Monitor flashes on, clear, crisp, beautiful, then 2 seconds later goes black and will only come back on if i unplug it and plug it back in, but again only for a couple of seconds. the green light indicating the monitor is connected stays on at all times.
The green light only lets you know there is a valid video signal reaching the monitor. If the green light was not "on" your problems would possibly be within the pc itself. Something is not holding the circuit for the backlight "on" thus going black. Suggestions are:
1. Take it to get it repaired (if not under warranty) Hyundai carries a 3 yr warranty on this monitor. Website provided.
2. Buy a new monitor
