Electronics Repair: Top 5 Typical TV Failures

TV outage is always an unpleasant incident. Firstly, you can skip the latest episode of your favorite series, and secondly, there are unnecessary worries: you need to look for a repair service for the equipment or take up the repair yourself. Both require time and expense, and a good result is not guaranteed - perhaps the TV itself will have to be replaced. But many failures can be diagnosed at the first sign - consider the typical problems and the "symptoms" of their manifestation.

1. In the first place in popularity are “external” failures that are easy to fix on their own: the remote control does not respond - the batteries are corny or the contacts of the buttons are dirty; the TV is very hot - the radiators of the cooling system may have become dusty; The antenna has broken - it is worth checking the cable connection. If you have problems with the equipment, the first thing to do is to eliminate such problems.
2. The device does not turn on or periodically turns off spontaneously. The problem is in the power supply: it could be damaged or simply burn out during a power surge. Despite the run-up of the permissible voltage from 90 to 240 V, this is one of the main reasons for the failure of modern TVs. A complete diagnosis of the device is needed to accurately determine the cause and degree of damage.
3. No sound. A few assumptions: the settings of the TV itself are knocked down; built-in speakers are faulty - it is worth checking the elements, as well as their contacts; motherboard is damaged - microcircuits could be damaged due to water or voltage drops. It is not recommended to unwind the structure yourself: it is easy to damage parts.
4. The technique “freezes” during the settings of functions, channels are not saved, USB connectors do not work. Good reasons to worry - motherboard crashes. This is the “brain” of the device, a high-tech processor with a high density of microcircuits, therefore, in this case, electronics repair is required in the factory - the manufacturer will completely replace the element. It will be lucky if the problem is fixed under the guarantee - buying a new board will otherwise be expensive.
5. A whole block of problems with the image signals damage to the matrix: noise on the screen, the appearance of vertical and horizontal stripes, a blinking display, the disappearance of one of the colors, the absence of a picture. A common cause is mechanical damage due to shock or liquid, as well as the failure of the matrix backlight. The breakdown is serious - and you can’t deal with it yourself: in 90% of cases, failed elements cannot be repaired, and replacement will cost the purchase price of a new TV.
