Question about Panasonic PT-47WX42 47" Rear Projection Television
If the CRT Projection television has several colors or one that arent lining up, if due to an impact - you may have a broken mirror, if just happened all by itsself it may be a convergence issue, either issue is repairable, probably for around $400-$500. I dont recommend taking a set like that into the shop as sometimes transport can break/crack a mirror or throw convergence off.

SOURCE: Convergence Problem?
The convergence IC most likly shorted, and burnt out the b+ feed resistor. There are two IC's inside this set to control the green red and blue convergence. They are most likly STK 392-###. The ### is another set of numbers that change depending on the model of the set. They each have three amps inside each one. You really should have both of the IC's replace with only original parts, as sub parts do not hold up and will not last as long as they should. Both IC's are soldered into place and if you decide to do this yourself, please be aware of the extemly high voltage inside of these puppys. there really are no user replaceable parts inside these sets unless you have solid state repair experience. Not only will yopu need the proper IC's, but you will have to find out what was burning. my best advice, Play it safe and call in a trained tech to assist you with this repair. The price should run someware between 300 to 450.00 to repair. Good Luck Please do not forget to rate this thread.

You will need to replace your two convergence I.C.s.They are two large
IC mounted on a large aluminum heat sink.Replace both,look for any
burned resistors near them,replace those if needed,and readjust your
convergence. Good Luck
Let me know if you need any further help

Had same problem with Red. Could not adjust. Funny broken lines. Found this link:
Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.
Problem solved. TV works great.
I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.
