Do-it-yourself tricolor receiver repair 8306

In detail: do-it-yourself tricolor receiver repair 8306 from a real master for the site my.housecope.com.

Click! gs 8306 after update, repair!

Gs 8306 stopped turning on completely after the update. Maybe both LEDs are lit on the display and then the receiver hangs. All this suggests that the receiver has lost boot sectors, it simply broke. If, as a result of the diagnostics, it was confirmed that the matter was in the flash memory, then we are doing the procedure to restore our receiver to working condition.

We disassemble the receiver, we prepare our main board for repair.

gs 8306 stopped turning on after the update.

If necessary, we clean the main board from dust and other contaminants.

We take a flux, apply microcircuits to the contacts. All contacts must be covered in order to make it easier to remove our microcircuit from the main board.

We turn on the soldering station, take a hair dryer and begin to warm up the element that we need to remove. In this repair, we are interested in W25Q128BV.

After we removed the microcircuit from the main board, we proceed to programming. To do this, we need a programmer and a corresponding socket - an adapter.

We insert into the programmer, turn on the program. We look for the device to recognize our flash drive.

programming W25Q128BV on chipprog 48

If everything is in order and the contact is good, then you can upload a new dump to the memory of the microcircuit. ChipProg-48 during operation will show what state it is in, if there is an error, the red indicator will light up.

ChipProg-48 programming 8306

After everything has been flashed, we mount the microcircuit on the board. First we apply the flux.

Next, we warm up the board with a hairdryer, wait until the solder turns into a liquid state. If necessary, position the chip on the board.

We do 8306 after an unsuccessful update.

When everything is soldered, we wait until everything cools down. We take the front panel, connect the power. Our receiver is starting to work! We check our receiver in all modes.

If you still have questions, you can watch our video, in which we showed everything clearly! The main thing - remember, if you are not confident in your abilities, then take the broken receiver to the service center!

Good day. Nikolai is writing to you from Tolyatti. Faced the same problem as you describe in the article. For the solution, there is not enough file with the latest firmware, 1.9.160. I found only version 1.2.001 on the Internet. If you don't mind, please email me, thanks in advance. Yes, the article is extremely useful, because the problem is becoming widespread ... Many thanks for the information.

Best regards, BNikolai, Togliatti

I read reviews about firmware 1.9.160 on your resource ... and well, it’s far to hell. You could not throw off the previous version instead of it. Don't take it as arrogance.

Today we have a GS 8306 receiver for repair.

This model, in my opinion, is not very successful. There is no display.
Two LEDs indicate on and off.
There is a button for switching TV outputs on the remote control, the HDMI output and video output are not parallel and are switched from the remote control, and this creates inconvenience.
The problem with this receiver is that it won't turn on.
The first step is to check the nutrition.
There are many controllers on the board, each controller has a small choke (voltage is signed for all, they must match when checked by the tester).
Tester check the voltage of each controller.
To do this, we apply the black “probe” of the tester to the tuner, and apply the red one in turn to each throttle.
The measurements are displayed on the tester screen.
In this case, everything is fine.

Here is a 16 megabyte memory dump.
When jumping the DataSheet, it turns out that the data output is leg 15.
We check with an oscilloscope whether the processor on this leg is reading data from the flash card.
We put the “probe” on the 15th leg and the data packets are read.
The processor reads the flash drive, which means the processor is good.
Next, we solder the flash, and flash the tuner.

In this way, you can repair the GS8306 receiver.
You can watch a video instruction with a more detailed guide below.

We will be glad if this manual is useful to you.

If the message is displayed when inserting a smart card: “Smart card is incorrectSmart card is not inserted“

, then the smartcard controller failed most quickly on the receiver board TDA8024 .

If such garbage occurred and the flashing did not help, then the most likely problem is iron:

In my case, the receiving module turned out to be the culprit:
(not an isolated case, with this problem - through one and all with this disease)

And when it was opened, flooding and corrosion were found:

Plus, after removing the module, the track was damaged:

Module includes : m88ts2022 (DVB-S2/DVB-S/ABS-S tuner) and M88DS3103 (DVB-S2/S demodulator)

Accordingly, I had to replace the module from the donor. and throw the track mgtf - om.

Only the radio works (as an option), does not reset to factory settings, freezes and turns off, is not flashed via USB, is not updated in any way.

Hello, today we will try to fix the Tricolor TV receiver with our own hands. Many faced such a problem when the warranty (usually it is 12 months) ended, and the receiver suddenly failed. A new one is expensive, and in most cases, repairs will not be difficult and will cost a penny, if you are at least a little friends with a soldering iron, the main and most common malfunctions can be easily fixed by yourself. Consider such a repair using the example of another receiver from the Tricolor TV company GS-8300 N. I must say that the device is not of the best quality, and the money that Tricolor TV takes for it, of course, is not worth it. But, nevertheless, the number of subscribers is large and not all of them work for a long time and properly.

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 cable short circuit protection, 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 juggling of the mains plug from the outlet and turning the toggle switch on and off does not help 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, once again make sure that the warranty period has exactly 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.

An electrolytic or oxide capacitor at the input often dries up and fails, which is also a malfunction, not everyone can find such a breakdown either, you need to have at least the initial level of a radio amateur. Usually failed capacitors have a yellowish appearance, or a small brown speck on the circuit board at the base of the legs. Also, the serviceability of a capacitor can be determined by comparing its nominal and measured capacitance.

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, but 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 it 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, respectively, everything else is de-energized. The transistor cost me 28.5 rubles. By replacing it with a soldering iron, I fixed the problem and the receiver is back in working order. I must say such a breakdown is quite rare, usually everything ends with a fuse.

A very common malfunction is a firmware rally. The firmware often flies, the evidence of this is usually the complete freezing of the receiver. In this case, "flashing" will help. I also want to say about another reason for the malfunction, which may arise due to poor-quality installation. Water in cable. If the outer insulation of the cable is broken, then water from precipitation can get inside and easily enters the receiver through a hose, sometimes flooding all its insides. The condition of the cable must be monitored throughout the life of the device.

Electronic devices surround us everywhere: on the street, at work, at home. With the rapid growth and availability of satellite television to the general public, a wide range of satellite equipment has appeared for 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 cause us to feel the loss of our favorite thing.

You should not despair - for this 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 drops, failure of various components, wear and tear of the equipment itself from its venerable age, one can also note the incompetence of the owners themselves, for example, incorrect replacement of software in satellite and cable receivers.

The failure of the power supply is perhaps the most common type of malfunction of digital terminals. It arises for various reasons: poor-quality power supply (see photo), poor-quality radio components are used, especially this is de facto in Chinese technology.

Also here can be attributed a violation of operation, dust, dirt, as a result of which the thermal regime is not correct (see photo).

The service center is a structural unit within the company. He is entrusted not only with the repair and maintenance of products sold by our company, but also with the repair (including warranty) of satellite equipment of other companies. Our customers are not only individuals - users, but also equipment dealers who seek to save their customers from the problems associated with the repair and maintenance of receivers. A flexible policy towards corporate customers allows us to provide proper service and satisfy the interests of all customer groups. This is more than 1000 pieces of equipment per month. Of course, the professionalism of the employees, the equipment of the service center with professional equipment, tools and technical documentation make it possible to carry out such large volumes. Therefore, our service center performs repairs of high complexity: for example, the replacement of processors in BGA packages. The repair takes place as soon as possible.

The supply department, in addition to its main function - the purchase of equipment, also deals with 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 takes place according to the following criterion: the quality of the parts is in the first place, their price is in the second place, 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. The work performed is guaranteed.

Of course, unforeseen moments happen - for some reason, repairs are delayed. This usually happens due to the lack 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 are trying to find some acceptable solution together with the client, taking into account his wishes, combined with our capabilities.

At autopsy, the following were found out of order:
– mains capacity C5 – 47µFx400V
– Q1 – CS2N60F
– R8, R11, R13 – 3 ohm each (size 1206)
– R9 – 47 Ohm (1206)
- U1 - it was not possible to determine its type by the marking on the case.

According to the table for identification and selection of analogues https://my.housecope.com/wp-content/uploads/ext/2561/ic_power/, the last part was replaced by SG6848 with minimal interference with the factory circuit.
We dismantle: (circled in red in the photo)
– U1
- R8, R11, R13 - 3 ohm (1206)
- R3, R6 (one of them is possible) - 1 MOm (1206)
– C3 – 68nF
- R25 - 3.6 kOhm (0805)
– R26 – 10 kOhm (0805)
Install:
– instead of U1 – SG6848
- instead of R8, R11, R13 - one resistor 1.8 Om x 0.5W (usual output, because I did not find the required value of smd))
- instead of C3 resistor 100 kOhm (1206)
- instead of R26 resistor 33 kOhm
- instead of R25, we select a resistor in the range of 10-12 kOm, controlling the voltage 3V3 at the VD8 cathode. I settled on 11 kOm, U=3.36V (at 10 kOm U=3.28V, at 12 kOm U=3.41V)

Instead of the burned out Q1, SSS4N60B was installed (TO-220F case)

On Telesputnik they posted a power supply diagram.

There are inaccuracies:
1. The lower terminal of the primary winding must be connected
to the connection point of anode D6 and drain Q1
2. Position designation C2 and C3 is incorrect. C3 must be connected to the 3rd pin
U1, C2 to the 4th pin of U1.
3. Rating C3=68nF
4. There are two capacitors C1 in the diagram
5. Missing C12
6. Primary land is labeled in the same way as secondary land.
7. Missing C8
8. Q2 - MOSFET NTD14N03R
9. Rating C11=2200pF
10. Type D8=SR560
11. The positional designation of U3 and U4 is incorrect - they must be swapped.
12. Rating C5=47µF

The receiver turns on, there are 18 volts on the LNB. There is no video signal, it gets very hot (does not hold a finger) stv 6419 .. because of it there may not be a video? no other point? (in the sense there is no more video signal from where?) the receiver switches channels ..

Receiver GS 8300N no video and audio signal through scart to TV, channels are switched on the receiver panel.

the video signal from the STi5119ALC processor comes in, you can check it with an oscilloscope at a 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, there is no output to R91 from it, the culprit is no 12 volts on the board, respectively, there is no power supply + 12V on the 3rd leg of STV6419, a 12 volt D3 zener diode is faulty near the power connector

There was such an answer: if you use only a composite video signal, most likely you can simply throw it away (replace it with a jumper). Where to put the jumper? if this is the right advice..

Faulty VD3 (VD3 zener diode at 12 V) on the motherboard next to the power connector.

Zener brand and parameters:

Power + 12V to the 3rd leg STV6419.
In a chain: XP5 connector 9th leg -> R81(300 Om) + Zener diode VD3 (12V) = stabilizer + 12V -> L3 -> 3rd leg STV6419.

Zener diode analogue:

VD3 STV6419 similar zener diode (SMD) was not found. I put a 0.5 watt glass zener diode the size of a diode kd522 . While the flight is normal.

If replacing the zener diode did not help:

After a thunderstorm, 6419 swelled. After the replacement, the image did not appear, but when checking the strapping, two resistors turned out to be open, R91, R95. Replaced it and everything worked.

One more problem:

And yet, instead of 13, 18 Volts, 24V went to the LNB. Needed a replacement DA1 (LM317T). And that's it, the flight is normal

The same situation with the GS-8304 receiver:

After 5 years of work, the GS-8304 suddenly stopped broadcasting, although the indication is working properly.
The zener diode has broken into a short circuit. Zener brand MMZE5242B.

Satellite TV is evolving with every update and with every new device. Each user of satellite television from time to time encounters problems and errors in the operation of their receivers or other components. This may be due to various factors. For example, older models may fail due to a long operating time.Despite their quality and reliability, devices can break down due to unsatisfactory weather conditions, electrical problems or misuse. Let's consider this in more detail.

Among the causes of breakdowns of models GS8306, GS8300, DRS-5001 are the following:

the receiver does not start;
the timer flashes on the display of the set-top box at startup;
on the display of the set-top box there is only a non-flashing timer;
on the display of the console is the inscription "boot";
on the display of the set-top box there is an inscription of the error ER31;
on the TV display an error when you turn on "Short circuit!" or "Check antenna cable".

In the case of the last error, you can carry out diagnostics yourself to clarify the cause of the malfunction. When the wire was disconnected, the error inscription disappeared, the problem of the malfunction lies in the satellite converter or the antenna cable. Next, you need to check the wire in case of a short circuit. If it is not there, there is an error in the satellite converter. But, if the TV still signals an error, the problem is in the tuner.

These types of breakdowns include other representatives of the MPEG-2, MPEG-4 and Full HD set-top box series. No need to prematurely go to the store for another device, because the purchase will definitely cost a lot. It is recommended to contact service center for qualified help, or repair the receiver with your own hands, if you have the necessary skills.

Diagnostics shows that often the accessories of the set-top box fail:

firmware - this can be detected if you see errors on the display;
Tricolor receiver power supply - when the receiver does not turn on or the timer flashes;
motherboard - only the timer is displayed or with an ER error

However, satellite TV users may experience picture, sound or signal problems. This also happens due to problems with the receiver. They include the following:

breakdown of the satellite converter;
the antenna cable is damaged;
failure of the tuner block;
weak signal due to obscuring trees;
unsatisfactory weather conditions.

The reasons also include channel broadcast frequency changes or even a whole package of channels or malfunctions in the operation of the satellite, to which the service center has nothing to do.

First of all, you don’t need to start repairing Tricolor receivers yourself if you are not 100% sure what and how you are doing. If the warranty period is valid, it is best to entrust the repair of the Tricolor satellite receiver to a specialist. But, this is possible if there is a warranty card, purchase receipt, customer's signature. The repair warranty may be voided if:

receiver operation during power surges;
damage to the seal or the integrity of the structure;
errors when switching, connecting cables or incorrect programming;
the receiver was not installed by the installer, and this led to a breakdown during operation;
the client violated the terms of use;

All this must be followed if the client wants to repair his receiver in the future.

Repair of the Tricolor TV receiver is as follows:

replacement of the motherboard;
changing the power supply;
module replacement;
flashing or reinstalling software.

In the event of a motherboard failure, it is most often recommended to buy a new and more modern version of the set-top box, because repairing the board will cost almost the price of a new receiver.

For example, there are a number of errors and correction options typical for each type of device. The peculiarity of the repair of Tricolor GS8300 receivers depends on the alteration of the power supplies, because the devices are not highly resistant to voltage surges. For the GS 7300, a typical problem was overheating, which caused the diode bridge or microcircuit to break. Also, the power supplies for the Tricolor receivers sparked after long work, so they often had to be changed. The most optimal model GS8306 also had typical problems. For example, overheating when watching channels for a long time.

Firmware Programmer for Gs 8306.

flashing the GS 8305 satellite receiver after an unsuccessful firmware update via satellite. Described in the video.

Recently, more and more customers of the company Kirovsat in Kirov, after purchasing and installing a Tricolor satellite television set in Kirov and connecting to the Tricolor operator, they began to address one single question about the operation of the GS 8306 HD receiver: “What should I do, I have no picture on the TV screen, but the GS 8306 HD Tricolor receiver works, and responds with an indicator signal when pressing the keys on the control panel?

For help in solving the problem, you can contact our Kirovsat company in Kirov, or figure it out on your own by reading the article below.
In order to get out of this situation, let's plunge into the technical part of the GS 8306 HD Tricolor receiver and determine its main operating modes, having studied which you can easily determine what manipulations need to be done in order to enjoy watching channels again using the GS 8306 HD Tricolor receiver.

And so, the GS 8306 HD Tricolor receiver is a technically complex device, to start working with which, it is advisable to study the instructions attached to the satellite equipment kit.

As you noticed, the reverse side of the GS 8306 HD Tricolor receiver has 2 outputs: RCA output "tulip" and HDMI, to switch between which, on the remote control of the receiver, there is a button "input signal" located in the upper left part of the remote control .

Some users of GS 8306 HD Tricolor receivers connected to a TV via RCA or HDMI output mistakenly press the “input signal” button when switching channels, as a result of which the GS 8306 HD Tricolor receiver switches to another output and the image on the TV disappears.

As a rule, older people start to panic and, in order to return the receiver to normal operation, they begin to sort through all the keys on the remote control of the GS 8306 HD Tricolor receiver, which, of course, does not lead to the desired result. There are also subscribers of the Tricolor operator who, in such a situation, take their GS 8306 HD Tricolor satellite receiver to one of the service centers located in Kirov and other regions of Russia.
In this situation, we would advise you not to rush, and not to blame our company Kirovsat in Kirov for the sale, as it seems to you at first glance, of low-quality goods, but to carefully look at the operating mode of the indicator light, which is located on the left, on the front panel of the receiver and illuminates power button on the receiver GS 8306 HD Tricolor.

The following is a list of operating modes of the light indicator of the GS 8306 HD Tricolor receiver with an explanation of the operating mode in which the receiver is located and options for your actions to bring the receiver into working condition:

1. Indicator light is off – the receiver is turned off (to turn it on, press the “on” button on the front panel of the receiver)
2. The indicator light flashes alternately – the receiver is off, in standby mode (to turn on, press the “on” button on the remote control of the receiver)
3. One top light is on in the indicator light – the receiver is turned on, the signal is taken from the RCA output “tulips” (to switch to the HDMI output, press the “input signal” button once)
4. Indicator light is fully on (not blinking) - the receiver is on, waiting for switching between RCA and HDMI outputs (do not press anything, wait until one of the lights lights up: top or bottom)
5. There is one lower lamp on the indicator light – the receiver is turned on, the signal is taken from the HDMI output (to switch to the RCA output, press the “input signal” button once)

If both indicators on your receiver are lit for a long time and the GS 8306 receiver does not respond to the remote control in any way, the first step is to turn off the receiver from the power supply for 2-3 minutes. If the problem persists after turning it on, try flashing the receiver from an external USB drive. How to do this is described in the article “Firmware update GS 8306 Tricolor”.

Thus, you have become familiar with all the operating modes of the GS 8306 HD Tricolor receiver, and we hope that a small note from our Kirovsat company in Kirov will help you eliminate cases of worry about the performance of your receiver.
