Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

Further assistance needed


I just replied you and here once again...

Please pull front speaker grill and find focus block, fixed at corner having 6 control knobs on it.
Find Blue Screen control knob there.
Put your TV in AV mode to get dark screen and just press Display button on remote to have AV display.
Now slightly rotate control knobs counter clock wise until thin lines (retrace) disappear. Job is done and put back speaker grill, press display button again to disappear screen display.

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 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.
