I am repairing Tricolor receivers and did not expect that my personal B210 receiver, which I recently received when exchanging “old” equipment for “new” equipment, would break down after just half a year.
The diagnosis is simple: “Does not turn on”, “does not light up red or green”
I am an inquisitive person and therefore did not bother with the guarantee.
When measuring the supply voltage directly on the board, the 12 V voltage drops to 0.5 V. Although the unit separately produced voltage as it should. Testing for a short circuit showed that there is no short circuit at the receiver input. How so?
This means that the voltage sags on the secondary power circuits, after the pulse-width modulators.
That's right, it's all about low-quality parts.
After PWM, I closed the SMD capacitor to 25 µF.
A GS B210 receiver was brought in for repair with a malfunction and does not turn on; upon acceptance, the receiver was checked and indeed, when you turn on the receiver, it only shows the boot screen and then nothing happens. These receivers are known for their typical malfunction, when the nand flash firmware S34ML04G100BHI000 crashes by itself. This flash drive can be flashed with any programmer that supports nand firmware; there is nothing complicated in the firmware technology itself; if anyone who has ever used a programmer will do it without difficulty.
Diagnostics and repair of the GS B210 receiver
Any diagnostics begins with an inspection of the printed circuit board and soldered components; after we are convinced that no mechanical damage is detected, we proceed to measuring the supply voltages; I prepared measurements taken on a working receiver.
Receiver voltage ratings GS B210
- U19 - 5v
- U16 - 1.5v
- U22 - 3.3v
- U20 - 1.1v
- U18 - 1.2v
- U2 - 3.3v
- U21 - 14v
After checking the power supply and making sure that everything is in order, then you need to unsolder nand and flash it, I use a programmer from the ejtag.ru forum, it is easy to use and works with many microcircuits, I also use it for flashing TVs, the only inconvenience is that it requires 2 times to roll the balls onto the microcircuit, but you can buy an adapter socket and screw the socket with zero effort; you can buy it on Ali, or I’ll give you a link at the very end.
There is nothing complicated in soldering the nand microcircuit itself, you need to apply flux around the perimeter of the microcircuit and solder it with a hair dryer, and here for each master individually everything depends on the equipment and soldering habits, for example, I use a cheap soldering station and the temperature on the hair dryer is always at the maximum, but here you need to not overdo it and not overheat the microcircuit.
After soldering, you need to use a braid to collect the remaining solder from the nickels so that the nickels are smooth.
Next you need to roll the balls onto the chip, I use 0.45 balls and a BGA63 stencil from a Chinese set, the links will be at the end.
After the firmware was installed, the receiver started working normally.

Reasons why the Tricolor receiver may not turn on
Failure to turn on the receiving equipment may be due to:
- Supply of food;
- Switching the TV to another connector;
- Technical work at the provider;
- Problems with the antenna;
- Signal conversion in the converter has stopped;
- Damage to the cable or F-connector;
- Software failure;
- Technical malfunctions in the operation of the receiver;
- The remote control does not work.
To detect a problem, the user can carry out simple steps that involve diagnosing the equipment. Moreover, it is possible to evaluate the performance of individual links or the entire signal supply chain from the antenna to the receiver.
Familiarization information before self-diagnosis - special symbols
A Tricolor subscriber, if he has certain knowledge and skills in electrical circuits or power circuits, can diagnose a broken receiver with his own hands. This will avoid long-term restoration of the receiver’s functionality in service centers. Having decided to open the equipment, the user must know the special symbols used on internal elements.
Triangle with an exclamation point inside
The meaning of the designation is safety. If this warning is marked on some parts, handling these parts may damage accessories or the receiver itself.
Triangle with lightning inside
The meaning of the sign is a threat. Lightning indicates danger during opening or situations where elements are being handled. Danger involves harm to health or life.
Circle with English letter i
The designation provides information about problems and malfunctions that may arise during work.
Search for Tricolor TV - list of regions not available
Difficulties associated with inaccessibility of regions can arise for any Tricolor subscriber, regardless of his place of residence, connected services or installed equipment, for example, gs8306. But most of the probable sources of such a malfunction can be easily and quickly eliminated. A short search for a breakdown or insufficiently reliable contact can help restore the broadcast.
And in the most difficult situations, when they cannot cope with problems on their own, users can turn to professionals. They will definitely restore contact with the satellite.
In 2005, the Tricolor TV company began operating. They soon became the first in the field of providing the population with affordable digital television. Tricolor TV improves the quality of broadcasting, expands the list of channels, and increases the range of digital TV packages so that customers receive quality services for their money. Technologies are developing, progress is being made.
In 2014, the company invited customers to switch from old brands of receivers DRE and GS to new ones - B210 and B211. But a problem arose: after replacing many, the message “the list of regions is not available” appeared on the screen. Tricolor TV assures that there is no reason to worry - the problem can be solved. The region list becomes unavailable even without changing the receiver.
Nutrition problems and their solutions
Testing of GS series receivers.
The first priority is always to check the power supply:
- Is the plug plugged into the socket?
- Is the power supply OK?
- Correct connection of the power supply to the network;
- Is the wire disconnected from the console, because sometimes children can accidentally remove it;
- The power switch on the rear panel should be in the On position.
Models of older receivers typically have an external power supply. The power problem may be a malfunction of this element. A Tricolor user can buy a new unit and enjoy watching television.
On new models, the power supply system is located inside the case, which complicates the repair task. Power may not be supplied due to lost capacity or defective areas on the diode bridges. Also, a unit that is used for a long time may fail over time. During repairs, you will need to replace the capacitor, which is swollen. Having disassembled the receiver case, you can immediately distinguish the power supply. By disconnecting it from all the boards, a skilled craftsman will be able to replace the failed elements.
Video: how to replace the power supply on the GS8300 receiver
To simply replace a capacitor you will need:
- Soldering iron;
- Screwdriver;
- Soldering flux;
- New capacitor.
When opening a part, the location of the element must be observed. When soldering a new capacitor, observe all boundaries.
Repairing the power supply will allow the current to flow again. If power is supplied, the indication is activated. Maintaining the “non-switchable” state in the presence of an indication is associated with other breakdowns.

Message No signal on TV
When a message appears, the subscriber first checks the likelihood that it is coming from the receiver and not from the TV. The indicators on the receiver light up, and when you press the buttons, a response occurs. When you call up the Receiver Menu, the device displays the corresponding window. This means that the equipment is correctly connected to the TV, and the error is related to the operation of the receiver.
If the weather is good outside and the provider does not carry out technical work ( information about technical work is presented on the company’s website or displayed in advance on the Info Channel ), then the message may appear due to the following reasons.
Antenna offset
The antenna goes astray under the following conditions:
- Bad weather;
- Poor fixation;
- Long-term operation;
- Fall of a heavy object.
A displacement of 1 cm causes the signal to disappear. The user needs to analyze the rigidity of the fastening. If the fastening is found to be weak, adjustment will allow you to achieve the desired signal range. The signal is monitored on the television display during the period when the “Settings” section is turned on in the receiver Menu.
After the initial adjustment, it is necessary to perform a fine tuning operation so that the corresponding signal parameter scales are filled at the level of 70-80%. The final step involves securing the pole bolts to the antenna.
When a large object falls on the antenna, it leads to changes in geometry, which requires a change of equipment.
Often, changing your position on your own does not bring positive results. A dish installation and setup technician will be able to quickly set up the signal. The cost of services depends on the region and location of equipment installation.
Correct time setting
The proper functioning of the receiving equipment depends on setting the desired date and time. To correctly specify the data, you need to implement the following scheme:
These actions will allow you to synchronize the signal and improve the delivery of teletext. They will also contribute to the smooth operation of TV guides.
If errors or technical failures occur, the subscriber can contact the provider’s support service.
There are many reasons that prevent TV viewers from safely using satellite television and watching their favorite programs. Quite often, subscribers see an unpleasant message that the list of regions is unavailable. Tricolor is not always able to provide a high-quality signal that would allow users to safely receive all paid services.
But before you scold the satellite company, it’s worth thinking about the real causes of the problem, because often the source of difficulties is not a weak signal, but equipment malfunction. Therefore, when faced with a sign about the inaccessibility of a region, you should seriously think about the cause of the trouble that occurred and try to solve it yourself. Sometimes such actions allow you to save both the time required to wait for the telemaster and the money that will be spent on his help.
The receiver does not turn on from the remote control
If there is no response to the remote control buttons, you should perform the action using the button panel on the receiver itself. If the actions are performed, then the receiver is functioning. After changing the batteries in the remote control, check the control using the remote control again. Operation did not resume - you need to use a different remote control.
Craftsmen can try to check the functionality of the remote control in another way. A mobile phone camera is used for this. Point the remote control LED at the camera that is turned on.
Point the remote control at the camera.
While looking into the camera and pressing buttons at the same time, monitor the LED indication:
- Steady flashes indicate that the remote control is working properly;
- Unstable lighting intermittently is due to the board not functioning;
- Lack of indication means the remote control is faulty or the batteries are low.
If after changing the batteries the LED does not start blinking, then you should buy a new remote control.
Repairing a device with rare glows is carried out by disassembling the case and cleaning the surface of the board with a damp cloth, soapy water and a dry rag. After all cleaning operations, dry the parts and assemble the remote control. If the flash does not become constant when viewed through the camera, a new device is required.
When setting up Tricolor TV, the list of regions is not available - problem options
When starting to consider possible causes of difficulties, it is worth focusing on situations where trouble occurs immediately after changing the receiver. The use of new, more modern equipment can lead to difficulties in setting up the equipment and catching the signal.
Most often, participants in a technology exchange program encounter a similar problem. At the same time, connecting the old receiver instantly restores the broadcast, which makes the situation more absurd and its solution more difficult.
But, if you seriously think about what is happening, it turns out that the source of trouble is on the surface. The new device is much more functional and reliable than the old one. It contains more features and gives subscribers more options. In addition, the resulting technology usually supports higher quality signal reception. All this requires the use of large powers, which are not supported by the converter on the antenna. Therefore, as soon as a better and more powerful converter is installed, access to TV will be restored.
Technical malfunctions of the receiver
The receiver is the link responsible for receiving the signal and transmitting the video stream. Technical components of the device may break down or software problems may occur. The receiver itself has a warranty period (1 year), during which specialists must repair the device.
If a breakdown occurs after the end of the warranty period, you can carry out independent diagnostics or send it to a service center. Problems that often occur are displayed as errors on the TV screen or the device itself. Please note that the following errors are specific to some models:
- DRE 5000, 7300, 5001;
- DRS 5003;
- GS 7300, 8300, 8300N, 8300M.
Instructions for setting up the channel list for HD 9303, HD 9305 receivers.
To correctly display the list of TV channels, follow these steps:
1. Press the “Menu” button and select “Search for Tricolor TV channels”.
2. On the region selection screen, select the region that suits you. There will be 3 regions available for selection: “Main”, “Moscow +0 hours.” and “Moscow +2 hours.”
Attention! You must select one of two regions - “Moscow +0 hours.” or “Moscow +2 hours.” - depending on the region of your residence. In the first case, all TV channels will be broadcast according to Moscow time, in the second, some TV channels will be broadcast with a time shift of +2 hours from Moscow time.
When you select the “Main” region, one information channel will be saved in the channel list.
3. Wait until the search for TV channels is completed and save the found TV channels.
The receiver does not turn on after a software update
Updated software may not install correctly. As a result, the receiving device will not turn on. The subscriber must follow the reset steps:
- In the receiver Menu, find and open the “Settings” section;
- Select the “Reset” command;
- After confirmation, wait for the end of the process and reboot the receiver;
- When turning on, you may need to enter an access code - then enter the combination “0000”;
- After logging in, the necessary parameters are set (language, time, location);
- To install TV channels, you need to perform a search operation and save the changes.
Calling a company specialist
When purchasing digital TV services, ask an employee not to deliver and hand over the equipment to you, but to ensure that it is properly configured and installed correctly. Make sure the system is functioning properly. Check the operation of the equipment in the presence of a company employee. Call a specialist through the support service who will quickly find the source of the problem and fix it. The company has a positive reputation and has been operating for more than 20 years. Tricolor TV is interested in good quality service and customer comfort. If the list of regions is not available, consultants will explain what to do.
On July 20, 2021, changes were made in broadcasting aimed at dividing regional TV channels into appropriate lists and designed to make viewing these TV channels more convenient.
This page contains instructions for all receiver models (see below on the page).
What to do if none of the methods helped
After diagnosing the equipment and eliminating all possible breakdowns, you can contact the service center. First you need to remember about the warranty, if it is still valid. Typically the period is 12 months. Once you have found the warranty card, contact your nearest service center. After a quick diagnosis, employees will be able to repair the broken part free of charge.
When the warranty has already expired, you will have to take the product for service under normal conditions. Specialists can open the case and identify the cause. After which they will offer to carry out repair work, voicing the cost of spare parts and repair procedures. It is worth considering that a long service life of the receiver leads to the exhaustion of the intended resource. Therefore, for greater savings, it is better to buy a new receiver than to repair an old receiver.
