I have a Panasonic 47WX53 47" (4 years old) that all of the sudden developed a shift in the Red projection to the left and a slight curve to the left at the bottom. Tried to use the convergence menu to correct, but doesn't shift far enough to correct. I called the local service shop and they gave an estimate of between $300 and $500 to fix. I have messed with electronics for years and for that kind of $$, I will try to fix it myself.
I've read a couple of other posts with a simular problem that have suggested to replace the "Convergence Box". I've looked inside the unit, but don't see a "Box". I do, however, see the two convergence IC chips. Is this what they are refering too? I looked the part# up on MCM Electronics and it costs about $20. Might be an adventure to change if thats the problem.
If anyone has a solution to this problem, or has had the same problem, please post a reply.
I have a blue shadow and too much yellow on the right side of the screen. I've tried to use the manual convergence adjustments in the setup screen but the blue won't line up properly on #'s 2, 3, 6, 8, and 9. The blue cross won't go far enough to the right, especially on #'s 3 , 6, and 9. I've taken the back panel off the TV but am not sure where the convergence IC's are. Does anyone have some kind of a step by step instructions on how to replace the IC's? I've never done this type of work but am pretty handy, besides I can't really afford to pay a repair service.

Re: Red shift to left with curve at bottom
Par 2 = " I do see the convergence chips..."
Par 3 = " I'm not sure where the IC's are...."
Please verify STK part # of IC's on large heatsinks.....
And then I'll give you step-by-step instructions......T.

For this problem, what you have to do is here I found this solution: Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labeled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. That should do the trick, Hope this is helpful. Please dont forget your rating.
It sounds like you need the convergence amplifiers replaced. Are you an expert solderer? If not, I would have a qualified technician repair this. Most places here in Alabama will fix it between $200-$300.
Yes you do need to change the convergence IC's. But you really should buy the replacement IC's that the manufacturers recomend as these IC's at MCM are cheap replacements and sometimes they simply do not hold up to the factory specs. Go to http://www.partstore.com, enter your model number and you should be able to find the proper IC's there. If you notice the price is a bit higher, thats because they are the right parts!. Next go to MCM electronics and get a tube of heat sink compound and apply a generous layer on the back of the new IC's before you install the new IC's. Also you should check around for overheated or cooked resistors around the area of the convergence IC's. Now when all is sais and done, you will be better off to go ahead and get the service manual so you can do some convergence alighnments. The manual is good to have as it tells you how to get into the service menu and what to adjust and for what. One word of warning though, in the service menu, DO NOT make any adjustments you do not know anything about AND before making any adjustments in the service menu, write down the values so in case something messes up you have a place to go back to. Good Luck.
