Sony KP-65WV600 10/26/2002 rear projection TV. Blue gun went out and glows orange. Convergence chip is out (can not adjust convergence). Sony refuses to help saying my model is not covered by any offer....


The convergence repair if done is possible do it your self; If you have also a bad blue picture tube or some issue related to the tubes then the set is beyond any reasonable repair.,

not always easy to replace a set that cost in its day a lot of money but it is now about 9 years old and that is about average to this type of set.

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

The tv works but the picture is distorted all around the outer edges of the screen, and what you can see looks alittle blurry.


This is a convergence problem. you can try to re converge it with flash focus button on TV or in the menu if there is an option for convergence or focus. If you get into this menu and the lines will not move in all directions to line them all up you will have to replace I/C chips on convergence board inside TV. Do you know how to solder? if not this type of repair will typically cost $300 to $450 for a repair man. Let me know if this helps. Please reply to this solution if you have further questions or need assistance replacing I/C chips. I can help walk you through process if you feel comfortable with soldering and circuit boards. If you feel you can repair yourself with guidance from fixya should cost less than $50 to fix.

Convergence point problem on a Philips TV


The 55pp9352 model number uses 2 of the STK-392-120 convergence chips--if it will not adjust in some direction--both chips and any of the 6.8 ohm resistors around them that are bad need to be replaced.

The reason this happens is the chips are about 2 1/2 inches wide X 1 1/2 inches tall with a metal back--they are attached to separate metal heat sinks and a white grease is applied to each to transfer heat quickly---after several years the heat sink grease dries out and one of the chips cannot stay cool enough and fails.

Pretty common problem in ALL rear projection sets--if model is 55pp, it is 55 inch set.

You can buy the chips on Ebay for less than 12 dollars---the resistors if needed are cheap parts.

It depends if you are able to do the repair yourself or need to have someone do it for you--most shops get at least 300 for this kind of repair--considering the parts cost less than 20 dollars if you can do it yourself you can save a lot of money.

Any good tech can do this repair in your home in about 1 hour--I know as I have done hundreds of them.

If you need help or advice let me know--I am here to help people.

Blue convergence is off right will not adjust


Hi. there is a malfunction that has occurred within the convergence chip that is located on the PC board(demod). this is a Hybrid chip that controls the calibrations of the RGB streams. If this chip becomes unstable, it will not allow proper calibrations.

Replacing this failed chip will fix this issue.

The actual sony chip is not available at this time but, there is a compatible chip that will work with your set. i will post a link to the affected part below.
