Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television
The convergence amps have most likely failed. Your set takes two STK392-110 Sanyo built Ics, Pansonic p/n# C5aa00000203.
They're located at board positions Ic7001 and Ic7002 respectively. In addition, you will need to test all the low ohm yoke return resistors in that circuit for change in value and replace any that don't meter correctly.
In the shop this is a relitively modest job with the most of the cost going to labor. I suggest, if you're going to have a shop do it call around and ask what they charge for changing the convergence amps and take the unit to them to save the pickup and delivery charges.
