A plasma TV can also experience a number of unpleasant problems.

The design of Lg plasma TVs is fundamentally different from liquid crystal devices. The image in an Lg plasma TV is formed by applying current to gas-filled cells. Under the influence of current, the gas turns into plasma, and the cells covered with a multi-colored phosphor begin to glow. The shades of the glow are determined by the color of the coating.

The plasma may fail due to burnout of the phosphor coating. To avoid burnout, do not place your LG plasma TV in direct sunlight and do not force the device to broadcast the same static picture for a long time.

If a problem occurs in the plasma TV program, it must be resolved by flashing the device. To fix this problem and successfully repair the Lg, no experience in soldering is required, and the likelihood of permanently breaking something is low.

This technology has long been present in people’s daily lives, so plasma TV repairs are carried out by many companies and private specialists.

If the plasma does not turn on, locate the faulty scan strip. A bar is a number of scan controllers responsible for a row or column of the screen. However, it is better to entrust repairs in cases where the plasma does not turn on to specialists from the service center.

There is sound, but no picture

Most faults are best resolved at a service center. Repairing LCD TVs is expensive, and in the process you can accidentally damage many elements that still have their functionality.

Poor contact between the cables and the matrix connector;

Reducing brightness through hardware settings;

The backlight circuit has broken;

The LED driver responsible for powering the matrix has failed;

The software control failed;

The motherboard is damaged.

Screen flickering

The screen flickers. The flickering image is dissected from time to time in wide stripes. Tapping the side of the device may provide short-term relief. The cause of the problem lies in poor contact between the connector on the matrix and the cable. To deal with the problem, disassemble the device and securely fasten the cable in the desired socket.
