Is this your game and it started doing this, or is it a customer's game
and you have not seen it working properly and have no idea what screwups
the owner or previous tech may have done. This info is useful...

It sounds like someone miswired a connection.

Let me see if I have it right:

1) Centre Hole Switch shows correctly in Switch matrix Test

2) Centre Solenoid fires Upper Left Solenoid in Solenoid Test.

3) The Upper Left fires when it should be Centre.

What happens with Upper Left Solenoid when tested - does it work correctly?

Is the 6821 that controls the coils in a socket? If so, I would swap it out first. Then the 74154 that multiplexes the signal, and finally the u45 or u50 that passes the signal to the transistor.
