What should I do if the Haier TV always has a black screen?

Please ask the relevant maintenance personnel to come to deal with it.

The black screen of the TV is a malfunction phenomenon of the TV, and it is also the most common, which is manifested as no image. There are generally two main situations of TV black screen; One is that there is no image, there is sound, and the TV screen is not lit; The other is that there is no image, no sound, and the TV screen is bright. These two conditions are the most common black screen phenomenon.

There may be several reasons for the black screen of your TV:

First, it may be caused by the abnormal power circuit, which is manifested as the button does not respond when pressing the panel, and the indicator light does not light up. One possibility is that there is a problem with the input stage of the power circuit; First check whether the 12V voltage is normal, then check the 5V voltage, if there is no 5V voltage or the 5V voltage becomes very low, there is a problem with the input stage of the power supply circuit. This kind of failure is very common, generally because the fuse is burned or the voltage regulator chip fails, and the relevant parts can be replaced.

Second, if the circuit source is normal, then there may be a problem with the circuit driving the backlight. If there is a problem with the circuit driving the backlight, connect the display to the host to check it on and close to the screen to observe carefully, the common faults of the high-voltage board are the fuse of the high-voltage board itself burned out and there is no 12V** and switch chip failure, etc., replace the relevant components.

Third, there is no problem with the above two aspects, then it may be that the circuit of the switch part of the control high-voltage board on the AD board is faulty. Fourth, there is also the backlight of the screen is broken or other special circumstances.
