my treadmill console lights up but the switches dont respond?

my treadmill console lights up but the switches dont respond. It is as if they are all stuck, I mean it is not flexible anymore? I opened the console and a capacitor/transistor like part was lying on the inside apparently broken off from the circuit board and the nomenclature corresponding to that part said R40. The other part which looks quite similar says R 39.
Please help:
