I blew up the backlight regulator on a GTA02 A5 here by hotplugging the
LCM connector... the flat cable has a 2 layer set of terminating pads on
it and it trashed the LED regulator on the PMU. But if you didn't even
open the case I dunno what makes the problem, I never saw the regulator
have trouble without me causing it. The LCD flex cable is held in place
by some sticky EMI tape so I doubt it moved.
NOR flash code should definitely start the LED regulator up without any
question.
