Question about Sony KP-61S65 61" Rear Projection Television
Convergence problems are generally simple repairs, presuming you know how to solder and have a bit of brains about you. Eventually every projection set will have this problem - STKs are usually at fault (STK392-010/020/040, STK392-110/120/150/180, etc) and are easily aquired and replaced. Sometimes a fusible resistor is taken out in power supply circuit, sometimes a resistor will burn. Generally easy fix. Repalce STK and any fusible/blown resistor - you will need a multimeter, decent soldering equipment (NOT a 40watt iron or gun from Radio Shack, unless you're brave) and the replacement parts. But as everyone says - servicing TVs can be hazardous. Call a servicer if you're concerned, but in-shop repair should cost less than $250 - it would never exceed that at our location.

I just had my Pro 200 fixed with the same problem - needed 2-STK394160 and 2- FRX 25512RO and 1 - FRX25533RO This was to fix the digital convergence assembly, definately not a DIY job.

I purchased a RCA 61" HDTV 15 months ago at aprox $2000.00. Ofcourse RCA making such great products and backing those products !! Will not cover parts or labor except for the tube after 12 months? I have researched and discovered i have a convergence problem related to 3 or 4 (21 pin chips) part # STK392-110 , 112 ect.... can these be replaced fairly easy or are they hard wired ) soldered in. I need to know where these are located and with me and my wife electrical back ground can we fix these ourselves if we purchase the parts. I do not have a tech manual or scematics to help locate these chips? Can you tell were they are located or were the card is located that they are on? Thanks in advance for your help and site !!!

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Check the blue horizontal convergence amp on the convergence panel. Whether or not this is an in house solution, is up to your experience in electronic repair and specifically TVs. Good luck

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....
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.
