Anyone understand JPM Impact Multiplexer!?

Morning all
I have a problem with Crystal Thriller machine (JPM Impact).
The 7 trail lights are not working. Everything else is fine. Looking at the manual, these are 198..204. But, 192..196 are fine, as are 205..207 (both of which are on the same SI of 12 and have he same grey/red wire looped to them.
I'm a bit stumped!
Initially I had planned to replace all the output transistors too, but looking at the board I can't get my head around how the output mux is working. There are 16x TIPL790's, 15A jobs, and 16x TIPP116s, weedy little things; surely in a 16x16 arrangement both will be subject to the same load?
What am I missing!
Many thanks for any help.
