    Hello, I have no video just sound on my P52960 52 in TV. This is
    chassis# PTK195Y06B. This started after I tried to fix an intermittent pincushion by re-soldering some caps and diodes in the power circuitry.
    While I had the card out, the flyback looked like it could use a little
    more solder, so to make sure that the flyback wasn't causing any
    problems I added some solder there. Now the tv turns on, or at lest it
    sounds like its on, and I get audio as well. The fly back seems to be
    very statically charged-I can see dust cling to the large red flyback
    wire, but the CRTs are not providing any light. I see someone mentioned checking the vertical output IC, but I don't have the schematic, any one know which chip this is? (The refrence designator on the circuit card would be most helpful) Thanks for the help everyone.

Whats the chassis number it should be located on the tag along with the model number. I will post a link where you can get a manual. I would check the vertical output solder. Try resoldering the vertical output IC see if that restores video.

Bowed Picture


This is a convergence problem. If you can solder, you should be able to repair this yourself. Please update this to confirm the model as P52960 and whether or not you wish to attempt the repair and I will supply additional details and instructions.

Rear projection tv broke


try resoldering the vertical output IC. This is a common problem the tubes blank out but sound and on screen displays still work 90% of the time its the solder connections on the vertical IC that causes it.

The clicking repeatedly is the relay clicking on and off due to the power button being pushed in. You are having problems with the start up circuit. Probably minor but you would need a service manual to actually diagnose the problem . Let me know if you would like me to post a link where you can get the service manual
