Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

TV would turn off by it self and make a cracking noise. Looked in the back and saw an arc from the lower left.

Tv was turning on and off on its own. I tried to unplug it for four hours and see if the safety mechanism would reset. When i turned it back on i heard a noise and saw an arc coming from the back left. I took off the cover and saw a burn mark on the bottom left card.

That could be a number of things that would make that noise, Have you removed the front panel screen in front on bottom and try turn TV on Look for Spark? Bad anode button on one of the tubes can cause that, bad flyback transfomer.Have you removed back and look to see if arc is coming from the FBT Mounted on Deflection board. First board on the left is the deflection board.

Tv turns it self off after only 2-3 seconds and makes crack noise


Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.
