TV has RED and GREEN colors distorting the color output of the TV. Can not simply adjust color and hue. Red and Green still remains controlling and dominant. How do I fix this?

If it does this on all inputs then it is the tv itself. You can try different sources and cables to see if the problem is not the tv. If the problem is the tv I would suggest having the tv repaired. It looks like a nice unit so it would probably be worth fixing. I would find a reputable local shop to take it to.

Picture has a white hue. Is this a bulb problem and if so how do i know which one

projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Information on seeting convergence for 50hx81 tv

In the customer menu select convergence with the Toshiba remote.

If it is skewed and or will not adjust you have a convergence circuit problem. If this is the case let me know and I will tell you what is involved to repair the set.

I have fixed hundreds of sets with this kind of trouble.

Picture looks like 3D. The writing and picture look like they have a doubled effect

This is a convergence problem that can be as simple as poor connections at the convergence ICs or defective ICs. If you can solder and are comfortable working inside the set, you can probably repair this yourself. If you wish to attempt the repair, please confirm the model number so I can give you the part numbers and I will update this with additional details and instructions.

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:
