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.
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.
