That is usually caused by the horizontal output cisrcuit or the flyback. Can you post the chassis number as RCA has to be diagnosed by chassis number.

No picture, no sound, just chirping noise coming from back


NO - - signal did nothing to the set... Sounds like a shorted HOT (horizontal output transistor) and the feedback your hearing (chirp) is on the horz. transformer as it tries repeatedly to startup... Don't allow it to do that for too long...

No picture or sound - TV makes chirping noise


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

Green Power light blinks but no picture or sound with a chirping noise


That chirp is your ballast trying to fire the lamp. Sounds to me like you need a new lamp. The model should be TY-LA1000. Keep in mind though that the ballast could also be faulty, but 85% of the time it's a lamp. Pull the cover off the unit and remove the lamp. More often than not, when the lamp goes it'll actually break and be obvious.

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.
