Question about Computers & Internet
Probable source of the problem is the horizontal output (and high voltage) circuit although it can be killing the video earlier than that too.
First step would be to dis- and reconnect the video cable to ensure it isn't a simple contact problem.
Second, using the brightness and contrast controls to see if anything is still visible. If you have a single horizontal line across the screen, then the problem is in the vertical deflection circuit instead.
If you have nothing, turn the monitor off, wait a few seconds and then back on. If you get a picture first then only a dot, its back to the horizontal circuit again. Try to note how it dies.
You may be able to somewhat diagnose the problem this way but that is a long way from a repair and with the cost of labor and possible unavailability of some parts, you should get an estimate before repairing it since it is possible that replacing it is cheaper. This is not really a DIY project unless you have technical background and a couple of test instruments.
