Get an ESR capicitor meter and check for dry or blown caps on the convergence board - replace the 2 convergence ICs (but ONLY do this if you are electronics qualified - or get a tech to do it). Clean the lenses of the tubes - these come completely apart and you can change the fluid too - usually this is a $250 per tube job (there are 3 tubes) for a tech but you can do this and replace the fluid yourself which will clean up the fuzzyness. Then reconverge and do the flash focus for all zooms (you may have to do this several times).

Here is a link too for the service manual which details how to converge your set - http://tv.groups.yahoo.com/group/Ws500/

Lookslike the picture is in 3d and when i try ti use magic focus


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 photos of convergence problems.

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

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. =)
