I have try to clean tips of ribbon cable...i did it with brass brush.... and as u see all tips got oxidation and they are black.....I think they don't let contact true...

Look like unused traces but could be wrong...just that oxidation rarely would terminate on selected few and so precisely on each...

Those ‘extra tracks’ are clearly for options that the OP’s unit never had.
