Between 400 and 600 depending on the repair shop. However its a convergence Issue, If you can solder post your model number and I will post the ICs you need and a link where you can get replacements withfree instalation instructions with pictures and it will cost about 60.00 to do the repair yourself which takes about an hour.

From your pictures, I have a convergence problem and need a kit. Need to know cost for diy and a tv repair pro's cost thant you. I've had this done about one to one and a half years ago.. Maybe I...


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 and solutions 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.

Color problems!


if it caves in INTERMITTENTLY and you have a 3d effect you may have problem with convergence. you would need to resolder or replace convergence ics. STK392-570.
you would need to have some king od skill soldering and
unsoldering parts.let me know if you need more info.
if you take the speaker grill and the wood board behing it,(4-6)screws you will see the board in the center,big metal heatsink.
you would need work from the back in you want to replace them.
