TV will power on and has sound but one side of screen has horizontal lines.

There is a difference between the two pictures. I would say clean the ribbon cable from main to tcon and the 2 ribbon cables from tcon to the LCD. See what that gives.

Thanks for the reply. I tried cleaning all the connections on the T-Con board going both ways. Still got the same result. Horizontal lines appear with what looks like the lines are not infrequent in their appearance but are not permanently visible. I was thinking of replacing the T-Con.

Had a similar problem on a 46" AWA which i bought replacement tcon and thought that's fixed OK but a few days later split picture with bad half background green colour back. Got rid of that again by very careful fitting tcon screen lead on problem side but as soon as set moved to another location fault returned. The real problem was the ribbon from tcon to screen fitting at the screen end which was in frame. Fiddling finally too much for the ribbon. The set had been out in the weather previously so in the end I scrapped it.

That's where I'd be looking next too and the tab bonds.
