Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television

1 Answer

Convergence i have a Sony Kp-46wt510 that is about 2 years old. It has been working fine until about a week ago. When we turned it on in the morning, after it was off all night. all three colors where out of convergence. I tried flash focus with no results. When I go into the manual convergence mode the screen comes up but I am unable to move the colors. I know just enough about electronics to be dangerous, but if pointed in the right direction could possibly fix. Any suggestion would be greatly appreciated.

Re: Convergence

You need to go to, enter your model number,look up under that model number STK #(@-560. Order Two of the part number 874901908. These also need heat sink grease in the back of these ICs when they are replaced. If you know how to solder, then good luck, and please be carefull!.. Please do not forget to rate this thread.

Whole Screen Turns Blue in seconds....

This could be a problem with the Blue CRT it archs or overdrives intermittently. I would have a technician test the set and give you an estimate - if it's the CRT it's usually not worth repair- but it could be video or a screen voltage related problem. It's worth the estimate.

3 blinks means the convergence circuits are shutting the set down. Usually the convergence ICs will take care of the problem, but I would recommend getting the service manual from the following link, as they will provide you free support to help you diagnose why it wont start as usually the convergence ICs wont prevent a set from powering up, unless another component in the convergence circuit has failed.
