X230 WQHD adapter card repair

[la-luva]

The card was working perfectly, until i decided to use it to test an fhd lcd LQ133M1JX36 with a 30 to 40 pin adapter.
After that it will not output video anymore.
Motherboard seems to be ok, displayport, vga and both videoutputs on dockingport are fine.
Fuses i have found on motherboard on both sides are OK.
I now think that it is the wqhd adaptercard that is broken.

What are my chanses to repair adapter card while still attached to motherboard?

Has anybody succsessfully removed adapter card without damaged motherboard? I have a spare.

Last resort is opening lvds port by flashing bios back to original again and hope that output is still alive.

Edit:
I am not completely sure that it is the adaptercard that broke something, it may have been my stupidity not thinking that the lcd cable from the adapter card to lcd is taped with adhesive tape that is conductive, and may have shorted something laying on top of the adapter card.
