Re: [M100] M100 / 102 Wanted
That's a shame. I'm sure in my 15-20 years here on the Club100 listserv the topic of screen repairs, backlighting, cleaning, etc. has been thoroughly discussed several times.But with all the amazing innovation happening for our treasured Model T format by extremely talented people, no options exist to rid the scourge of bad screens once and for all?

Re: [M100] M100 / 102 Wanted
Lloyd, I have successfully fixed vertical line issues with a Model 100, but I am not sure about a horizontal line. That could be a solder fracture on one of the controller ICs. For the vertical lines, my issue was a dirty zebra connector and not enough pressure on the metal LCD frame. I took the LCD apart and cleaned the zebra connector and then applied some thick tape to the inside of the metal frame and squished the entire assembly back together. It has been working well for several months now. It was a bit nerve racking because it will likely be worse when you first put it back together and you have to keep adjusting it until it is right. Then twist all the metal tabs careful not to damage any traces. Thankfully, I paid less than $80 for both of mine, but I expected to have to deal with some issues no matter what an eBay seller says.
