Sony KP-57WS510 rainbows and arches

I'm getting rainbow colors and arches on my screen for the second time. This happened last year when the tv was still under extended warranty and now it's happening again. I have the old parts the repairman took out of the tv (STK392-560). I've found them online at www.electronix.com but they are a little different shape (mine are a hexagon). Does the shape matter?

No the shape doesnt matter as long as the STK numbers are the same. I would make sure that the replacements are origional sanyo ICs as often the cheaper versions do not last very long.

Sony KP-57WS510 57 inch rear projection - Rainbow colors and arch


hi, you`ve lost your convergence ic`s, unless your very proficient at solder work I`d advise you call a tech, will require removing 2 large IC`s and possibly a few small support parts, resistors, chemical fuses etc. Every place is a little different but runs approx. 300.00 at my shop, gl, video-tek

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

Sony KP-57WS510 57 inch rear projection - Rainbow colors and arching


Same thing happened to me. I had to get it fixed. They said it was a "tube".

Now, my problem (7 months after getting it fixed) is that it suddenly seems a lot dimmer. I'm not 100% sure, and was wondering if there was some kind of diagnostic to run to find out for sure.
