horizontal line only and sound working for panasonic tv

[amireh1]

Hi:

i have a panasonic tv and i dont know the model, but chassis no is TNPH0041 and CRT no: M68LGL061X .
The problem started with lines in top and bottom and when i hit the TV the picture become clear and good again.
i though it is a solder crack , so i started soldering some points on the board and this made things worse as the channels started to switch between tv and video.
then i started soldering again but finally there is a middle horizontal white line in the middle of the screen and the sound is working and sometimes the picture comes again but disappears quickly....what can i do and what is the model of this tv.

thanks

Any caps that are around the verticle ic would be a safe bet.
