Re: black screen

How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.

My monitor showes for a split second then goes black

First, can you attach another monitor to the computer to check to see if it works?

If it does, then your monitor is going bad. Possibly the power supply.
If a second monitor acts the same way, then it's your video card.

Screen goes black, but power light is on (not blinking)

The problem is not with your screen. Its the problem of Video Card of your system which is unable to send Video Signals to the Screen.

Monitor keep going to black screen while viewing.

Disable the Screen Saver in the Display Properties from Control Panel of your Computer.

A Black ScreenSaver is active in your Display Settings. Change it to "NONE" and your problem will be solved.

Power Failure

If you mean the Monitor is powered by an external power supply Then that indeed is an option worth trying Simply get a multiple voltage one and set it to the voltage of the existing one. There may be internal problems such as the inverter But this will be a repair shop job.
