Then it's the logic board that needs changing.

I've got a 28" Hanns-G monitor that works fine for 5 minutes, then shows a bright band for the bottom two thirds of the screen. It does it using HDMI or VGA and I have tried different HDMI and VGA cables. I tried it on 3 different computers. It is always the same. I don't think it is the power board, the capacitors or the inverter/backlight bulbs. Any ideas? TIA
