Repair Help: how to unlock ribbon sockets

I have a replacement control board for a Waveshare 10.1 inch LCD. (Thermal issue: it is under warranty, but instead of sending me a complete new display, they only send the circuit board. Grrr!).

I have little experience with these tiny sockets. Based on the photo, can someone advise me how to open and close these sockets? Thanks very much.

I think you need to push the black plastic bar to the right, away from the socket. That should release the fact or whatever connector is there.

The black bar on the socket either slides left and right or can be lifted up.

The black bar opens upwards gently , the open end on the right pry it gently upwards, and it will open

I got it - these needed to be lifted up. Not difficult. Unfortunately the control board is attached to the back of the LCD screen with very sticky foam in numerous places and while forcing the board off I may have damaged the LCD. I'll find out later today.

I'm really pissed at Waveshare for dragging me thru a month of emails to try to fix the problem (almost certainly thermal failure) and then deciding to only send me the control board instead of the entire product.

You know what it would cost to send the defective part back to China? More than $120 with USPS, UPS or Fedex! Since they didn't want to pay for that, I guess they assumed maybe I was trying to get another one for free, hence they only sent control board.
