I am asumming you are talking about you changed the convergence ic's. If so look at the solder connections made on the IC's , if any of them are bridged or making contact with another pin next to it then the television will see this a short circuit, and the set will not stay on.
Also if the plug your friend unplugged is going to the area of the ic's then check and recheck your solder connections.

Thanks

NO picture NO sound, chirping 60pp9202


Chirping isnt caused ny the ICs and resistors. The chirping is usually caused by the Flyback ( HV Transformer) or the HOT transistor.

Hitachi 43UWX10B 43" Power Light flashes Continuously


I doubt if its the fuse. We just helped a customer with a very similiar problem. Its more likely that the convergence IC have failed and shorted out. When this happens one of the symproms is that the TV will shut down and chirp. Goto www.TvRepairKits.com and click the contact us button. They can provide you with more instructions on how to test if this is the problem.

Tv has no sound or picture just chirps


Hello hoggsnob,

This problem denotes the startup sircuit trying to turn on and the shutdown circuit trying to shut the TV off, the result is a on-off switching of relay circuits which causes the chirrping sound. The cuase of this issue is usually the convergence ICs have shorted or the Horizontal Output Transistor has malfunctioned (shorted). I would suggest checking the HOT first and then the convergence ICs.

I hope this helps,

Thank you,

TV MAKING A CHERPING OR CRICKET SOUND AFTER IT IS TURNED ON


Two main common failures for these sets is the convergence amps and the flyback transformer (which is rather expensive). Both can make the set "chirp".

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