Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television

1 Answer

Picture is yellow

We just purchased this TV from a friend. The picture has a yellowish tint to the picture. When watching a program with a lot of green, it seems like you are looking through Blueblocker sunglasses. I tried adjusting the settings and ran a convergence on it with no real change.

Re: Picture is yellow

Your picture tubes are weak or you need to do whats called a grey scale adjustment. In other words you need to put on a totally B&W movie or test pattern and adjust the red , green, and the blue screens to the best B&W you can get. Then you need to adjust the CRT drives to the best grey scale. If you do not know what this is, I'm afraid you should call out a pro to assist you with this alignment, as if you go messing around, and do not know what you are doing, you can make the set landfill material. Not for a novice to do. Good Luck

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.

I have the Sony KDS- 60A2020 60 inch TV. Recently, my picture has appeared more yellowish. Everyone on it looks like there dark yellowish or have fairly dark (bronze) sun tans. I changed my lamp yesterday...

I have a older 2006 SXRD rear projection TV. I had the same problem after the TV warmed up this yellow tint started in the corner and crawled its way down the TV. It turned out that Sony had a recall on the optic block of the TV. If you replaced the Lamp and adjusted the color this kinda sounds like the same problem. Here is a link explaining it. In this article it shows up as a green haze and blob, but in my TV it manifested as a yellow tint.

The whites are yellow and theres a yellow tint to the picture in general although not real bad. Is this just the lamp # ux21513 needing to be replaced? Thank You

The Lamp would cause the picture to be dimmer but not discolored. I would suspect the Optical Engine is causing the yellowish tint. Due to the cost of replacing, call Hitachi at
1800-448-2244 and see if they would be willing to help with the repair.
Hope this helps,

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.
