Disconnect the coaxial cable connector, cable to the mainboard, and inter-board sub-screen cable on the daughterboard.

⚠️ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).

Remove the sub-board. It may be glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.

The sub-board, also, may be attached with attachments like latches or hooks, be careful.
