ok.
I've gone through the manual and have established that the lights in question are GIs, I had a bit of a fiddle with all the wires on the CPU board to make sure they are well connected and havent managed to change anything. Looking at the manual I can work out where the connection is for these lights, and just by going off the colours of the wires i'm still stumped - is there any simple way to locate the problem or should i just get a real pintech to come and have a look?
cheers.
