BTW, are you sure a new display is needed for this M100?
I sure hope not. From what I've read so far, reinstalling it would be a
royal pain. . .
Firstly my M100
TechRef lists separate part numbers for the display itself, the mounting
frame, the driver chips, etc. So you might be able to reapir the old one.
And secondly, I've never had a M100 display fail. What normally fails is
the -5V power supply (normally an O/C rectifier IIRC). This supply is used
by the serial port, internal modem _and_ as the bias supply for the LCD
panel.
Any idea which rectifier it could be (I see at least 22 of them on the
motherboard)
I guess I could check them all with a voltmeter, although in-circuit
testing of these things is fraught with peril. . .
