Jason,

*If* the M100 display is similar to the Tandy 200 display, they are _not
screwed together._ They are held together by a cheap pot-metal bracket with
nothing but tabs pushed thru slots on the LCD controller PCB and then
twisted. You will get 1, maybe two twists on each before they break. These
tabs must be *firmly* twisted to gain enough pressure on the LCD for the
pressure sensitive glass contacts to work.
I had a badly misaligned T200 display that I attempted to realign...
realignment is not as easy as it would seem, and yet on my 3rd attempt it
was *perfectly* aligned. I had all of the tabs twisted back with decent
pressure and it was still holding... then, alas, the *last* tab broke, and
it was close to a corner, easily wiping out 10-15% of the display. It was
already a lost cause so there was nothing to lose, but I speak from
experience -- it's tough to bring these LCD's back from the dead.
