Good news and bad:
Good news: I also did the twenty questions/twenty photos dance with FW support, and they said they are replacing the screen.
Bad news: In my case at least, it looks like an assembly error led to the screen killing itself, possibly by twisting/bending the eDP cable. Support conspicuously declined to address my questions about this.
I say “assembly error” and not “bad luck” because in my case, there are two different adhesive patches on the eDP and antenna bundle wiring bundles, that look like they are supposed to hold the cable bundles in place and keep them from twisting around the hinges. I checked my Framework Chromebook and both cable bundles are secured in place with the adhesive. On my AMD 13", both adhesive patches still had the cover/mask in place. The eDP cable had a small bit of the white heavy paper with a waxy side, and the antenna bundle cable had a small blue piece of plastic over the adhesive. I don’t work in the OEM factory, but that sure sounds like a missed assembly step to me, and while I’m not an expert, it certainly seems plausible that it led to the failure.
Anyone else with a failed screen see anything similar? We might all have gotten one-off “bad luck” issues, there are a lot of Framework machines out there, but I’m curious to know if the same errors have showed up more than once. I’ll see if I can get my photos somewhere that I can link them here.
