So my uncle gave me his 22 inch monitor he hasn't used it for 4 years now so i connect it using vga cable to my pc, and turn the pc on, the monitor was on when the computer first started after that it turned of and had black screen but the light was on so i turn it of and turn it back on, it showed up the screen for 1 second then turned off again but the light was still on.
Any suggestions?

Thanks you!
