Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
When i turn on the TV a high pitched tone comes out of the back of the TV and is constant but varying in intensity
The problem could be that of coil that has become loose and is vibrarating cause your squeal . Or it may be a transformer in the power supply that is also vibrating . These can only be replaced to get rid of your problem and you have to isolate which one is causing the noise . Good luck
