My tv has a red tint to it not sure what to do?


Projection 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 video.

Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

Patchy color printing, streaks and dull colors using Phaser 8200


I have the same exact problem. I just switched to a mac and the colors are awful. I tried from 3 different macs at work, trying different combinations of color profiles, settings, etc, and the colors always look completely off. Blues are magenta, bright red is a dull reddish, orange is completely brown. It looks like Xerox decided to not even try to make this aspect work with the Mac. This is on the latest Mac book Pro, running Snow Leopard, to a Xerox Phaser 8560 DN.

My tv is showing alot of red with blue blotches across the screan


Your TV most likely has fone of two possible problems.

Problem #1 - Failure in the convergence circuits. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

0667c5f.pngSOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

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.

Projection tv


the blue gun is not working properly which explains the dominance of green and yellow colors. you need to look after dry-joints on the blue gun circuit board, sometimes oil leakage from the lens may also affect the board

Dull color


I would say phone or email Kodak as you may have a faulty printhead. If Kodak sayes you have a bad head they will airmail you one overnight and throw in free black and color ink tanks all free of charge.
I have read that some how in making the printhead a run got too hot in process and thus a bad printhead.
Hope this helps
