Banding on screen


Since this TV is still new, it's much faster if you exchange the unit at the place of purchase and get a new one. You can also call Sony at 1-800-345-7669 (SONY) and get it service for free.

Rainbow colours on the screen


The projector is starting to go out in it. Depending on your financial situation, you can take it to a shop to have it looked at, or replace the TV. Depending on how long this has been happening, the Pioneer projectors usually last about 100 hours once this happens before they burn out completely.

The green is taking over all the color on the tv

I have the same TV which had the same issue ( green in picture ) - back on 10/2007. I called Sony. They had their technician replace the optical box ( factory defect ). There was no charge for the repair even though TV was out of first year of warranty. Call Sony.

Colors no aligned


Hi Chin,
Please check faded color resistors (in big size) on D board and also check dry solder joints on D board.
If above seems OK then ICs STK-392-560 are suspected and needs to be replaced.
Let me know if you need further info.

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.

Sony KP-57WS510 rainbows and arches


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.

TV shadows


Check the proximity of magnetic fields. Large Speakers near the TV for example will cause colour distortion.
