Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details for both. Repair kits with instructions are also avail from 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 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.

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

I have a 57" sony kp-57ws500 rear projection t.v.


the tv he mentioned is not plasma or LCD, it's rear projection with tubes.

brad, you'll have to take off the front panel. there are two phillips head screws behind two small round plastic covers, one at each end of the bottom of the speaker covers. remove those, lift the cover slightly, then pull down. be careful because the plugs for the front panel controls don't have much slack. unplug those and set the cover aside.

there is a rectangular cover to the tubes and focus panel. remove that, set it aside and you'll have access to the focus and alignment controls. the white markings on the knobs are factory reference marks. IIRC, the top is the focus and the bottom is the alignment. use a flashlight to check because it's marked.

make the adjustment as necessary to get a clear picture. =)
