MasterChief - The tube could be worn out or faulty, the HT circuit could be failing to produce enough potential to pull the electrons onto the screen, the 'heater' may be defective or a number of circuits could be at fault. In other words it's either the tube or the electronics.
Since about the only things in a monitor are the tube and the electronics then you might as well replace the whole thing. Fixing CRTs is a 'black art' and requires a different skillset to digital systems. Not something you can pick up by experiment imho.
