Thanks, Cory. I? looked yesterday? but don't have? a tiny? enough tweezers to open the ribbon cables! I will get some and try re-seating them later.
By the way, I? ran across this some time ago but? it got lost in the shuffle, and maybe someone else has? posted this video from a knowledgeable Russian, but may not have noticed? that you can translate into English:
Subtitles are in Russian, but you can set the gearwheel options to auto-translate into English subtitles.
