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.

Check resistors in the small PCB connected to picture tube. Check picture tube grid voltages. Check brightness control swing on the IC out put. Note down the IC no and search in the Google for pin configuration.
