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.

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

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.

Green hue/tint


Need to do the alignment feature where it refocuses the light beams. Convergance. Look through the set up. Different magnetism and shaking of the set has thrown it off most likely. Auto focus maybe what its called.

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.

Greenish yellowish tint on the tv


I have been advised that the color/light engine of the TV fails often and will typically create a green tint on this unit. I have one on order to get a replacement installed. BTW, it is not "user serviceable" and (for me) will require moving the TV to the repair shop for the change-out.
