Television is an essential entertainment facility for families, especially with the development of science and technology, television has become colorful, from black and white to color to LCD, and television has become a "member" of family life. There will be some faults when the TV set is used for a long time. How to deal with these failures?

Common faults of TV set and their treatment 1

Fault and reason: the whole TV set is out of power, which is mainly caused by internal power supply and external power supply. Generally, the failure rate of off-board power supply will be higher.

Solution: The fault caused by the power supply part can generally be solved by replacing the parts; If the drive board fails, it is necessary to check whether the power supply is normal. The failure of the driving board caused two groups of power supplies to have no output voltage. If there is something wrong with the voltage, it must be the fault of the driving board.

Common faults and treatment of TV set II

Fault and reason: the display screen is black, without backlight, and the green light of the power light is always on.

Solution: There are images on the display screen, mostly due to the failure of the power supply circuit of the high-voltage board. Focus on checking whether the power supply and switching voltage of 12V are normal.

Common faults and treatment of TV set 3

Fault and cause: there is sound but no image. First of all, there may be something wrong with the tuner, and the color system may not be adjusted correctly.

Solution: There is no image input after the tuner is damaged. Check whether the related parameters of the tuner are normal before replacement. Then adjust the color system of the TV, which is usually rare. When you turn off the TV, you can see the light of the TV with a little discharge sound, so you can conclude that the TV picture tube is normal.
