It sounds like you have lost the vertical sweep circuits, it can be the Vertical out put IC is bad, Vertical yoke winding is bad, caps is bad. You will have to open it up, but you must be real careful since the picture tube can hold high voltage (24~30,000 Volts) for a long time after the monitor is unplugged, you will need to discharge the picture tube first before working on it. You may want to leave this to the pro.

Tap the top of the TV and if the picture comes on in full screen then it is possible that there are DRY SOLDERING points on the board.
use a good iron to touch up the soldering on the vertical and horizontal sections, the driver IC's. get help if you are not able to do the job but it seems a minor job.
