Ugh, I seem to have problems at every stage :(
So I have gotten to the Fluxtest and have issues on both boards.
On the LH board, no red led on SW14. Have tested the LED with multimeter and it's fine.
On the RH board, no green or blue on SW7 and SW15, same as above, LEDs are OK.
I've tried the usual, looking for obvious faults, diodes are all correct., soldering all looks OK. Any hints on where to look?
