Man! That was the longest 48 hours I've ever experienced. But W0LED-10 is back on the air.
After tearing down the laptop to the display level there appears to be an intermittent wire break in the motherboard to display cable. It's right at the point where maximum stress occurs every time the display is opened or closed. I think it's probably a wire leading to the inverter because when the screen goes blank it's dead black. So the bits and pieces of that laptop are secured for the time when I can get back to the repair.
