You can either have a bad Y-Upper buffer board, or dirty contacts on the plug associated with the horizontal line. Best to have a service company look at it.

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

I had the same problem to and I fixed it.
At the bottom of the plasma there are six or seven ribbon cabbles that come out of the panel and connect to like driver boards. Each ribbon drives that section of the panel. Mine had it down the centre so I unplugged that ribbon cable and on the underside of a metal plate attached to it there are four big resistors and four small ones. The big ones labelled 100 required resoldering. Once they were resoldered it worked just fine.

not necessarily, sometimes the connectors that feed the screen get old and dirty
If you have some electronic skills, open the TV and clean the connectors around where you see the symptoms and you may have a good chance to get if fix by doing that...

Maybe is a lose contact in the conectors of the screen.
You need disconect the conectors, clean with isopropilic alcohol, and reconect the conectors.
