I've got a rca hdlp50w151yx3 about 1.5 yrs old having a problem.Anyone with a similar prob or professional input is appreciated.When turning on it starts a buzzing sound that cycles on and off every few seconds 3 or 4 times and then starts flashing the power button.The lamp never lights,cooling fans or color wheel don't turn.I don't think it's the lamp as it's done this a couple times and after several tries it starts normally.I took the lower rear panel off and the buzzing is coming from a small cylindrical component on what I believe is called the lamp ballast board just fwd of the lamp housing,it glows bright as a led when it's buzzing,not sure what it is,it doesn't look like a cap.I'm not sure if it's the problem or a symptom of the problem.I think it's this ballast board thats the problem.The installed lamp is a 260962,the ballast board does not have a number on it that I can find.Does anyone have a good source for ordering lamps and ballast boards from.
