First, Wedges Not long ago, a 42-inch Haier LCD TV of the daughter's house was watching, and during the process of changing channels, it suddenly found that the screen color was wrong. The face has a negative image. I asked a home appliance repairer to come to the door. The master looked at it and said that the screen was broken. No way to repair!
So she is ready to sell the waste. I heard that. With the hobby of electronic technology and some experience, I feel that when the scrap is sold, it can only sell for tens of dollars, which is not worthwhile. It is better to show me that there is no way, even if the repair is not good, the value of the removed boards and components is far more than tens of yuan. So she moved the bad TV set a while ago.
