After putting a load of games on the Shadow over the weekend the 4 bank drops at the back of the Battlefield have stopped resetting after they've been knocked down. When I first turn the machine on they are reset but then you can hear the mech trying to push them up another 3 or 4 times like it doesn't realise they're up already. During gameplay, when you knock them down, they don't reset like it doesn't realise they're down.
This made me think dodgy opto so I had a quick look underneath tonight to see if there was anything obvious. In switch test, 3 of them register but opto 3 doesn't when i use a bit of card to trigger them. I also noticed that jiggling the wires going into the connector on the opto board seemed to trigger some switches as well. Does this sound like a knackered opto or a dodgy connector (or both)? It was working fine on Friday and during Saturday but started playing up yesterday evening (don't know if this helps identify what the cause of the problem could be).
I'll try the camera test tomorrow on the optos to see if that shows anything as well.
