Question about Hitachi 42V715 Rear Projection Television
My lamp went out and then there was a loud buzzing sound from the back. I took off the back panel and on the right is a small circuit board. There is a small (maybe 1/4" in diam. and height) white cylinder that buzzes really loud and glows like a light bulb. could this be just because the lamp went out? I dont want to spend $150 for a new lamp and still have a broken TV.
That white cylinder is a capacitor and is very dangerous, you need to discharge it and replace it. Does the top seem to be bulging on it? If so, it is bad for sure and it is cheap for a new one. If it continues to buzz after replacing it, then your board has a problem. Replace capacitor before replacing lamp. The lamp still may be good
