1983 Chexx questions

[hockey17]

Just bought 1983 Original Chexx table. Everything works except the score does not show up and the ICE letters are always lit up at all times. There is a green wire with yellow stripe not connected. Also U12 and U13 chips are missing if that means anything?

Anyone know the size of locks these use as they need replacing. Thanks for all the help.

Those chips are the sound chips so Im told.

I'm also looking for them. Not sure about the wires and the lights tho.
