Question about Sony KP-57WS500 57" Rear Projection Television

2 Answers

The 3 colors are off, i have shadows and arches in the screen

Can anyone tell me what is wrong and/or how to fix this problem. The picture arched up in the middle from the bottom and arches down in the middle at the top. There are shadows on the screen, and the colors are messed up, for example, when there was a picture with a pole, I saw three different poles, one blue, one green and one red.
I took the front cover off and tried my best to tune the knobs.
Any help would be greatly appreciated.

    Would the D board be located inside the front, behind the speaker grille? I think replacing the ICs would be easier and less expensive than replacing the cartridges. So how do i find out what the STK number would be? Do I look at the ones currently in the TV set?

    You can have access to D board by taking off of rear / back cover of TV as D board is located inside TV.

I Have a major convergence problem. It is a 55 inch Toshiba ColorStream Projection TV(tp55h95). It was fine until we moved it into the other room, and now it's like the color is bending at both sides of...


Color arching.... Ahhh Yeah they eventually do that after a few years. Good news is all you need is a screw driver and some of your time and patience.

The color gun is a small box with 3 screws on it. (Blue, Red and Green. Turning the screws (Slightly) on the gun will get rid of the color arching. I had blue arching on a sony 65" Rear projection a year later it was red arching if you leave it long enough it will be arching and in and out flashing of solid color. Whole mind trip you don't want to venture on.......

The box on my sony was in the very front of the tv. I removed the front speaker panels and accessed it very easily. The hardest part is getting the front panel off. Yours may be in the back.

Best regards and Semper Fi...

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

Picture Falling with arch


It is your convergence IC's going out, they cost about 40 $ for both, if you know someone that can solder, i would have them do it, once you see the new parts it is prity easy to find them on the board in your tv, repair shops usually charge 4 to 5 hundred

Screen shadowing with colored lines


This is most likely a convergence problemand can easily be fixed. If you can solder you can repair this yourself. First try resoldering the pins on the convergence ICs. If that failes to resolve the problem, replace the ICs. THese are large black Ics attached to a heatsink and may be marked STKxxx.

Keep us posted.
