Why does the tricolor receiver lose sound. Connecting via SCART

03.05.2019 Operating Systems

According to the manufacturer, you need to periodically update software on satellite receivers, which provides correct functioning all devices.

Reception degradation and control problems are hard to avoid. However, the planned firmware of the device does not guarantee correct work. Big number users complains why there is no sound on some Tricolor channels.

Lost sound on all channels

In this case, you need to do the following:

Try out the sound (Mute key), the volume on the remotes.
Check the correctness and continuity of the cable connection of the set-top box and television receiver- at correct connection unplug the device from the mains and plug it back in. If there is no sound, adjust the device to the manufacturer's specifications (Menu - Settings / Settings - Manufacturer's settings).
If there is still a problem with the sound, you should contact the customer service center or the company's dealer to check the device.

Some channels with sound only

In this situation, you need to take the following actions:

Connecting via SCART

check the detachable contacts at the connection points;
check the correctness of the choice of sound track. Convert it to another format by pressing the green F2 key on the remote control and selecting the sound mode ("Russian AC3" or "Russian");
if the sound track is selected correctly, disconnect the device from the mains and turn it on. If there is no sound, reset the settings;
in case of absence desired result contact the Customer Service Center or the manufacturer's representative;

RCA connection (bells/tulips)

check the connection of three cables to the television receiver. With two inputs in the TV receiver, you need to enable the Mono mode in the device (Menu - Settings - AV output settings - Audio output);
check the correctness of the choice of sound track. Convert it to a different format, as mentioned above;
when the sound track is selected correctly, unplug and plug the device from the mains. If there is no sound, reset the settings;
If the sound problem persists, contact the Customer Service Center or your dealer.

Connecting through Another

Check if the audio track is set correctly. Convert it to another format;
with the correct sound track selected, turn off and turn on the receiver in the mains. If there is no sound, reset the settings;
if after this tricolor sound is lost on all channels, contact the Service Center or the dealer.

What should I do if the sound is lost after the update?

Based on practice, the sound rarely disappears after the receiver is flashed. In most cases, this happens for the following reasons:

due to accidental pressing of the Mute key;
due to a violation of the physical connection of the device and the television receiver. If there are no problems with the remote control and wires, it is recommended to reboot the device. If there is no sound on all channels in the tricolor and after that, you can try resetting the settings.

What to do if there is no image, but only sound?

ripple

Connection via 3RCA ("tulips", "bells").
It is recommended to replace the cable with an analog one, use a different connection, for example, Scart, HDMI, RF (determined by the availability of the connection method on the device). You can contact the company's customer support center and check the device.
Connection via SCART.
Disconnect the cable from the device and the TV receiver and reconnect. If there is no sound, connect in another way. Or go to the Service Center.
Connection via high frequency cable.
Set up all available TV standards one by one in the system settings of the device (AV output settings) while monitoring the problem. If there is no sound, it is advised to use a different connection method. You can contact the Support Center and diagnose the equipment.
Connecting via HDMI.
Need to replace HDMI cable. When this does not help, it is better to use a different connection. Or contact the company's customer support center to check the equipment.

Conclusion

In some cases, when updating the hardware software, you may experience various problems and customers need to set up the device and replace the cables. In most cases, this is done on its own.

Following our recommendations, even inexperienced user be able to deal with the problems that arise. It is necessary to take into account the unacceptability of interruption running processes and if necessary, call hotline. Manufacturers know best how to fix problems with their equipment.

Each satellite TV user periodically faces the need to download new software from the satellite. It is assumed that this operation will improve the performance of the receiver and the quality of broadcasting TV channels. But it also happens the other way around - after the update, Tricolor does not work, TV channels disappear, number errors occur, etc. Let's try to deal with the most common problems and consider options for resolving them.

Most Common Problems

Most often, satellite TV users complain that after downloading new software, the following problems occur:

does not show multiple channels;
there is no broadcasting on all channels;
sound does not work
the receiver does not see the smart card.

It is unlikely that it will be possible to accurately name the causes of these failures without additional testing of the equipment. But there is one option that is recommended to work out first.

Incorrect software download

The main rule for flashing a set-top box, whether from a satellite or from another source, is not to turn off the equipment until the new software is installed. Otherwise, a Tricolor TV update error occurs, which can lead to any of the above failures.

Therefore, if one of the following situations occurs during the download of new software:

voltage drop in the power supply network;
emergency power outage;
turning off the receiver by user error;

repeat the download process. Before doing this, it is recommended to restart the prefix by power supply. This usually resolves most issues.

Instructions for restoring broadcasting

It happens that, even despite the correct download of the software, it does not show Tricolor after the update.

Important! If the prefix gives some kind of error with a number, you should first take steps to eliminate this particular error.

Independent channel search

Tricolor devices have a built-in automatic channel search function. If, as a result of downloading new software, the user lost broadcasting at all frequencies, it is worth using it in the first place. For this:

go to the equipment menu;
go to the "Applications" or "Settings" section;
select the "Settings Wizard" item;
start auto-search for channels;
wait for the list of found frequencies to appear on the screen;
save the output list.

Important! This method can help if after the update Tricolor TV does not show channels at all frequencies or only some of them do not work.

Resetting the receiver

If the above method did not help, you can try resetting the set-top box to the factory level. By the way, this method helps a lot with most number errors, and if the receiver refuses to read the smart card.

To roll back the settings you will need:

open the receiver menu;
go to the "Applications / Settings" section;
find the item "Factory settings / settings";
to confirm the operation, enter the pin code.

After that, the receiver will automatically reset the parameters set on it. The user only needs to wait for the device to reboot, and then set necessary settings again.

Important! If channels are not shown on Tricolor after the update, and even rolling back the settings did not help get rid of this trouble, we recommend contacting the dealer from whom the receiver was purchased, or the company's service center.

Other possible problems

On many independent forums, you can find user complaints about the incorrect behavior of the equipment after flashing it from the satellite. Most often, subscribers write about the following problems:

after the Tricolor update, the sound disappeared;
The receiver cannot communicate with the smart card.

Let's consider these situations in more detail.

No sound

As practice shows, the loss of sound is very rarely associated with the download of new software. The user should check:

Is the Mute button pressed on the remote control?
is it broken physical connection set-top box and TV receiver.

If everything is normal, it is worth restarting the receiver by power - this usually helps to restore the sound.

No connection to smart card

If Tricolor does not see the smart card after the update, the reason, again, is not always the new software. Perhaps the card has simply expired, and fresh software simply refuses to work with it. Also possible reasons are:

wrong software version.

To fix the problem (after checking the expiration date of the card), re-flashing the receiver will help. Before making it, we recommend checking current version working software on the operator's website.

How does it happen that after latest update GS 8306 receiver firmware up to version 1.9.160 before that, a normally working receiver becomes somehow uncontrollable. If, of course, at all becomes. Indeed, many receivers do not withstand the process of flashing to version 1.9.160 and stop turning on. The same receivers, which nevertheless completed the firmware procedure, are buggy on the new firmware in every way. They can freeze when viewing, freeze when switching channels, display a “no signal” message, and produce out of sync audio and video streams. And in general, to make a number of other things dear to the heart. And having received such a receiver after flashing, you can decide that it simply broke. But common sense tells us that it just worked fine on the old firmware, which means that it's not about the hardware component of the GS 8306 receiver.

What can happen to the GS 8306 receiver after updating to firmware ver. 1.9.160

1. The tricolor tv receiver gs 8306 does not turn on after the update

In such a situation, it can be assumed that the firmware was not completed to the end. It means that old firmware already erased, and the new one was never loaded into the receiver's memory. In this situation, the receiver turns, as they say in slang, "into a brick." Similar problem solved either by replacing motherboard receiver (which is quite expensive and difficult to find a replacement board), or a separate firmware of the receiver's flash memory chip with a new normal firmware. For execution separate firmware it is necessary to unsolder the flash memory chip of the GS 8306 receiver, then, using the programmer, “fill in” a new one into the flash required firmware and finally re-solder the flash chip to the receiver board. In the presence of necessary equipment and the experience of handling it, the whole procedure takes 50-60 minutes.

2. receiver tricolor tv gs 8306 does not show via hdmi

In the new firmware 1.9.160, the active video output control mode has been updated. If earlier the active video output on the receiver was selected using the “input. sing" on the remote control, pressing which alternately activated either 3RCA (tulip), or HDMI video output, now the receiver has learned to independently determine which video output to make active. But in order for the mechanism automatic detection active video output worked correctly, it is recommended to connect the 8306 receiver to the TV at a time with only one cord. If both 3RCA and HDMI cables are connected at once, then the receiver may not understand which video output to activate.

Another important aspect is the change in the mode of operation. LED indication on the front panel of the receiver. Now the uniform glow of the upper LED means that the receiver is in standby mode and to start viewing it still needs to be turned on using the remote control (on firmware prior to 1.9.160, the glow of the upper LED meant that the receiver is on and works through the 3RCA output)

3. receiver tricolor tv gs 8306 gives a pink picture

There are videos on YouTube in which you can see how great the picture from gs 8306 looks in pink. This bug is related to the update to 1.9.160. The problem is temporarily fixed by resetting the receiver to factory settings. repeated search channels. But then it reappears. The problem is completely eliminated by flashing the receiver to a different software version.

4. receiver tricolor tv gs 8306 after flashing constantly freezes

The reason for this, presumably, is the same firmware. Which, presumably, has a greater load on the processor than the previous version. The elimination of such a difficulty again leads to the need to replace the firmware.

5. The tricolor tv receiver gs 8306 often loses the signal after the firmware and writes no signal.

Also, the problem under consideration can be expressed in the fact that when searching for channels, a random number of channels is found, how lucky - the receiver can find 86 channels, after a minute 140, and after another minute 57. Possible Solution in such a situation, change the local oscillator frequency by 1 Mg up to a value of 10751 MHz (both the upper and lower frequencies of the local oscillator). On several receivers, we performed such an increase in frequency, after which the receiver began to work more stably, and the signal stopped losing.

What to do if the GS 8306 does not work, and there is not the slightest desire to repair or change it to a new one?

In the event that only 20 basic federal channels, it will be possible to switch to receiving digital terrestrial television. Digital terrestrial television broadcast reception is available in in large numbers settlements Russian Federation. As of December 1, 2016, digital terrestrial television broadcast in open mode and its viewing is carried out without subscription fee. But it's important to understand that satellite antenna not suitable for digital reception broadcast signal, which means that for reliable signal reception, you will have to install the usual broadcast antenna(internal or external), as well as purchase a digital DVB-T2 receiver (this is the case if there is no built-in one on the TV itself)

GS 8306 - how to return previous version Software after update to 1 9 160

It is possible to roll back the software of the 8306 receiver from version 1.9.160 to the previous version only with the help of a programmer - the flash memory chip containing the firmware is soldered, placed in the programmer, flashed with the selected firmware and soldered back to the receiver board. Roll back to previous versions with USB drive and the firmware will not be released on it - the new software does not allow updating to previous versions.

These are the thoughts on firmware 1.9.160 for the GS 8306 receiver as of December 1, 2016 from the date of its birth - September 27, 2016.

What are the prospects for the GS 8306 receiver? To the landfill? For a replacement?

In the event that the developer releases a new corrected firmware for the GS 8306 receiver, the prospects for this receiver are no worse than the prospects for other HD-class receivers for tricolor TV. On the need for release new firmware for GS 8306, the specialists of our SC have already informed the technical support of the tricolor TV operator by tel. 8-800-500-0123. Other tricolor TV users can do this as well. If new software for the receiver does not appear, then its operation may cause some difficulties.

1. No sound on all channels

You need to check if the mute button on the receiver and TV is pressed. Try turning up the volume on both remotes

Check the correctness and integrity of the connection of the cable connecting the receiver and the TV.
If the cable is connected correctly, turn off the receiver from the power supply and turn it on again. If the sound does not appear, it is necessary to restore the receiver settings to the factory settings (“Menu” - “Settings” / “Settings” - “Factory settings”).
If all else fails, then you need to contact Service center or to an authorized Tricolor TV dealer for diagnostics of receiving equipment.

2. No sound on some channels / intermittent loss of sound

Connection via SCART

Check the tightness of the contacts of the connectors at the connection points.

If all else fails, then you need to contact the Service Center or an authorized Tricolor TV dealer to diagnose the receiving equipment.
