I have sound but no picture and the lamp light is flashing. I hit the reset button and had the same problem, I then unplugged the TV for an hour and still nothing. so I have been pricing lamps. I am a do it your self repair person and have electronic background. I just want to know before I order the lamp and break down the tv if it is a difficult task and while I have it torn apart any thing elese I should do and what to use to clean it with.
