I have the same problem here with an Silent Scope and have been told that when the timekeeper Ic dies you need to replace it and it needs to be programed for the game to work.
The only one that could do that close to me was Electrocoin in the UK...so i send it to them and it took 6 months to get it back !
I also have an Racing Jam board with the same error "hardware error 7" and it needs the same treatment as Silent Scope....
So if anyone one have an better solution it will be great !
