Darned if I know :). It is another type of reset for the machine but I
haven't taken the time to read the manual to find out what it actually does.
Another thing I did when troubleshooting several of them was to pull out the
RAM chips (power off of course) and then power it up again. Turned out one
of the machines had a bad RAM chip and that prevented it from booting up.
There are four RAM sockets and the first one was always soldered in with the
machines I looked at. The rest were socketed.
have one model
100 that has no display when I turn it on, but after
waiting
a few minutes, the display begins to show.
I haven't tried that. How long does that take? I am assuming
you have tried
both types of reset: 1) the reset button on the back, and 2) holding
shift/pause while turning the machine on.
I tried the reset button, I didn't know anything about shift/pause. What
does that do? Does the
display show anything
when the contrast knob is turned?
The contrast knob doesn't do anything . . .
