What is the reason why TV lacks green?

General reasons and solutions for the lack of green in TV sets;

1, most of which are pins of video amplifier tubes or video amplifier integrated circuits on the tail plate of TV picture tubes.

2. There is a tricolor amplifier circuit on the tail board of the color TV. Maybe the green amplifier circuit is out of order. Therefore, the color is lacking, and it is recommended to find a professional to repair it.

3. Maybe the screen is magnetized. Turn off the TV (don't use the remote control) and then turn it on. Ordinary TV sets have automatic degaussing function.

4. If it is for other reasons, it is better to find a professional maintenance master to carry out maintenance, mainly to check the video amplifier board, picture tube, color decoding circuit, filament power supply of electron gun and other issues, so as to solve the problem that the TV set lacks green.
