Wide white stripe down the middle of my TV

@truditennis we would need to know what model your Toshiba TV is. Also, it will help if we can see what your screen shows you. Post some pictures of it with your QUESTION. 기존 질문에 이미지 추가하기 If it has a solid white vertical band, then the cause is most often the panel. It could be an issue with the LED driver board connections to the panel. You will have to check on those. This is an example of what you would have to check on for corrosion etc.

How do you clean/have cleaned your TV screen in the past?
