Beogram 7000 fault?

Hi. My Beogram 7000 has decided that sometimes it will not lower the tonearm when it should, sometimes it will not raise it at the end of the disc and always it is now not controllable via remote at all, or via the turn (()) control on the deck.

All this after the unit was stored for about 18 months previously, all was good.

I am assuming that a control module has failed somewhere but perhaps someone else has experienced such a thing with a BG7000 previously? 

Maybe just a good clean?
