    I too replaced my convergence IC's but I still have the same problem with the picure convexed. (The top and bottom run toward center) I've read that a lot of this can be fixed using the PJE via remote but I'm not so sure it isn't something else instead. I rad somewhere else that there is a voltage adjustment in the front of the unit and I am looking for this post. Any ideas gurus's?

KP-46WT500 46 in. Rear Projection HDTV-Ready Television convergance adjustment


Try using the MENU button on your remote control to go into the TV picture settings menu. Change the mode to NATURAL, You can also try to manually adjust the color in the COLOR SETTINGS mode.

If that doesn't work, check out the handy troubleshooting chart in TV color problems and see if another solution will work. I hope this helps!

your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv

Loss of electricity due to the ice storm...


if it worked before and not after i would claim it, also sometimes if you complain to the electric company they will foot the bill on there insurance. power surge can cause all sorts of problems . just my 2 cents.
now this set is also know to have bad convergance ic
check this site out for repairing it.

By manual convergence, if you mean electrostatic convergence, then I'm not sure this is included in the service manual. However, if you join the http://groups.yahoo.com/sonyhdtv/ group, there is a file download called ws500tweaks.doc that documents this (with the usual caveats, like don't get yourself killed, when in doubt hire a pro, etc).
