Skyworth 50x6 LCD TV is turned on normally, and then it is preparing for the black screen of the home page. Why?

1. The voltage of the home power line fluctuates abnormally. 2. The fuse of the high-voltage board is blown. 3. Virtual welding or solder joint separation occurs between the high voltage inverter and the triode. 4. The external power supply and internal circuit of the TV set are out of order.

Suggested treatment:

1. When a black screen is found after startup, check whether there is a spark in the position of the power cord. If there is a spark, it is considered that the voltage is insufficient. Not only should you replace a brand-new power socket that is more suitable for him, but you should also add powder regularly to ensure that the voltage of the TV is kept in a normal state, so as not to damage the TV and let you use it normally.

2. The fuse of the high-voltage board is damaged, and there will be peculiar smell. You can smell it, too If it smells burnt, you need to find a professional to replace the fuse. It's not particularly difficult and the cost is very cheap. Just make a phone call and let the professionals come to the door.

3. For the phenomenon of loose or virtual welding at the welding point, you can find a professional to reinforce it. I believe their professional tools can solve this problem quickly, and can also detect inverter and circuit problems for you. If they have problems, they can also repair them in time.
