RCA Model P52927 Won't turn on and makes a chirping sound
I have a 52" RCA Projection TV Model P52927 which just turned off one day and won't turn on. When I plug it in it makes a chirping sound, the sound stops when its unplugged. Hitting the power button doesn't stop the chirping when it’s plugged in.
Any ideas on what the problem could be? |

The set needs troubleshot and repaired looking for what is loading down the smps. |

Kip, any ideas on a good place to get the part(s). I am in Dallas, TX. Also any replacement tips would help a great deal. I never worked on a TV before.
