Question about RCA HD50LPW175 50" HDTV

1 Answer

RCA HD50LPW175 After the TV is on for any length of time it makes a loud screeching noise and then the picture is gone. It seems to cycle itself off and then back on and then the picture comes back. It repeats this at unspecified times while the TV is on. Also there is a humming sound coming from the back of it. Thank you in advance

Sounds like the power supply board has gone out. It can probably be replaced, but only by someone qualified to do so.

Loud buzzing noise which became a very loud screech over the last week. Turning tv off and on seemed to remedy it. Today screen was only black and white, now no video only audio. Is this the picture...

This TV uses a lamp and color wheel. the color wheel is likely the problem since it is known to make noise over time and will eventually sieze. The repair is in the $400 range.
