Prefix World Vision T34

Set-top boxes of digital television entered our lives not so long ago, but in addition to positive aspects, they cause a lot of criticism from the side of quality. It is still too early to talk about some statistics and how much they work out for failure, but already now there are quite a few cases of failure in the operation of these TV set-top boxes.

I will list some of the most common malfunctions in which the prefix refuses to work:

the red indicator is on;
red indicator flashes;
the console reboots and does not turn on;
writes "ON" and does not turn on (the green light is on);
the tuner does not turn on after the firmware;
does not turn on from a distance.

The reasons why the tuner does not turn on can be divided into several groups:

Electrical circuit malfunction;
Firmware failure;
Remote control malfunction.

In case of any breakdown in the circuit, it can manifest itself in different ways, but the worst thing is that with the same manifestations, the reasons can be completely different. For example, when the tuner is connected to the network, the red light (network indicator) is on, but it does not go further than this, that is, the set-top box does not respond to the remote control and control buttons. This case may apply to any of the groups listed above.

The purpose of the article is not to analyze the device of the set-top box and how to repair it, but to give an idea of how at the first stage to try to independently diagnose and draw any conclusion about the malfunction. If there are no repair skills, you need to contact the repair service, since repairs require not only knowledge, but also special equipment.

CIRCUIT FAILURE

It all depends on the quality of the circuit elements, so well-known brands producing DVB T2 tuners that use a higher quality element base are more preferable.

The easiest way to diagnose a breakdown is when the indicator (light on the panel) does not light up. This clearly indicates a malfunction of the power supply.

If the light is blinking, this may indicate a malfunction of the PSU, and the chassis (this is the main board with the tuner and processor) of the set-top box, as well as a firmware failure.

In the case when the device spontaneously, repeatedly reboots and does not turn on, all the same elements of the set-top box can be to blame. You can read about such repairs. If the display reads “ON” and the indicator is green, and the set-top box does not turn on, then this may also indicate a malfunction of the circuit.

FIRMWARE

As noted above, in some cases it is rather difficult to separate what exactly is the cause of the malfunction of the firmware or the electronic part of the circuit without additional measurements. But if the tuner does not turn on after the firmware, then the conclusion is unambiguous, it is she who is faulty.

Here you need to warn that you need to be careful when updating, follow the instructions and install exactly the firmware that is required for your device.

With such a malfunction, you need to contact the service, although not every center undertakes such repairs.

REMOTE CONTROLLER

On many cheap models of set-top boxes, there are no control buttons on the front panel, and this is a significant minus, since if the remote control malfunctions, you lose the ability to control the tuner at all. This has already been written on the site in an article about choosing a prefix.

Therefore, if the remote control from the digital set-top box does not work, only buying a new one or a master will help to identify it. Unfortunately remotes for tuners are still rare and quite expensive.

It happens that the tuner does not turn on from a long distance, both the tuner and the remote control itself (which is rare) can be guilty here. You can try replacing the batteries, but if it doesn't help, buy a new one. If in this case there is a negative result, then the prefix is \u200b\u200bto blame.

Once again, without special skills, it is difficult to solder parts on your own, which can cause great harm to the board.

Updating the software (firmware) of your equipment is performed only in cases where there are any problems, or the update will add useful functions to the device. It is not recommended to flash devices without the need, because. during the firmware update process, there is a possibility of equipment failure. If you are not sure that you can handle the firmware update yourself, we recommend that you contact the appropriate service center with qualified specialists.
