I picked up a Samsung SyncMaster 930b at a GoodWill near my home, it seemed in great condition when I picked it up, plugged it in at the store, turned right on, Digital popped up in the corner, I thought everything was fine. Got home, hooked it up to my laptop through a DVI-HDMI cable, the desktop popped up, for about a second, then the screen went black. Now I can only get anything to display when I press the button to switch between Analog and Digital, it will pop up for a second when it switches to digital but then it shuts off again. I even tried it on an raspberry pi I have and the same thing happened. Unfortunately though I dont have a VGA cable to see if maybe its just the DVI connection. Any advice from anyone or has anyone experienced this before and is it fixable?
