It’s hard to imagine a subscriber who would be happy when problems arise and an interesting broadcast is interrupted. That is why users are only interested in 2 questions that they would like answers to when the message “error 0” appears on the screen on Tricolor TV: what does it mean and how to fix it.
Both mentioned issues are extremely related, since it will not be possible to restore broadcasting without understanding the reasons for its interruption. It is also true that untrained people can only find the source of problems by trial and error, sequentially checking every possible malfunction and trying to restore the broadcast.
It is also worth considering the fact that sometimes difficulties arise due to the actions of the provider (preventative work) or factors independent of either party. This means that the client will not be able to restore the television on his own, and therefore he will just have to wait until the broadcast is restored automatically. But before that, you need to eliminate the main causes of the error and try to understand what happened.
Channels disappeared on Tricolor TV
There are several reasons why subscribers lose access to the system:
- External conditions. Communication with the satellite may be disrupted in unfavorable weather conditions. In this case, the signal may be interrupted or completely absent. The reason is the small diameter of the signal receiver. Most often, standard antennas with the same dimensions are used. To obtain a higher quality broadcast, it is recommended to purchase additional equipment.
- Poor system setup. The installation procedure should be trusted to experienced professionals. If the user decides to carry out the procedure independently, then there is a high risk that the system will not function correctly. This may be due not only to interference in the resulting image, but also to its complete absence.
- Obstacles on the ground. Some buildings or trees also interfere with the broadcast. In this case, the only option to improve the signal quality is to reinstall the antenna.
There may be no signal if the plate is icing. Please note that in some cases the cause is technical work being carried out on the satellite.
Bad antenna signal
An antenna unit that is placed incorrectly or accidentally rotated by wind or impact will no longer transmit a sufficiently strong signal to the receiver. As a result, the latter does not find all channels or does not see them at all. In this case, an error message appears on the device screen.
The antenna condition is monitored as follows.
- You must make sure that there is no thick layer of dirt, bird droppings, ice, or snow on the deflector. If present, they are carefully removed.
- There should be no large objects in the deflector.
- The satellite reception line must be free of obstacles in the form of branches, drying clothes, and open window frames.
If visually everything is in order, you should check the signal intensity at the receiver input . To do this, call the information banner. On most receiver models, this is done by sequentially pressing the red and blue buttons on the remote control. The system will display reception indicators at the bottom of the screen. Their readings should not be less than 70%, ideally 100 for the left and 75 for the right.
The antenna can be adjusted manually. This is done according to positioning tables for a specific city, where the angle of vertical inclination and horizontal rotation relative to the direction to the north is indicated. If such data is not at hand, the work can be done manually. To do this, turn the deflector little by little. When pausing, you need to monitor the changes in the levels of indicators on the TV screen.
Important! If the system shows that there is no signal coming from the antenna unit, you should seek help from specialists. Most often, this situation means that the converter has failed. It needs to be repaired or replaced entirely.
Why are some channels not shown on Tricolor?
If there is no signal at all, we are talking about mechanical damage to the external equipment. What could be the reason for the lack of access to some channels?
If only today Tricolor does not show several channels, then the reason may be as follows:
- No additional fees for some channels that are provided to subscribers who have paid for an additional subscription.
- The access card is not activated or is missing from the receiver.
- Equipment malfunction, which requires additional diagnostics.
What to do
What to do if there is no Tricolor TV signal at all? In this case, you need to call a company specialist who will carry out diagnostics and provide several options for correcting errors. If we are talking about technical malfunctions, then there is a need to replace equipment or reset system settings. If you do not have the opportunity to call a technician to your home, you can reset the settings yourself, returning them to the factory settings. After this, you should set it to automatically search for channels. In most cases, these actions are sufficient to restore access.
The following considerations should be taken into account:
- The set-top box responds to the OK button - install a satellite dish of a larger diameter or wait for weather conditions to improve. Review the settings and, if necessary, adjust them yourself or under the guidance of a specialist. Try to adjust the list of TV channels by manually editing the broadcast indicators. Check the integrity of the cable and the serviceability of the satellite converter and, if necessary, replace them.
- The set-top box does not respond to the OK button - the message in this case is sent not by the receiver, but by the TV. The reason most often lies in switching the wrong input on the television receiver. The activation of the input can be adjusted using the Source switch. When using the GS8306 model, the lack of signal is due to the inconvenient location of the switch, for example when cleaning. Equipment shutdown occurs. After switching the indicator, the system starts working properly again.
We should not forget about reasons such as the lack of activation of the Tricolor TV subscription. You can carry out the procedure by phone, through your personal account and in the company’s office. If the problem occurs during an active subscription, then factors such as the visibility of the SMART card and the correct operation of the built-in module should be examined.
What to do if error 0 on gs 8300n, gs 8302, gs 8304, gs 8306 receivers
When Tricolor displays error 0 on gs 8304, gs 8302, gs 8306 or other receivers, you need to check:
- does the set-top box support displaying channels in HD (a list of similar channels included in the “Unified” package is available on the website);
- make sure that this format is supported by the TV;
- check to see if an update is required.
To check for updates, just go to the receiver menu and find the section describing the current software version. Then visit the provider’s website and look at the pages indicating the current version of the program. If necessary, users should flash their equipment. To do this, you need to install the required update yourself or start this process automatically, having previously visited the information channel.
Additional Information
Please note that to improve the quality of service, the satellite and digital television operator Tricolor TV periodically improves the software.
In order to take advantage of these improvements, each subscriber must update the system monthly. To do this, you need to download additional software on your computer and via USB, using removable media to update the system. This procedure allows you to view channels, including TNT in HD quality.
When using Tricolor TV, errors such as lack of signal often occur. Only info channels can be accessed. In some cases, there is no viewing access at all. In 2021, there were no failures caused by the operator.
In order to eliminate the possibility of such situations occurring, you should use the equipment correctly, following the recommendations of the broadcast service provider.
If you have any difficulties setting up the equipment, please contact the call center operator by number. An experienced employee will answer any information question and help solve a technical problem by providing step-by-step guidance.
Hello, today we will try to fix the Tricolor TV receiver with our own hands. Many people have encountered this problem when the warranty (usually 12 months) has expired and the receiver suddenly breaks down. A new one is expensive, and in most cases, repairs will not be difficult and will cost pennies, if you are even a little familiar with a soldering iron, the main and most common faults are easy to fix yourself. Let's look at such a repair using the example of another receiver from the GS-8300 N. It must be said that the device is not of the best quality, and the money that Tricolor TV charges for it, of course, is not worth it. But, nevertheless, the number of subscribers is large and not everyone has everything working for a long time and properly.
Power supply fault:
The main and most common malfunction of all receivers is a malfunction in the power supply circuit and voltage conversion. Also, the modulator often fails due to a short circuit in the coaxial cable from the LNB, although the latest models have good protection against short circuits in the cable, when triggered, the voltage supply to the converter simply stops until the short circuit is eliminated.
And so, our receiver does not show any signs of life, the indicators on the front panel display do not light up, and no amount of pulling the power plug from the socket and turning the toggle switch on and off helps us (at least this was the case with the device, an example of which is given in this article) . The first thing we do is pull out the plug from the network and remove the top cover; we need to get to the electronic filling of the device. And here it is important to remember one thing, namely the warranty seal, which we will certainly break if we remove the cover. Therefore, make sure once again that the warranty period has definitely expired, and no one will repair it for you under warranty. If the warranty is still valid, I advise you to take the receiver to a service center and entrust this matter to a specialist.
Opening the lid, we see printed circuit boards with many components connected to each other by wire buses. Below are photos describing some of the devices on the board. First of all, we are interested in the power board; it is not difficult to distinguish it by the transformer installed on it and the power supply cable. And the first thing we pay attention to is the fuse. It is usually installed at the beginning of the chain. The fuse will not necessarily have the shape you are familiar with (a glass capsule with a thin conductor inside), for example, in my case the fuse is enclosed in a small plastic box, and in order to get directly to the fuse itself, the cover of this box must be removed. This is done very simply, for example with tweezers. Having reached the fuse, we check it with a tester or multimeter for a break. If the fuse burns out, which by the way happens very often, we go to a radio store, buy the same one, change it and that’s it. If this is not the case, we check the parts further along the chain. Often the transformer itself fails; we can detect such a malfunction by measuring the voltage on the secondary winding. I must say that not everyone can replace the transformer, if so, then it is better to take the receiver to a workshop, but if you are confident in your abilities, then go ahead, for example, it will not be difficult for me.
Receiver inside:
The electrolytic or oxide capacitor located at the input often dries out and fails, which is also a malfunction; not everyone can find such a breakdown either; you need to have at least an initial level of amateur radio. Typically, faulty capacitors will have a yellowish appearance, or a small brown spot on the board at the base of the legs. Also, the health of a capacitor can be determined by comparing its nominal and measured capacity.
The receiver uses direct current, which is rectified from the AC network using a diode bridge. Problems with the diode bridge also happen. Diodes are very easy to check; the main function of a semiconductor diode is to pass current in one direction and not in the other. In my case, the transistor of the primary winding of the transformer turned out to be faulty; it is not difficult to find; it usually has a radiator for heat removal. I determined the malfunction of the transistor by measuring the voltage at its emitter, it was absent there, the primary winding was not powered, and therefore everything else was de-energized. The transistor cost me 28.5 rubles. Replacing it with a soldering iron, I fixed the fault and the receiver is in working order again. I must say that such a breakdown is quite a rare occurrence; usually everything ends on the fuse.
A very common problem is a firmware crash. The firmware often crashes, which is usually evidenced by the receiver completely freezing. In this case, "" will help. I would also like to say about another cause of malfunction, which may arise due to poor-quality installation. Water in the cable. If the external insulation of the cable is broken, then water from precipitation can get inside and easily enter the receiver like a hose, sometimes flooding all its insides. The condition of the cable must be monitored throughout the entire service life of the device.
Electronic devices surround us everywhere: on the street, at work, at home. With the rapid growth and accessibility of satellite television to the masses, there is now a wide range of satellite equipment available to the public. These are satellite receivers, conditional access modules, antennas, converters, etc. Whether we like it or not, sooner or later breakdowns happen to them, which make us feel like we have lost our favorite thing. There is no need to despair - for this purpose there are service centers that you can contact and they will help you bring your equipment back to life.
Equipment breakdowns occur for various reasons - voltage surges, failure of various components, wear and tear of the equipment itself from its venerable age, you can also note the incompetence of the owners themselves, for example, incorrect replacement of software in satellite and cable receivers. A power supply failure is perhaps the most common type of malfunction of digital terminals. It occurs for various reasons: poor-quality power supply (see photo), low-quality radio components are used, especially this is de facto in Chinese technology. This also includes improper operation, dust, dirt, and as a result, incorrect thermal conditions (see photo).
A service center is a structural unit within a company. He is responsible not only for the repair and maintenance of products sold by our company, but also for the repair (including warranty) of satellite equipment from other companies. Our clients are not only individual users, but also equipment dealers who strive to relieve their customers from the problems associated with the repair and maintenance of receivers. A flexible policy towards corporate customers allows us to provide adequate service and satisfy the interests of all customer groups. This is more than 1000 units of equipment per month. It is, of course, possible to carry out such large volumes due to the professionalism of the employees, the equipment of the service center with professional equipment, tools and technical documentation. Therefore, our service center carries out highly complex repairs: for example, replacing processors in BGA cases. Repairs take place in the shortest possible time. The supply department, in addition to its main function - purchasing equipment, also provides for the needs of the service center, purchasing components necessary for repairs. And here it is worth noting that the selection and purchase of components for repairs occurs according to the following criterion: the quality of the parts comes first, their price comes second, but due to the large volumes of supplies of parts, the price ultimately remains low. All orders are processed electronically and registered in the database. This makes it easy to track the various stages of the repair process. A guarantee is provided for the work performed. Of course, unforeseen moments happen - for some reason the repair is delayed. This usually happens due to the absence of some scarce radio component. Sometimes repairs require a complete replacement of the motherboard, and this repair part is not always available. In this case, we try to find some acceptable solution together with the client, taking into account his wishes, combined with our capabilities.
The receiver died after a power surge.
Upon opening, the following were found to be faulty: - network capacitance C5 - 47µFx400V - Q1 - CS2N60F - R8, R11, R13 - each with a nominal value of 3 Om (size 1206) - R9 - 47 Om (1206) - U1 - determine its type by markings on the case failed. According to the table for identification and selection of analogs https://remont-aud.net/ic_power/, the last part was replaced with SG6848 with minimal intervention in the factory circuit. Let's dismantle: (circled in red in the photo) - U1 - R8, R11, R13 - 3 Om (1206) - R3, R6 (you can use one of them) - 1 MOm (1206) - C3 - 68nF - R25 - 3.6 kOm ( 0805) - R26 - 10 kOm (0805) We install: - instead of U1 - SG6848 - instead of R8, R11, R13 - one resistor 1.8 Om x 0.5W (regular output, because I didn’t have an SMD of the required value )) - instead of C3 there is a 100 kOm resistor (1206) - instead of R26 there is a 33 kOm resistor - instead of R25 we select a resistor in the range of 10-12 kOm, controlling the voltage 3V3 at the cathode VD8. I settled on a nominal value of 11 kOm, U=3.36V (at 10 kOm U=3.28V, at 12 kOm U=3.41V) Instead of the burned-out Q1, an SSS4N60B (TO-220F case) was installed
GS-8300 power supply diagram
Telesputnik posted a power supply diagram. There are inaccuracies: 1. The bottom terminal of the primary winding should be connected to the connection point between the anode D6 and drain Q1 2. The position designation of C2 and C3 is incorrect. C3 should be connected to the 3rd pin of U1, C2 to the 4th pin of U1. 3. Nominal value C3=68nF 4. There are two capacitors C1 in the diagram 5. C12 is missing 6. The primary ground is designated in the same way as the secondary one. 7. Missing C8 8. Q2 - MOSFET NTD14N03R 9. Rating C11=2200pF 10. Type D8=SR560 11. The position designation of U3 and U4 is incorrect - they must be swapped. 12. Rating C5=47µF
If the AV output does not work
Question:
The receiver turns on, there is 18 volts on the LNB. There is no video signal, it gets very hot (can’t hold your finger) stv 6419..could there be no video because of it? Is there no other point? (I mean, there’s nowhere else to get a video signal from?) The receiver switches channels..
Receiver GS 8300N there is no video and audio signal through scart to the TV, channels are switched on the receiver panel.
Solution:
the video signal from the STi5119ALC processor arrives, you can check it with an oscilloscope at the test point opposite the capacitor C117, then it comes to the resistor R87 and is transmitted to the capacitor C129 and then goes to the STV6419 chip; on the 3rd leg of STV6419, the 12 volt zener diode D3 near the power connector is faulty
There was this answer: if you use only a composite video signal, most likely you can simply throw it away (replace it with a jumper). Where should I put the jumper? if this is the right advice...
VD3 (VD3 12 V zener diode) on the motherboard next to the power connector is faulty.
Zener diode brand and parameters:
Power supply +12V to the 3rd leg of STV6419 ... Along the chain: connector XP5 9th leg -> R81 (300 Om) + zener diode VD3 (12V) = stabilizer +12V -> L3 -> 3rd leg of STV6419.
Zener diode analogue:
I couldn’t find a similar VD3 STV6419 zener diode (SMD). I installed a 0.5 watt glass zener diode the size of a CD522 . So far the flight is normal.
If replacing the zener diode does not help:
After the thunderstorm, 6419 swelled. After the replacement, the image did not appear, but when checking the wiring, two resistors turned out to be broken, R91, R95 . Replaced it and everything worked.
One more problem:
And yet, instead of 13, 18 Volts, the LNB received 24V. Replacement of DA1 (LM317T) . And that's it, the flight is normal
The same situation for the GS-8304 receiver:
After 5 years of operation, the GS-8304 suddenly stopped broadcasting, although the display was working properly. The zener diode broke through to short circuit... Zener diode brand MMZE5242B...
