Hello, I have a Viewsonic VA902B Monitor with the following problem, when it is cold it turns on the LED in green, it turns on the screen a tenth of a second and the lamps go out (it still has a video signal), I turn it off and on again, repeat it trouble. Until, at the time # 10 or more, they turn on the lamps and run smoothly. Even if you turn it off and on, while the equipment is hot. This team was changed several capacitors who were unhappy, a few years ago and it worked so far without problems. I checked those soldsdursoy they look right. Could the lamps be worn out? Does anyone know the size and specifications of the lamps? As to get one and try it without taking them out. Thanks since now. Fede
