Same Problem
Mar 28, 2008
-   I have practically the same problem. I have a different TV, a Toshiba 42hdx82 and the problem is with the red, not the blue. I can adjust everything to line up fine, except for adjusting the red right and left. it' won't move, and the picture is almost an inch off. Looking for some kind of DIY solution.-   Atropos

-   I have a blue glow appearing at the bottom of my 62inch rear projection TV. Am not sure what causes this or how to get this repaired. Any suggestions for repairs would be welcomed.-   Kushilla

-   My projection tv has all the sudden acquired blue double shadow-ghosts. When I run the picture perfect, all colors align except the blue. Please help on what parts I may need to replace. Have only tried adjusting the color through the menu picture settings with no luck.
Thanks.

-   I have replaced my convergance board and now blue will not focus using the perfect focus feature. what should i do next. I'm an electrician and can troubleshoot using a multi-meter.
Everywhere here in gainesville is rtying to charge me 400 dollars I call them with the exact problem above and they all say it could be a multitude of prolems and on a TV that size i'm looking at a minimum of $375
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.
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 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 !!!

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 have a sony 51" rear projection. after a period of time the screen will get green wavy lines through it until it is unwatchable - then it needs to rest to work again
my set was only 3 years old when this problem developed, my blue has shifted to the left severly and canot be adjusted. if you look to the upper right of the screen it actually looks bowed in to the left(blue)
TV was purchased in 1996 Hitachi Ultravision picture is getting darker and has blue shadow. I had the same problem a few years ago and payed for a repairman to come to my house for service. He told me to occasionally push the magic color button but this does not fix the problem. HELP!
I am having the same problem the blue convergence lines will not move up or down just side to side. but everything else matches up fine I have great picture quality except for the color being yellow greenish tint is that normal since that blue is not mixing so im only getting 2 colors instead of RGB? Im a digital artist not a tv repair man thanks

Hello, I have the same problem as described. I replaced the STK392-110's with STK392-180's, because I read that the chips are most likely the problem. Unfortunately, it still has the same problem. I am currently working on a degree in Electronics Technology, and have minimal experience troubleshooting circuit boards. Does anyone have any idea what I need to check next?
