Replace the entire DAC board (board with power suplly going into it) for easiest solution.

If the button on monitor is blinking, it means your computer is either turned off or in standby mode (or in hybernation).
You should push the power button on your computer to restore it from standby (or hybernation).

try checking the cables first.

Repaired! This sounde like a fuelty screen or screen inverter. To check this, connect to an external monitor, if the external works properly, then it's the screen or inverter. If the external doesn't work, let me know and we'll run the problem down to a more indepth (internal) trouble shoot.
