Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

Picture Color My RCA D52W20's picture color has gone towards a yellow tint. Things that would normally have some red in them have become bright yellow and the whole screen has a sort of yellowish tint. I believe that possibly the red tube is burning out/misaligned/broken. Does this sound correct? If so, where can I find to correct parts, and is this something I can fix myself? If so, how?

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.


Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

Adjusting to the proper color

Tint would be the control that will control the color balance, but this sounds like it may be deeper then that. Turn your color all the way down so that you have a black and whit picture. If the picture is still yellow then you have a problem with the blue picture tube.

I have a RCA 42 inch 1080 HD Tv. My son decided to change my color setting. Is there a way to get the factory setting back? I have been playing with the different tint, contrast and color settings. I still...

well there is usually a tab in your pictuer adjusment screen that says reset. but if your tv doesn't have that tab i can give you a few adjustments.

first- your tint should remain neutral. so if it has a color scale of 1 to 100 it should be on 50
second- your contrast should be about 80% or what your eye likes. look at the black tones
when you are adjusting it.
third- your brightness would look good about 65% pay attention to whites in your picture
fourth- your color all depends on how your eye precieves it. so adjust it with out making the colors to
neon or too dull
fith- your sharpness should be turned down to about 15% to much gives the picture a grainy texture.
sixth- your color temp should be neutral or normal. if the tv gives numbers the selection that says 6500k is the best choice.

you could always buy a calibration disc for about $20 and that could help you even better because now you are using images targeting the individule adjustment.

you could always pay to have it profeesionally caibrated. ISF certified techs will come too your home and do all the adjusment with special color filters and light sensors to give it the best picture possible according to your room. i know best buy charges $250 for it

those are just some suggestions. and the adjustments i give you work greatest for me, so if you dont like the overall out come you can always tweek it to your eye. make sure you use a digital picture with a lot of color when your making your adjustments. i like using disneys "the incredibles"

Sounds like your convergence chip has gone bad. Usually costs about $300-$400 to fix. I would call a local TV repair shop and let them give you a free estimate.

Color problem

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
