Question about Televison & Video
I have an RCA p46732ba projection tv, and it will not power on. All i get when i plug the power cord in the back is a chirping sound for a few seconds. There is about 15 quick chirps before it shuts off. If i unplug then plug it back in right away, the chirping noise won't be there. In order for it to chirp again i have to leave it unplugged for about a minute or two. The noise is coming from a spot a couple inches in front of where the power comes in on the same main board.
This is a common problem and the set is in shutdown mode. It attempts to fire up three or four times (the chirp you hear) if it detects a fault it shuts down - the most likely cause is the HV (high voltage) block- caution working on it since HV is present - The repair generraly costs $200-400 P# 205064
Google your model # and HV block to see what I mean.
