frequency in the region where you are located (can be found on the interactive map of digital broadcasting by the name of the locality). After this, a manual search is started, the frequency is entered, and each channel, once found, is saved individually.

Motherboard
Carries out the main work of the laptop; it contains the processor, RAM, video card, other chips and connectors.
Breakdowns occur when the motherboard overheats, when liquid gets in, after a shock or fall, during power surges, over time (after 5-7 years).
Symptoms of a board failure:
- The laptop does not turn on and does not respond to the power button;
- no image appears when turning on the laptop;
- constantly reboots;
- the system does not boot;
- an error appears when initializing drivers;
Connecting and setting up the Dexp digital set-top box
You can watch digital TV either directly from the TV (if it has a built-in DVB-T2 receiver) or using a digital set-top box. The most affordable models currently available are from Dexp. These set-top boxes can be purchased from 600 rubles per device. But I note that such cheap models have a high return rate, that is, there are a lot of defective products.
The entire process of setting up digital television can be divided into two stages:
- Connecting to a TV
- Technical setup of the Dexp digital set-top box
Standard equipment
Hinges or hinges
Using hinges, the upper part of the case is attached to the bottom, as well as opening and closing the laptop. Over time, the factory lubricant in the hinges dries out and opening the laptop becomes more difficult; the bushings, unable to withstand the load, are torn out, which leads to damage to the case . Service center specialists will carry out preventive maintenance and, if necessary, replace faulty hinges.
Digital set-top box Dexp: how to connect it to a TV
The connection can be made by following simple instructions, let's get started:
- To begin with, take the receiver out of the box, get rid of the protective films and unnecessary elements. Check the package to see if all plugs, plugs and connectors are in place.
- Next, we select the tuner connection option: To connect the set-top box to an old TV without an HDMI connector, you can use tulip-type connectors. To do this, use a color scheme and connect the plugs to the desired colors.
Connecting with an HDMI cable Connecting with tulips
- If there is a more modern way to output images, then we use HDMI. This move will make the connection task easier, and the output quality will be much higher. To do this, simply connect one input of the set-top box to the socket of the same name on the TV body.
Connection diagram for tulip plugs and HDMI cable
- Now connect the antenna. In the diagram you can also find a socket for it, which should be on the back side. After this, the antenna must be installed in a suitable place where the signal will be received more reliably. If you have an outdoor antenna, you may have to point it towards the repeater. You can find the location of the tower on the digital broadcast coverage map. Read about where to point the antenna here.
- Insert batteries into the remote control and turn on the TV. At this point, the connection steps are completed, but the work is not yet completed.
For full use, you need to configure digital television.

Technical setup of equipment
The technology for setting up digital TV is not the most complicated; if all conditions are met, you will definitely be able to achieve the result:
- Take the remote control and find the “Menu” button, move on.
- In the window that opens, find the “Settings” section and select it.
- Check the set region, the default is usually Russia. Otherwise, change the region to your own.
- Select the signal standard. It happens that there is an analog signal DTV-T, it is better to change it to digital DVT-T2. If necessary, you can select both options, after which the search for new channels will begin.
- After these steps, you will be asked to choose between automatic and manual channel selection. If you can enter the search parameters yourself, then choose manual, but the easiest way is to use auto-search for channels - the set-top box will do it itself. If you choose the first option, select “auto search”. You just have to wait a little until all the channels are detected, the process may take a while. The main thing is to click the “save” button when the search is complete. There should be 20 broadcast channels.
- When performing a manual search, it is necessary to find out the frequency of each TV channel on which it is broadcast. If such information is available, then enter the modulation parameters, frequency and transmission speed.
It is important to know that with an automatic search, fewer items may be found, or even none at all. In this case, try performing the operation manually, knowingly removing all access to the content. Also, a manual search will help to return a previously deleted channel.
And one more thing - pay attention to the signal level, it is desirable that its quality is at least 30%. If it is less, then most likely few or no channels will be found.

Frame
The laptop case consists of four main parts: the top cover (laptop screen cover) - the screen is located in it, the screen frame - snaps onto the laptop screen cover, the topcase - the part where the keyboard and touchpad are located, tray - the part on which the laptop stands, most often The board is installed into this part and the hinges are screwed in.
Breakage of the laptop case occurs mainly due to improper use or over time the plastic dries out and the bushings to which the hinges are attached break out, breaking the case. If you contact the service center in the first stages of a breakdown, when clicks appear when opening or closing the laptop, you can make repairs in fairly small amounts, but if the plastic has already broken completely (a part has fallen off the laptop), then in this case you will only need to replace the case on new.
