My screen is showing double vision with the second picture in red. What should I do?


This is called a convergence problem and you have 2 choices: get a estimate from a shop (250 is typical) or if you are handy do it yourself; I have available start to finish, step by step instructions for this repair in the set you have. They tell you everything you will need and exactly how to do the repair. SD TECH

I am having a convergence issue with my Panasonic Rear Projection Television. Is this something I can repair myself? If I did hire someone to fix this for me, about how much would this cost?


I am the right person to talk to.

If convergence problem total parts cost on EBAY would be under 25 dollars AND I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THE DO IT YOURSELF PERSON TO DO THIS REPAIR.

THE instructions tell everything you will need and the best way to get at the two STK-392-110 CHIPS THAT NEED TO BE REPLACED.

Repair involves getting at and replacing both chips, it does involve being able to solder--not hard on this set.

If you want the instructions here or provide a email I will if you rate this solution very helpful give them to you for free, they are based on my actual experience doing hundreds of these sets with this problem.

See attached photos of what the chips look like and what a typical convergence problem looks like.

Green convergence on Panasonic PT-53WX42 is not ligning up...


Does not sound like the chips are bad.
What you need to adjust is "SKEW". You need to enter "service Mode" then go into "Coarse Convergence". Skew can be adjusted for all 3 colors. Unless you have the service manual, these corrections should not be attempted.

To clean the INSIDE of the screen, you really have to disassemble the TV. Remove all the screws that hold the "back" ( the piece with the mirror) to the front (screen) assembly.
The screen can be cleaned with a solution of diluted isopropyl alcohol, no more than a 50% solution. Drugstores will carry it, but it might be 70%-90%. Just dilute with distilled water (not tap water as it contains minerals). Personally I have used 70% with no ill side effects but 50% is recommended.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Green horizontal deflection


Change both STK convergence IC's for reliability. They amplify/control both horiz and vertical. re-align after replacement.Locate them on the largest heat sink in your set!
