Question about RCA HD44LPW165 44" Rear Projection HDTV
My tv just stopped showing a picture. There is sound, but the green power light blinks. After a couple days, i turned it on and it worked again. Now it doesn't AGAIN. I checked the lamp, and it is fine. I did notice some minor "squealing" cominf from or near the lamp housing. I live in a 100 year old house with poor wiring. Could it not be drawing enough electricity?
The sqealing noise is going to be one of the cooling fans or the color wheel. The color wheel is famous for making noise. Some are louder than others. The most likely culprit is going to be your ballast. You can find them on Ebay for under 100 dollars. You can also find a spare bulb for around 85 dollars. I made it a habit to keep one on hand just in case it went out right in the middle of something.

The squealing is the power supply off frequency its trying to produce b+ voltage there must be something loading down the b+
