On one the M100s I repaired earlier this year, it was not so much the zebra strips, but that they seemed to have shrunk. I had to apply thick tape inside of the metal LCD frame to increase the pressure on the strip. I think new zebra strips of the correct height would save quite a few M100s. I am interested in buying 4 of them.
I do not think it will help with missing horizontal lines. I am pretty sure that would be broken traces or lifted pins on an IC. I only have experience with the one that I repaired, so take that with a grain of salt. Scott M.

Steve, Thanks for sharing your experience. Depends on the display, I guess? New zebra strips were the answer for the display I have on hand — worked better than adding tape between the glass and bezel. —Jamie On Jul 6, 2021, 8:25 PM -0400, Stephen Adolph <[email protected]>, wrote: Jamie, Are the zebra strips a problem? I guess you are saying that for at least some LCDs with missing lines, a new zebra strip would help? For me it has usually been a pcb problem.

I’ve admired the M100 as a brilliant product for the past decade or so, and just picked up a really sad example that I’m trying to resuscitate. A couple of weeks ago I had a some fine-pitch prototype zebra strips made up to fit the M100 LCD (see pic). The first prototypes are about 0.3mm too tall. I’ll likely have another set of prototypes run with an adjusted height. I have two questions: Is there enough interest here on the list to justify an order of 1000 pieces or so? (Likely price is a few dollars each strip — more to come on price.) Do any of you have dead LCDs that you would be wiling to sacrifice to the testing gods? I would like to see ten or so LCDs improved by an upgrade to the new strips before placing a bigger order. —Jamie
