Anyone would know which is the Convergence IC (integrated circuit) on a Panasonic PT-47WX49?
I have a convergence problem, and I have try in vain to adjust the setting in Service Mode, so I thought to replace the convergence integrated circuit. Is this a common problem?
Any help will be much appreaciate.

Hi, Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded. On circuit board, IC location number is IC7001 and IC7002 Let me know if you have additional question. Thanks.
The convergence amplifier is a three channel Integrated circuit which controls the convergence alignment of the three picture tubes in a rear projection TV. Your convergence amps are STK392-110 there are two of them also check the six 2.2 ohm 2watt resistors
I would look for burnt resistors off the red IC, hopefully its not the DCU (digital convergence module) as most of these are integrated into the signal board. here is a tutorial i made up: http://www.fixya.com/support/r5001731-convergence_diagnosing_convergence Let me know if I can be of further assistance.
Yes it is that set uses the same IC STK392-110 You can get the new ICs at this link and they will provide free installation instructions with pictures as well as free on line tech support instant messaging while you do the repair. heres the link. http://servicemanuals.vstore.ca/
The two convergence IC's are generic part# STK392-110 and Panasonic part# C5AA00000203. Also check for burnt or discolored resistors nearby. Since this is such an easy repair,a schematic is not necessary....The hardest part is identifying the burnt resistors and aligning the green convergence in the service menu.
