DIY TV repair Mystery

Mystery TVs belong to the category of inexpensive modern household appliances. However, even they can sometimes fail. But not in all cases, when the device has stopped turning on or the sound has disappeared on it, it is necessary to contact a specialist immediately. In this article, we'll look at how you can fix these issues yourself.

The most common problem faced by the owners of TVs of this brand is that the device simply does not turn on, most often it does not start from the remote control. Although in some situations, no manipulation helps. In this case, certain indicators on the TV itself are lit. Let's consider how you can solve the problem in each specific case.

If the light is not constantly on, but blinks, then it is probably There has been a breakdown in the device software. In this case, you just need to reboot it. If the problem still persists, then a complete reinstallation of the software and possibly the purchase of a new power supply will be required.

If the red indicator is on constantly, and the TV does not turn on from the remote control, then you need to find on the TV panel itself (usually on the right side of the side) the on / off button and try to turn on the TV with it. For some models, the device starts up by pressing the "SOURCE" button. It is also necessary to make sure that the correct batteries are inserted in the remote control.

If there is no such button or the device does not turn on, disconnect it from the power supply and leave it alone for a few minutes. Then reconnect to the network and try to turn it on without using the remote control.

If it is constantly highlighted, this means that a malfunction in the matrix may have occurred or it has failed. In order to check this, it is necessary to disconnect the device from the mains and remove its back cover. Take a close look at all boards and the main control matrix. If it has dark unnatural stripes, then it needs to be replaced.

If the blue indication flashes constantly, and even at different intervals, it is necessary to carefully study the instructions for the device itself... Such a problem indicates some kind of internal error on the TV, which makes itself felt in the form of such a signal. The reason for its occurrence and the remedies should be written in the user manual.

If the indication changes its color from blue to red, it says about several problems in the operation of the device that arose at the same time... In this case, you should not try to repair the TV with your own hands - professional tools may be needed here.

In some cases, if the device itself overheats or problems with its kinescope, the screen may not light up, and the blue indicator will also light up constantly. This means that there is a problem with the broadcast of the image. In this case, when you try to switch channels, the sound will appear, but the image will not. In this case, only a professional master will be able to determine the exact cause of the breakdown.

And one more thing: if the TV screen was connected to the computer as a monitor, but the connection channel itself was selected incorrectly, then an indicator of any color may light up. Therefore, it is necessary to check both the correctness of synchronization of devices with each other, and the correctness of the selected connection channel.

Sound skips in some situations. But even in this case, the repair of the Mystery TV can be done by hand.

• If sound is missing only on analogue channels, you must make sure that all the settings of the device itself are correctly set. You also need to check if the region of residence is one of those where channels with this type of broadcasting are already disconnected. In this situation, only the installation of a satellite receiver can help save the TV.
• If the sound has disappeared altogether, but the image is still there, you must first check the level of the set volume on the device itself. And if necessary, you should add it.
• If the TV turns on but there is no sound or picture, then there are problems in the microcircuits. Here it is also necessary to disconnect the device from the mains, remove its back cover and carefully inspect all boards and circuits for spots, stripes or damage. If everything is in order, then there was an error either when connecting the device or in its internal software. You need to restart your TV and reset all settings to factory defaults.

And one more thing: even if you yourself managed to establish the exact cause of the malfunction, but there is even the slightest doubt that the repair work can be performed safely and correctly on your own, you should contact the repair shop.

But sometimes in the work of the TV of this brand other malfunctions may occur, which you can also solve yourself.

• When viewing, the image partially disappears or disappeared altogether. This means that the periscope has been interrupted. After diagnostics, it will become clear whether a repair or complete replacement of the device is required. Diagnostics should only be carried out in a repair shop.
• The TV does not turn on at all and there is no indication - problems with the power supply. It needs to be replaced.
• TV turns off spontaneously... Protection (against overheating and spontaneous combustion) can be triggered here, or the factory settings are set to turn off the device during continuous operation for more than 5 hours.

Before proceeding with the diagnostics of the boards and microcircuits of the TV, it is necessary to make its external examination: make sure that the case is intact, that there is no burning smell, that all wires are connected correctly and that the backlight is working properly.
