Repair GS-8300

At this article, we repair the “tricolor” receiver with our own hands. This problem is most often blamed for the fact that the warranty term has expired, and the priymach is known to be angry. It is expensive to buy a new receiver, to carry it to the service center - then, for a long time, indulge yourself in watching the satellite TV. Even in rich situations, the breakdown of the outbuilding can be repaired independently, without having to deal with any particular difficulties and great costs. If you can solder together, it’s easier to get yourself into troubles and get rid of them.

As a butt, we will win the receiver for the Tricolor TB GS-8300 N television station. Prote a lot of subscribers win the receiver itself, and not all of them work correctly.

The main problem of the largest number of receivers is the faults in the living system and the voltage change. In addition, a short circuit in the LNB coaxial cable often causes damage to the modulator. Only in the rest of the models began to vikoristovuvaty disgraceful zahist, which, when fading, attaches the supply of voltage to the converter, until the faucets stop falling asleep.

Also, there was a problem: the receiver does not turn on and does not give a sign of life, and the indicators of the front panel do not light up. They tried to switch the plug from the socket, turn on / off the toggle switch - it does not help.

Then we choose further. On the back, it is necessary to twist the plug from the socket and remove the top cover for additional twisting. We need to take a look at the electronic filling I will add. Here it is important to remember that we will break the guarantee seal in an hour when the cover is lifted.

Because the warranty term has not yet passed, rather do not lick yourself, otherwise you will not be able to repair your receiver after the warranty.

And if the guarantee has passed and you have no one to rely on, then go ahead - take the seal.

After tidying up the lid, you can make other payments with different components. The stinks are smashed between themselves with tires of darts. The photo shows the deakі pristroї z description. We need to know the fee for eating. There is a transformer installed on it and a pidwid for a lace cord, so it’s not easy to know. First, on which varto turn respect, tse zapobіzhnik, which, as a rule, is installed on the ear of the lanceug. Zapobіzhnik can be of different forms, for example, a glass capsule with a conductor, or a small plastic box, in the yak of the premises of the zapobіzhnik. For another person, it is necessary to remove the lid of the box (you can use tweezers or tweezers) to get to the very zapobіzhnik. Dali it is necessary to check the zapobіzhnik with a tester and a multimeter for opening. If you have burned out, if you are most likely to trap, then go to the radio equipment store, buy the same zapobіzhnik and just remember yoga. As if everything is fine from the foreigner, then we robbed the re-verification given in the Lanziug.

Another element that often breaks down is the transformer without a middle. Such an inconsistency is manifested by the additional mitigation of the voltage on the secondary winding. Replacement of the transformer is not dermal under force. If you are not convinced that you yourself can change yoga, then it’s better to bring your assistant to the repairman, and if you don’t think it’s foldable, then go for it.

There is one more inconvenience - tse vyhіd z fret elektrolitichnogo abo oxide capacitor, scho to stand at the entrance through the hanger. In order to detect this breakdown, it is necessary to know a little about the radio mechanics. A faulty capacitor sings of a yellowish color, so the very base of the bottom on the board can be seen as a small brown flame. In addition, you can change the rated capacity of the capacitor to determine its correctness.

The second place at the receiver transforms the changeable streak at the straight line.

Diodniy mist can also be angry. It doesn’t matter if it’s wrong, the oscillators of the conductor diode have one main function: to pass the strum in one bik, and in the next - not.

In this case, the breakdown was in the transistor of the primary winding of the transformer. Vіn maє a radiator for the introduction of heat, it's easy to know it. The error was revealed as follows: they measured the voltage on the transistor’s emitter, there was no yoga there, the primary winding was not eating, then, all the details were repaired. The transistor's variance is close to 30 rubles. To replace yoga, we need a soldering iron. Usuvaemo injustice, and - “Hurrah! Zapratsyuvalo!” - receiver znovu harazd. Significantly, the transistor does not break often, it is more important that the receiver gets out of tune through the zapobіzhnik.

Let's look at one more wide-ranging inconsistency - zlіt firmware. Tse vіdbuvaєtsya dosit often. I am familiar with the firmware є outside the hang of the receiver. Then we need to just reflash the primer.

The reason for the failure of the receiver may be non-yakіsny, non-professional installation. If the insulation of the cable is damaged, then the water from the outside can easily penetrate the inside of the cable and, like a hose, seep into the receiver, flooding the entire inner space. That's why it's necessary to follow the cable, because there's no way to break it or damage the insulation.

Tim, who doesn’t understand anything at the internal annex of the satellite receivers, but whoever cares about it, don’t fall into the house if I break the annex. The service center hasn't swayed anyone. There you can find out about your problem and fahіvtsі help you її virіshiti.

Receivers go out of tune for various reasons

The receivers go out of tune for various reasons - the voltage drop, the wear of the attachment itself through the intensive vikoristannya, and the visibility of the elements. Here you can fix the breakdowns through the Vlasniks, as if you yourself were solving problems, not looking for those special skills, for example, they incorrectly replaced the firmware on the satellite or cable receiver.

The block of life is, perhaps, the very part of the receiver that is breaking. The block of life can be broken through a non-standard mesh of life, through non-standard radio components (especially on cheap Chinese technology).

Drank and ford can lead to a primary attachment to breakage, creating an incorrect thermal regime.

I drank and ford at the receiver and can also bring the primary attachment to breakage

At the service center, repairs are being carried out and maintenance of the various satellite equipment. Moreover, repairs are carried out by facsimiles and on a professional installation. Practically, whether a faulty part can be replaced with a new one. The term for the repair of stale parts in the presence of parts at the service center. As if it were a detail every day, then її ask the post-employees to take an hour. But in the great serious centers, as a rule, the details are always in evidence.

Let's take a look at one more situation: the receiver is viishov out of tune after the voltage cut. After seeing the cap, it was revealed that the following details had burned out:

mesh capacity C5 - 47µFx400V

R8, R11, R13 - skin 3 Om each (tyrosmir 1206)

R9 - 47 Ohm (1206)

U1 - type of non-values

On the Internet, we found a side with a table about how to recognize and select analogs (for example, http://remont-aud.net/ic_power/), we wonder behind it that we don’t have anything. I will replace the part on the SG6848, in order to minimize the installation of the factory circuit.

We are dismantling faulty parts (the red name is circled in the photo):

R8, R11, R13 - 3 ohm (1206)

R3, R6 (one of them is possible) - 1 MOm (1206)

Video-look: repair of the Tricolor GS8300 receiver (no signal)

———————

On March 28, 2011, it is necessary for all subscribers of "" to receive the GS-8300, GS-8300M and GS-8300N via satellite to version 1.0.157.

Repair of the receiver Tricolor GS8300

Hello everyone. Today I will show you the solution, as a broader problem has emerged. One miraculous wound, zbirayuchis marveling at the TV set, embarrassing the black screen. Marveling at the receiver of the tricolor, remembering that the one was dead. 🙂

The GS8300N receiver did not respond to the live feed (the indicators were not saved). So, as a guarantee, I ended a long time ago, having sorted out the device. The picture was unreceivable, burning the receiver's live block. This receiver, like a TV from the day of purchase, was powered through a voltage stabilizer, but it didn’t blow.

The condenser for eating is dry and blown up, due to overheating, the radio elements burned out.

In order not to spread plagiarism from the text of the video, it helped me repair the receiver's live block. The new one describes the repair process in detail. Before that, the scheme of the troch was reworked and pratsyuє vіdmіnno.

I'll show you how to repair it, and then you write it yourself, there's no other way.

• Microcircuit - 60 rubles
• Diode - 2 rubles.

If your arms are straight, then that’s out of the way!

After re-verification of the diodes, having revealed one penetration.

The axis is the original diagram of the receiver's living block.

And there's no video! 🙂

Just in case, get radium for thanks. Yakshcho did not understand the obov'yazkovo in the comments. Everything worked out for me the first time and the scheme was reworked to work miraculously.

Repair of the receiver tricolor GS8300. Reworking the living block. The typical error of the tricolor receiver gs8300 is more frequent and sounds at the exit from the fret of the live block. Repair of this block of life for an hour to complete the folding through those that do not have the original microcircuit of the shim controller. Alternatively, you can convert to another available microcircuit 5L0380 by changing the installation of the living block. Too many coristuvachiv in case of a breakdown of a computer, a laptop or a rare-crystal TV set, they immediately turn to fahivtsiv, so they can repair everything. From one side - not right, but from the other side - the ability to make the simplest repair, such, for example, like replacing a BIOS battery, would not be minimal. Therefore, for the coristuvachiv, yaki not to be afraid to take a soldering iron and a twist, a special channel was created https://www.youtube.com/user/texremont1. In case of faulty failures in a robotic laptop or a tablet, it is not easy to repair and analyze the outbuildings. On the TexRemont channel, you can watch hundreds of videos dedicated to this food. They have selected video instructions, in which professionals report on the features of working with different models of laptops, video cards and motherboards of different types. With this description of the main problems, those ways are the ones that may be blamed on the process of exploitation. A detailed description of the selection of laptops and tablets of various brands of various brands can also be admired without any particular problems. Not a skin person can boast about it. What should be done with such a simple add-on, like a soldering iron, a soldering station. The features of today's infrared stations are described on the TexRemont channel, and if ever you can look at the report video lessons of robots, which are related to such an important feature as chip reballing, which is the basis of modern electronics. Repair of computers and their components to complete the folding and laborious process, which requires knowledge and experience. On the TexRemont channel, the report describes the main problems in such situations, if the computer has failures on the hardware level. On the channel, the features of the modernization of computers, the connection of various outbuildings and gadgets are reportedly described. Hundreds of videos will help electronics-learner to choose the right equipment for repairing computer and digital equipment and learn how to work with it. A detailed description of the current technologies of soldering and installation of equipment should be taught to anyone who wants to independently repair laptops and computers.

Ferex R&D FP09T001 Rev.2 receivers were selected for the circuit of a pulsed reversible voltage changer, shown in fig. 12. Inlet merezhna changeable voltage 190 ... 240 V with a frequency of 50 or 60 Hz through the fuse F1, the overshoot filter C1LF1, which overrides the penetration of the overshoot from the dzherel into the merezh, the jet-streaming resistor RT1 and D4.

GS-8300 satellite receiver wiring diagram

The last resistor RT1 connects the starting stream through the diode place D1-D4 for the hour of charging the capacitor C5. Varistor RV1 protects the circuit from overvoltage. When the voltage is changed, the permissible value of the opir of the varistor changes, the strum that flows through it increases and the fuse F1 burns out.

The constant voltage is forced to pass through the control unit of the primary winding of the transformer T1. It is commuted by a hard-wired transistor Q1, which is connected by a Shi-controller U5. The energy accumulated in the transformer is transferred to the secondary winding and rectified by diodes D5. D7-D9.

To start the dzherel zhivlennya, when the wire is switched on, the voltage is rectified, which goes through the stream-coupling resistors R4, R5 to the circuit of the microcircuit 5 U5. After the start, there is a voltage on the secondary windings of the transformer T1 and the U5 microcircuit is alive with a voltage, rectified by the D5 diode, through the resistor R19, which surrounds the stream.

Stabilization of external voltages of the dzherel zhivlennya is provided by U2 elements (optocoupler, which galvanically separates the primary and secondary lances of the dzherel) and U3 (voltage stabilizer). The nominal value of the output voltage is set by the dilnik R25R26. When the processes are increased, the transistor in the optocoupler U2 turns on, and the SHI controller U5 changes the pulse trivality, which turns on the transistor Q1.

As a result, the energy that is transferred from the second lansy changes and, consequently, the external voltages change. A linear voltage stabilizer of +5 V was selected on the field-effect transistor Q2 and microcircuit U4. The old look of the living life is shown in fig. thirteen.
