Red and blue faded

Where to buy crt fluids and how hard is it to change

  • BigPossum Jan 31, 2009

    I was just given a 55" magnavox projection tv. The picture is great, but it seems to have a band of soft green and reddish orange areas through the center from top to bottom. The discolored areas are about 5 to 6 inches wide. During dark images they are hardly noticable but they really show when the screen is bright or light colored. It may be important to note that we transported this tv on a flatbed trailer over a very rough road. The tv was transported up right, but I'm wondering if we may have jostled something loose inside our is this another issue. Any advice would be greatly appreciated.

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. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

If so I believe your CRT liquid coolant has gone bad and needs replaced.
How to diagnose bad CRT Coolant:

Note: This problem will only affect the GREEN and BLUE picture tubes. The RED CRT is never affected, because the wavelength of the red light does not promote this algae growth
General Symptoms: Washed out, blurry picture, red portions mostly OK, GREEN images have halos, BLUE portions of images may have halos or be missing entirely.Turn the color level control all of the way down and remove the screen and/or the cabinet that contains the mirror. (different for different models) Do not turn the set off or the color level control will reset to preset levels. Look directly into the picture tube lens while the set is on. First look at the RED CRT. Observe the scan lines in the picture. These same lines should also be present in the green and blue picture tubes.
After looking at the RED CRT for comparison, look into the GREEN or BLUE CRTs. If it is contaminated, it will look like there is a layer of film that you have to look thru to see the picture. There may also be swirls and other various contaminates forming. If it is not as clear and sharp as the RED CRT, it is contaminated, and you should change the coolant fluid. IF you wish to tackle this I will supply more information and instructions. This task is medium to hard for non trained people.
Let me know if you wish to get the instructions on changing the fluid.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) 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. In some cases the TV will also not show any video. 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.

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( 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 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, 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.

Your TV has a burnt CRT base socket. Replace that, it is not a tough job, but make sure that you get the exact same type of base socket.

Poor color


You may need fluid change. CRT gets dirty fluid, must be changed after long time of use.

My tv seems to have more red and blue colors in it


It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.
