It most likely is your convergence the part# is stamped on them. you can identify them by the large heatsinks they are mounted to. on the sony TV you may also have some fuses & resistors that may be open also.
The following web site will direct you to the Sony convergence repair kit for your TV:

I have a kp-51ws500, that comes on the colors get wierd then it shuts off, any ideas? Lamp?

Not Lamp, it is problem of convergence output ICs failure. KP-51WS500 is rear projection tv that has 3 color tubes to make picture, this tv does not have Lamp as light source in DLP tv.
Replace convergence output ICs to fix the issue. Local tv repair shop will help you if you have no experience in electronics stuff fix.

Colors out of alignment; curved lines

Marilee, you will need to check on the service manual schematic of what types of voltages you have on the IC's now. Most of the time, there are whats called pico fuses that blow out when the convergence IC's blow out. They are located on the G board, and are yellow in color. They look like small resistors. Check them for continuity after you replace the IC's. By the way, did you use good replacement IC's for the convergence? There are all sorts of aftermarket types and factory rejects being sold out there via the web or from local electronic parts distributors. Make sure they are the original types. If you know how to read a schematic diagram, but do not have the service manual, let me know, leave an e-mail address, and I will be happy to send you some info on the replacement of the ICs as well as the factory service manual. Good Luck!

Try this....

These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

KP-51HW40 - Picture not Clear

Your problem is a typical convergence problem that happens on almost every tube type projection TV set ever built. There are two Convergence amp IC's that need to be replaced. If you have no TV repair experience, play it safe and call in a pro to assist you in this. Good Luck
