    Would dirty mirrors have an effect on the color?

  • aasingle Oct 04, 2010

    I have used the remote and I tried to adjust the tint--it did not seem to do any good. This is a rear projection TV so I wonder if the mirrors are dirty. I don't feel safe taking the back off.

This is a CRT projection tv - one in which the colors are generated individually by some small tubes. If the refracting lenses would have been dirty you would have seen a general loss of image, not what's happening here.
In your case the tube that emits the green color has aged and doesn't emits so well. So when it's supposed to emit on its own (like when you see a field or any other green object) it can no longer do it 0 and the remaining colors (that also emit a little) there take precedence and change the color.
Since this is caused by old age it can't be fixed - the tube must be replaced. As a precautionary measure you should replace all 3 tubes, the other 2 can't be in a much better shape.
This is a shop job only - the adjustments for the new tubes must be done with special equipment - and it will cost you about $500.

    yes dirty mirror has effect on color and picture quality.dirty mirror and dusty lamp will produce a blured picture you need to wipe off the dust accomulation atleast twice a year.It is not dangerous to open the back cover as long as you unplug the unit for the outlet.Just remove the four screws at the upper cover not the bottom cover after removing the cover you can easily reach the lamps and the mirror use a soft clean cloth to wipe off the dust.do not youse excessive force this might break the glass.after cleaning do not return the cover plug inn the tv and power on and check if the green lamp is working if not then you need to check the pcboard of the green lamp or the itself is busted.or the signal from the SIGNAL from the CPU is

Hello. Turn on the set, get a picture that has brown grass and then go into the menu, select the color function and make gentle changes in the color until it is more to your liking. J.

RCA D52W136D 52 inch has no green


Hello sjustinh,

It sounds like your color processor may have gone bad or at least the circuitry connected to it. To solve this problem you will need a schematic, a digital storage oscilloscope, a signal generator, and a multimeter. Now if you don't know what these devices are and do not have a background in electronics, I would suggest that you take the TV set to a qualified TV repair person. I am not trying to put you down or anything its just that this problem requires that you open up the set and using the schematic trace down the signals that control the LCD screen and find out the condition of the signals that display green. Since green is the result of the algebraic addition of red and blue, you may have a problem in the circuitry that controls that function.

I hope this helps,

Thank you,
