Blackout blinds won’t stay down

[Ashecnc]

We have a 2021 2670MK, all the sudden we have 3 blinds that will not stay down. We pull it down and it goes right back up. So strange it happened to 3, any suggestions on what’s happening? Thanks for the help!

I took one of the blinds down when it became loose. I saw a positive and a minus adjustment on each wheel but it was unclear what they adjusted. It could be a tension adjustment. To take them down you will need a #2 square drive screwdriver, on a long shaft to reach up to the screws.

Ours adjusted like those in this video. Just did in place in about 30 sec.
