Rob - please test the lower PF illumination in the GI test menu.
According to John (Who knows his shit backwards BTW) - this is the slings etc plus 10 other GI lamps on the lower half of the PF.
Same circuit should also give you the globes next to the raft in the backbox. (Is this the backbox string that is not working?)
You really need to find out if this whole "yellow" GI string is dead - or just parts of it?
Assuming it's the whole lot (it sounds like it from here).
Do the continuity checks that John outlined. Remove all the connectors from the driver board before you test.
i.e. * J115 pin 6 to fuse F108 (upper left) to J120/J121 pin 9.
So - Pin J115-6 should be a circuit with Fuse108 and ALSO Pin 120/121-9
Test all 13 points listed.
Post back what you get. (Or don't get?)
