I would suspect the convergence IC's are bad, look for STK392-110; replace.

Picture seems sunk in and the color distorted with doubleing effe


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 projeciton 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

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Picture is distorted from center on my 65


You do have a failure in the convergence circuit of your set. If you are good at soldering you can replace the IC's yourself. They are on the large circuit board on the left side of the set looking from the back, and attached to a large aluminum heat sink. If you don't feel comfortable doing that, I reccomend removing the board and sending it to PTS corp in Indiana. They are pretty reasonable repairing boards, and a lot less than buying a new one.

Sony, tv comes on color fine, then turns red


I had the same problem with my TV, but the hue was blue. I was told that not only did I have to replace the picture tube that wasn't staying on, but I would have to replace them all because they would not mix properly. After much investigation, I found that there is an adjustment for a variable power supply to each tube that can brighten and lighten each tube. I adjusted the RED pot and my picture color issue was resolved! To access this adjustment you must remove the front panel on the TV. At the bottom corners there are two small screw covers that you must remove. Then un-screw the screws under the covers. Then pull the front panel off of the TV, (it hooks under the top near the screen so it will swing out from the bottom). Now remove the wooden panel in the center, (four screws). The pot adjustments are at the bottom of the TV. They are marked for Red, Blue, and Green. They are extremely sensitive, don't turn them much! If you over adjust you will get red, green, or blue lines on your screen. Adjust back down to remove these, (this is also the remedy for removing these lines that can appear over time). Good Luck and God Bless!

Part disclored picture


as it has fallen on the floor

due to that its deflection coil position might  have  changed a little.

due to that its left corner has gone down.

 

deflection coil has convergence magnet on it so due to that there is change in color also.

 

please call tech to re position of deflection coil every thing will be fine as it was.

as per buying another it is up to you.

hope this will help.
