So I woke up this morning and the Atlas touchscreen display in my bedroom was dark. A check with my voltmeter told me the AC power supply cube was dead.
Hey, no problem, i have THREE other working ones I saved from my Atlas displays which previously had frozen up. I take one of them plug it into my current display and it powers right up. "YES" I say until a few seconds later I realized that now THIS display was frozen at the start-up screen.
Now I don't know whether there was a problem in the old power supply which caused the display to freeze, or whether something in the display killed the power supply.
Owning an Atlas is a never ending adventure.
