Advent C1 Monza Speaker Problem

[TurtleTom100]

Hi all

I have replaced my advwnt monza c1 laptop screen as it was damaged put it back together and realised that only the right speaker was working.

Not understanding why I purchased replacement speakers (incase I had trapped a cable) but these are exactly the same just all out the right speaker.

I have looked again and it appears that it is only this connection direct to board so I don't see what else it could be.

It isn't the balance on the laptop as I have tried with no right but 100% left and it is dead.

Any ideas would be appreciated I have had a Google but can't find much it appears the c1 either doesn't break often or was a limited amount made.

Either pin is bad or speaker died. Maybe something fall in the magnetic gap. Also, the ribbon cable can be badly stuck in the motherboard.
