IF TV is a CRT, the high pitched sound is caused by a faulty power supply unit, or a faulty deflection circuit.
If TV is an LCD, the chirping sound is often caused by a blown electrolytic capacitor melting and leaking internal fluid. This happens often with PSU capacitors.
Whenever this happens, do not try turning on the TV, or you can cause more damage to the set.
The TV must be disassembled and tested , starting from power supply board. Often it is possible to spot the leaking capacitor at a glance, it will be burnt, bulged, and leaks are often visible. The repair must be done by a technician.
Call the support number printed on your owner manual, or locate a local repairman.

CHIRPING SAMSUNG PROJECTION TV


Chirping is set is in shutdown---most likely in High voltage area of set.

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.

Rainman, can`t really be of any great help on this one, both techs can be right, the chirp is exactly as you thought, the set is trying to come on but there is a short in the set and it`s shutting down because of the short, could be convergence, low voltage power supply, high voltage power supply, until a tech gets in there and starts un-loading circuits it`s impossible to say where the short is, gonna have to call someone out for this one, good luck with it, BMW Rider

No power just a chirping noise.


Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC

Tv went dead while viewing, will not power back up


You have a short somewhere in the load for the power supply. Probably the horizontal output transistor and the flyback transformer. You need to have it checked out by a tech. You may want to get an estimate. Stargazer
