Have similar problem on a Panasonic Tau model CT-27SL15.
It's a 27" CRT TV manufactured around 2005.

Other posts / solutions on this problem say possibly a capacitor going bad in the vertical circuitry / near the vertical IC / vertical blanking circuitry. Telephone call to a TV repair person mentioned something similar - "possibly a bad capacitor in the vertical circuitry".
Found a service manual online w/schematics and board layouts.

See pg 25 (of 42) - Deflection Schematic Diagram (Main PCB)
Shows: V Output IC - IC401
Finding the actual bad component(s) may not be so easy.
Anyway ... just wanted to add this comment.

Push the power button and the action button on the tv set until it shuts itself off and this will reset your tv. You cannot use the remote to reset...must use the actual tv buttons on the television set.

plz check fuse then check power suplay or h.output transister

Are you using the TV/VCR button on the _original_ panasonic remote control? And do you mean it does nothing?
