    Yes that model uses two STK392-560 ICs you will most likely need a couple 4.7 ohm 1/2watt metal film resistors also. You can get the replacement ICs and resistors at the following link and they provide instalation instructions and free online tech support when youre doing the actual replacement. Here is the link.

SONY PROJECTION TV MODEL # KP-51WS510.


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.
