All-
I hadn't used my M100 in probably a month or two but the recent null modem
discussion inspired me to fire it up. When I power on, all I have is a blank
screen. I can adjust the contrast but there's nothing else.
I've followed the steps at

including the various resets, except I don't have a wall charger so I left it
off overnight with the memory power switch on, with four brand new AAs. Then I
took the batteries out and turned memory power off and left it alone for
probably an hour.
I think the key is somewhere with memory power. If the mem power switch is off
and I turn power on, it's completely dead. I can't even adjust the contrast.
But as long as the mem power switch is on, I can turn the power on and darken
the lcd with the contrast knob. Also of note, as long as mem power is on, when
I turn the power switch off the red low battery LED blinks rapidly once - which
I think is normal, at least my M100 has always done that. If mem power is
turned off and I switch off the power, the LED does nothing.
Anything else I can try? Do I need a new backup battery? To my knowledge the
one that is in there is the original. This is a relatively recent LCD that I
installed myself five or six years ago, and I did open the case just to verify
all those connections are good. And anyhow I can darken every pixel with the
contrast knob so I'm tempted to rule that out anyhow.
