Mits. rear projection tv ws65905 picture has blue color tint

Your blue picture tube is failing. Invest in a new TV. "If" you can find a new set of tubes(you have to replace all 3 red blue and green) they are around $800-1000. Not cost effective. Run the TV into the ground if you want to wait but do not invest any repair money in my opinion.

My blue and green coloring is messed up on my Mitsubishi Medallion. I can't get it to have both colors normally, it has to almost be one or the other. Is this just a contrast issue, or something

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as

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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from . It includes replacement parts,step by step instructions, support, etc.

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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from . It includes replacement coolant,step by step instructions, support, etc.

The liquid in my mitsubishi rear projection tv just came out of no where once i started to unscrew one of the color tubes...... does this sound right or make any sense??

Yes it does, you should not unscrew the red screws only the gold ones in the corners of the tube.
What is the symptom of the problem that you are having.
You will need to ensure that all of the liquid is off of the circuit boards as soon as possible as it will wick under the IC's on the board and quickly ruin them.

Please let me know if you need more help or assistance.

Mitsubishi lamps

This set does have a lamp, it utilizes 3 picture tubes (red, green, blue) The tubes are not available as new any longer. It is recommended to replace all 3 after the reaches 5yrs of age because a new tube will over drive the others in brightness but it is possible to only replace the defective one. You can try Tritronics at 800-638-3328 for rebuilds.
