How bad is it? Yes convergence can be a job. Remember green is stationary and blue and green is what you use to line up on green. More info ctechnicians.com

Sony KP-57WS5610 Blue light will not converge the blue is offset from everything else on the screen so its like a blue shadow Any ideas on whats wrong


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 www.TvRepairKits.com

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 yourconvergence 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 fromTvRepairKits.com . 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.

Lack of cool tones,seems to have pink tint where itshould be white? just got this tv from a friend today,trying to figure out best way to correct picture


Check the CRT fluid in the blue and green CRTs. It should be clear. These sets have problems with the fluid getting cloudy and hence letting less light through. It also gives it a dull picture look. If the fluid is cloudy, you will have to remove the CRT and replace the fluid. Then re-align the CRT via the convergence in the service menu.

My screen is discolored and blurry. Please advise..


Sounds like contaminated fluid. Each of the 3 crt's in your set have coolant to keep them cool. This coolant over time gets contaminated and causes extreme blurry picture. ITs extremely common on the Magnavoxs. Its also a pretty big job. Replacing the fluid isnt too difficult but because the tubes have to be removed it means both physical alignment and electronic alignment will be necessary. Also dont remove the green tube until you have done both the blue and red and aligned them to the green. Then do the green.. I hated doing that job lol.. I dont recommend you trying it and probably wouldnt be cost effective to pay a shop to do it either.. I recommend buying a new set... Sorry

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.

I have a 8P4834C 48in. rear projection tv and it had a green tint to it now it seems cloudy what gives


Your fluid in the CRT's ( mainly Blue & Green ) needs replaced. Not something you should attempt if you've never done it. A service company normally charges $250 - $350 for the whole job. The fluid is called Ethelyn Glycol, or antifreeze as we call it.
