I had one of my machines LCD die and I bought another with a dead mb for $25 and ended up with a lot of spare memory as well as a LCD. Good Luck James

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.

Needless to say they were right. Often, alignment is easy _if_ you can figure out what has to be aligned. In the case of the Sharp I mentioned earlier, the display had to be fitted into the frame hard against one side (I forget which). Sometimes there are alignemnt holes in the PCB and in a tab on the frame. Sometimes the whole thing was clamped up in a jig at the factory, in which case you've got problems. BTW, are you sure a new display is needed for this M100? 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. [...] -tony

Out of curiousity, what is the symptoms of a "badly misaligned" display? I have an M100 which is showing nothing but a couple of big bars and some random video noise. From typing blind I can tell it is not a CPU problem. Part of the reason I ask is that this particular system may have taken a bang or two, though there is no obvious damage. <<<John>>

OOoooh, you scared us! :) Did you used those stupid "renewal" kind? This Renewal and even rechargeables does not give oomph as well. Some really prefer very strong batteries like Energizer, Duracell and compareable quality $1 stuff. It takes a while to find cheap ones that does equally as good ones. I did find specific brand that does pretty good. Racvac, it have no punch at all bec it's carbon based technology and it's good for some other things. Did this M100 needs 4 AA cells? That gives about exactly 6v for that 5v regulator and LCD stuff to work if cells drops past about 1.1-1.2v the usually LCD fades out then crashes the machine because it's 4 cell design. If Tandy designed 5 or 6 cells for M100 years ago, it will run past 1v per cell and extends the running time! Fresh batteries are just about over 1.5volts each. Similar topic on voltage changes: my hearing aids uses those 1.5v 765 type. When that cell start to die, I start to hear distorted sound and general fading (twirls the bitty tiny volume knob) when voltage drops past 1.2v or so then dying to silence. <DART!> Don't have the cell with me when outwhere nearest any suitable resellers. If someone wonders, typical hearing aids sometimes helps hearing impaired but in my case, I'm profound deaf. I can only hear sounds and understand genernally different sounds (screaming, banging, engine purring and backfiring, baby crying, train tooting and such.) But not able to understand normal frenquencies like talking. But I assure all that I can hear the world around me going on. On this side, I saw one worst battery kind when I put 'em into flashlight, it lits up brightly, immiately fades out. (!). They're were new!
