    I have a ge widescreen there is a clicking sound even when tv is off

  • Upallnite Jan 18, 2008

    My RCA P60921YX2 only chirps when pugged in and continues for a bit even after unplugging. I noticed that resistor R14512 is fried but the bands have burned off. Any idea of th value? Is this possibly the whole problem?

    I have the same problem as upallnite. The resistor R14512 has bands burned off and power supply makes chirping. Has anyone fixed this problem? Is this a bad flyback or something else?

The chirping sound is the power supply trying to come up, but can't due to a short or other condition. Open up the set and see if there is any obviously bad (burned) components.

SOURCE: 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

My eMachines W4685 PC Desktop keeps making a chirping sound like a cricket, and a small orange light blinks in one of the ports, in the back of the tower. my system will not power on until the chirpin


It doesn't start at all? It can be that your Ram is faulty and the chirping is coming from a little speaker on your board, I had the same.
Else it can be the cpu-fan, but in sync? I doubt this.
Check your Ram.

Tv does not power on


u have a short on one of the secondary voltages from the power supply. commonly a bad diode.
the chirp is the supply attempting to start into a short.

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...
