Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television

1 Answer

Power surge may have blown tv- Sony KP-46WT500- worth fixing?

I have a Sony rear projection TV model KP-46WT500 that is 6 months beyond the extended warranty! and I believe a power surge blew out the TV- made a snap noise and picture is now concave (small top/bottom in center and large on edges) and the 3 color guns can be seen "off" of each other. Can I fix it? Myself?

    No, sorry unfortunately not. But does the set look 3D? I would suspect that the convergence ic is bad.

My sony projection tv model # kp-46wt500 has a green and red tint. how can i fix it?


Increase the current flow to the blue color gun. If it is not adjustable it will need replaced and this is a major repair. You can try to reduce the red and green guns and increase the output transformer for a temporary fix, but save up your pennies for a replacement. Have a tech look at it before running out for a replacement because the SONY is the better model projection televisions.
