How do you adjust color on a RCA D52W20B other than the remote?

Are you running component input on this--If so, make sure the red cable has not worked loose or gone bad.

Samsung dlp the picture is all shadows with dark green/black colors after replacing with new color wheel..what is wrong? Is it a bad color wheel?

no you need to adjust the color wheel to factory specs by getting into the service software. The color wheel has to be timed to the engine.

My tv will work fine for say 1 minute then keeps flashing green and shuts off i have looked up the code it says its the D borad thats gone bad is there a wasy i can self fix it.

The "D board" is the flyback transformer, but if it was bad, you would have no picture at all. Here is a proven method to get it to work (for a while....)

The adjustment method is to put the set on a video input with nothing conected
to that input. Turn the screen control up slowly until those fine lines appear
and then down until they just disappear. Do this with all three colors. You
might need to turn one of them down a little initially if the set won't stay on
long enough to get to adjustments. You cannot do the adjustment on a TV station
or on live video input. If the adjustments are too high, the set will turn
bright and shutdown. If they are too low you will never get a picture at

You would want to touchup the adjustments after a warmup of a few
hours, then recheck the next day when cold.

If the adjustments are
successfull and the set stays on but the color reproduction is very poor then
one of the tubes is probably bad.

If you are lucky and everything turns
out OK, you will probably need to do it every year or so.

How to adjust the picture, convergence is wrong on a 55'' prejection TV

If you cannot move or align the colors with the customer convergence menu, one or both of the convergence amplifier IC's have gone bad. These IC's are located on a common heatsink on the left side board looking from the back. It would probably be best to have a shop check it out for you. This repair can lead to a pretty in depth convergence adjustment. Fairly complicated. Thanks for using fixya.

Why cant i manually adjust the color convergence

The thought is that the Amplifier that controls this color has gone bad. If you tweaking the Global L&R Horizontal knob and nothing is happening. Then the amp is shot.
May have to replace the Amp or the whole board.
