RCA P52921yx2 WIll not power on only clicks

We have a 52 inch rear projection RCA TV. One day it just shut off while watching it and would not turn back on. It makes a clicking sound when it is plugged in that stops when it is unplugged. DOes anyone know what this might be and or how much it might take to fix it?

I own a 52 inch rca projection tv and last week

Most likely the Horizontal output transistor has shorted. When it shorts it causes the power supply to chirp. This is a common problem with this series of TV. Have a shop check it out. It should not be real expensive.

Your TV is overheating.. easiest remedy is to point a fan at the back of the TV or... clean the inside of the TV, Im sure its full of dust and stuff... this prevents air circulation inside the TV thus creating more heat...

You have bad convergence IC's.. If your not experienced in troubleshooting electronics or soldering, you should have a trained tech take a gander at the set. Its not worth risking life and limb to save a few bucks, Good Luck
