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

When I turn on my TV, the power light just blinks green but I have no picture or sound. I am not sure that my sound problem is not related to the fact that my DVR may have ended a program and just is not playing. In addition, I hear a chirping noise that lasts about 3 seconds that occurs about every 30 seconds.

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.

Hi,

Green light blinks but no sound no picture


Power surge will knock out picture and sound if you don't have a power strip. Found out from Best Buys when purchasing another LCD TV. They have a warrenty against such problems.

The power comes on and then turns off and the front green power light blinks.


There is a small IC in the power supply section,
not the IC regulator that's the problem.

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.

Flashin power light - wont come on


The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
