Hi, I have an older Sharp LCD, model # LC-C5262U. It has green dots on the screen, sometimes its just along the top, and then it will spread to the entire screen. It just started, the TV wasn't disturbed in any way, it sits out of the way so it wasn't hit or jarred. I also tried replacing the T-con board with 2 different boards, and the problem persists. It is also independent of any input, the green dots are on the screen all the time on all the inputs and without an a/v cable connected to the TV. If anyone has any suggestions on what to try next, I would really appreciate it.
