Hi,
In my service shop, I have a Panasonic TV model CT-27SL13G (mfg 07/03) with an odd symptom. The picture is about 6 inches high (black on top and bottom), but it is "warped" with a wavy edge (top & bottom).
I checked electroylitics in vert. circuit. Regulated B+ is 130V, there is +27V at pin 2 (VCC) of IC451 (AN5522). I scoped pin 2 looking for excessive ripple, but found around 2V P-P ripple. I "rang" the yoke with a yoke tester (ok) even though I didn't think it is the cause. I replaced IC451 (AN5522), but the problem remains. It may be a problem in the yoke return (I have no schematic)? Did you have a problem like this?
Thanks in advance, Brad
