If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

I have a sony widescreen projection tv model KP51WS510. the picture has shadows and shows double.


Thats caused by failed convergence ICs your model uses the STK392-560 ICs you will also need several 3.5 amp pico fuses and a couple of 5 amp pico fuses to do the repair. The Sony Type 1 convergence repair kit is the correct kit for your model. It contains the parts and the CD with repair instructions. The kits available from www.tvrepairworld.com

I have a sony kp-51ws510 projection tv, i replaced the convergence ic's and a pico fuse and then reset the convergence. The tv looks good except for a green shadow on lettering, also on the convergence...


Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

Blue spot


the model number KP-51WS510 deosnt use a bulb or lamp. and touching the face of the lamp will not cause color problems in the picture. if your tv is an LCD projection then i would suspect the optical engine as the culprit. to check when you turn the tv off do you still see the blue distortion? if so then you have a bad optical engine.......as long as it is an LCD projection.
