I have a DMD of which the power connector solder is loose. In the sense that when you hold the connector down, the display works.

But the problem is: how do I temporary remove the electronics board from the glass, so I can resolder the connector (it's on the underside of the electronic board, between glass and board)?

I suspect the red top has something to do, in securing the glass on that side?
Do I pull it or turn it or what?
The other sides are linked to the glass pins ribbons.

Anyone an idea?

Thanks

Thanks for the info, always wondered what that red cap was for
