I assume it is rear projection TV so want to know how old is this? If it is rear projection Tv then either green gun drive over gain or red and blue are less drive gain. Problem can be set by adjusting Screen Volts of all 3 guns in TV to produce correct white balance for fine colors. If you have no experience of TV repair then ask help by qualified TV tech.

Hi and welcome to FixYa,

Initially, pls postback the exact model number.

Offhand, this could indicate that the green is overdriven and drowning the other colors, red and blue.

Good luck and Thank you for using FixYa.

Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint


The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

What causes the yellowish hue in the centre of the screen


There are several different types of projection sets: some use 3 picture tubes, red,green,blue--if this kind of set is what you have the coolant used in the blue tube is bad-----this type of problem leaves red and green which = yellow.

Most common in Samsung, Philips, Magnavox type sets.


If it is a newer set without picture tubes (a dlp style set) yellow in the middle of the screen would denote a damaged optical light engine.

Let me know brand, model number, date made----all are on back of set.

How do I replace the blue tube and is it worth the cost?


Hello, It has been my experience that once you replace any one tube of a CRT projection tube TV, the CRT that has been replaced will have more emission and it will reflect in the picture quality, I mean that there will be more definition, brightness, contrast in the blue images in the overall picture than the red and green, it will also show up as excessive in the overall gray scale adjust.

Looks like 3D tv


Try doing a calibration. Projection TVs work with 3 picture tubes (Red, Green, Blue). The Red may be off to one side causing the hues.

The manual is available here for instructions on how to perform calibration:

Blurred TV - double vision with red hue


I was searching online about what could be the problem with our TV and I came across your page. We have a 52" JVC Projection TV that now has a "blurred" screen. We can see the channels but it looks like it's has a shadow around the images. The screen in in a red hue with green blur.

If you have any suggestions on what caused this and what we can do to have this fixed, I would greatly appreciate your advice.

Sony kp-57ws500 green screen then auto shutoff


I have the same tv and it did the same thing only now it has red hues all around the picture as well. The service guy told me it was the green tube and it would be about $500.00 to replace and may not fix the problem. What a p.o.s. I will not be guilty of buying any other Sony products from now on.

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.
