RCA p46732ba projection TV no power.

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.

G36710 RCA console TV just quit while watching... makes noise

a shorted horizontal output transistor will make a funny squeek or chirp noise when turning on the tv. Usually mounts on a metal dissipator near the bulky plastic part with the red thick wire coming out of it.good luck!

TV makes chirping noise, won't turn on!

That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.

My 52 in

Chirping is usually a problem in 2 areas of this unit. 1st check 3 legged regultor on the right side of the chassis, also 2 small transisters and 2 resisters near and in front of the regulator. RCA has a kit for this problem, the second is check the horizontal output transister is on a separate heat sink along side of the Flyback Transformer, it shorts and pulls down the regulator power supply.

PT-43LC14 No Picture, chirping sound when turned on

Most of the time, when there is a chirping comming from a TV set, there is a short somewhere inside the TV set. That chirping noise is the TV's power supply starting up and shutting down because of a heavy load on the power supply. These sets have no user replaceable parts inside them, so play it safe, and call out a pro to assist you in this repair. good Luck PS Please do not forget to rate this thread.

If the set trys to turn on and makes noise three times then you hit the switch again and it will try to come on again churping three times , its a shorted horizontal output transistor and a bad flyback transformer. And Im sorry to tell you the transformer is no longer available according to RCA. Its a shame. I just threw out a 56" and a 32 " set that needed a flyback and could not get them.. Well good luck ps please rate this thread.
