Question about RCA P60921 60" Rear Projection Television
When the TV is plugged in there is a distinct chirpin noise. The TV will not display a picture or sound. The TV is an RCA projection TV (model P60921YX1). No repair activities have been taken at this time.
Rich that chirpin noise is somthing over loding it try checking your horzotal output for short and diodes around the transformer...

The chirping sound is the power supply trying to come up, but can't due to a short or other condition. Open up the set and see if there is any obviously bad (burned) components.

The chirping sound is the power supply coming up then breaking down because there is a short somwhere in the high voltage. The most common fail in this area is the horizontal output is shorted ( 237470 ) but what cause this short could be simple cold solder joints or the High voltage transformer ( 239111 ) If you have noway to "ring" the flyback change both parts
