The convergience is off(screen is different colors) &I don,t have the remote that goes with it (broken). Where can I get the remote for the tv because a universal wouldn't work?


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Picture like it is in 3d when i try to adjust the convergence the plus signs on the left are bent


Set uses two of the STK-392-110 chips and board they are mounted on is easy to get out---On EBAY a pair will cost about 12 dollars. Total parts cost should be under 25 dollars. I can tell you best way to get at them and replace them.

See attached photos--this is board in your set with the chips--black in color and number right on the front of them.

Convergence


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.

e87380c.jpg
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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Bent picture


Not sure if you fixed your problem already. But the answer is a color convergence problem. You can try adjusting manually via the remote and if that doesn't work it is most likely the two main IC chips that control the color convergeance. It is also possible that not only the IC chips have gone bad but also there are a couple of resistors that usually burn out with the ICs as well. They will need to be replaced. This isn't something that I would attempt on your own. Typically a TV technician will charge between 300 and 400 to fix at your house.
