HELP Wiring BT block terminal 77a

Good morning, I've disturbed the terminal block (terminal 77a )whilst changing my window yesterday...Can't seem to get back connected 😕 If I could get some clarity it would be much appreciated.

You just mirror the wiring top & bottom so the same colour wires are connected to the same pins on the connectors. If one has come adrift & you don't have a punchdown tool, an old credit card can be used to push the wire back into place.

See picture.

If this doesn't work then the possibilities are that the colour code hasn't been adhered to or the wiring is damaged.
