Question about Panasonic PT-53WX52 53" Rear Projection Television
I have gone through the standard convergence alignment procedures offered in the menu of the TV. It does not seem to fix the red and blue convergence in one small area of the sceen. The middle of the screen on the far left is way out and it is very noticable when there is writing or lettering on the screen. I had a tech out 2-3 years ago to fix the same problem, and he did. When he did, he simply used the remote to get the TV into a "service mode" with a much more specific adjustment pattern( more than the 9 point offered in the menu). Can I access this mode myself? It looked very easy I just don't have the book/manual that told the tech how to do it. Can I buy that manual? having the same problem wondered if you could help me get into service manual using my remote. much thanks
I actually disagree with that information. IF you can move both horizontally and vertically the blue and red convergence then the ic's are fine.

I think your convergance amp ic are bad.
The STKs are common and if you have an experienced electronics tech around they can replace them for much less money but the tech must have advanced soldering and IC exchange experience.
The STK ics, two of them, can be purchased on line for around $20 to $40 each.
Partstore has two models available - one for around $40 and another for around $55.
The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.
It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.
Don not run the tv till you have it fix you will cause more damage!

Tips for a great answer:
Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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 yourconvergence 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.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed.
