The screen continuously flickers, changes color (whole picture goes green, or purple), the picture changes sizes for a second or two, and eventually the tv will turn itself off. If this happens, I have to unplug and replug the tv to make it work again, but sometimes the screen still remains black while the audio is fine. Someone came to repair this just today, and the problem has already resurfaced within an hour. Any explanations as to what could be causing this?
