Hooked up PS3 to system and when watching DVD's the right side of the picture is blurry and appears doubled, like an old 3D movie without the red and blue glasses. When watching TV everything looks fine.


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.

Picture of a set that needs the fluid changed.

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

How do you fix a 52" hdtv ready when its in 3D blurry format


This tv doesn't have 3D capabilities - the image appears blurry because both images are displayed on the same screen at the same time. Just don't use the 3D option from the BluRay player, view the movie normally - 2D.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Blue is mis-aligned.


You need to replace the two convergence IC's - part# STK392-040. Also look for burnt/discolored resistors near the IC's
