That usually means that the polished silicon plates no longer make good contact with the LCD glass. It is rare you can fix this yourself. But you can remove the LCD by removing any small covers or rubber feet from screen side of the lid.Power off machine before going further. From there remove all the screws and remove them. Just remove the screen gently and look behind it and you will see printed barcodes with numbers. One of them is a part number. Ebay that number and find out how much you can get one for. Be sure the sell has a good rep and a return policy. Order one in and replace it yourself. Or take the parts you have and a repair shop may not charge much to replace the screen you have.
email me if you need any more assistance or reassembly.

Unfortunately the fix is a new lcd. The tab welds at the top of the lcd are not allowing that portion to work correctly. As these tabs are fused to the lcd you will need to replace the lcd. My Toshiba M105 is almost the same.(I Have 4" Gone) on the right side. so to use it I clicked and dragged my system tray from the bottom to the side. And shrunk my web pages to utilize tthe good portion.
I suppose I should replace it but being only 18months old the LCD's run about 160.00 USD.(sometimes I just hook up an external monitor.

This is for the original problem.. Not the second post.
It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.
This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.

Some components in the vertical deflection amp have been going out of spec with age.
The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.
I would be considering a new set.

Those lines are beaming in from the planet Alenod. For the moment you'll only be annoyed by those lines. But when those lines finally expand the entire surface of your screen you and everything in your viewing area will vaporize. Gosh, If I were you I'd chunk it as quickly as possible and buy a 47" Vizio! They're on sell at Sams! Pleeze hurry!!
