Lee, Any ideas on what else I should check?
I just checked the two photos with the old and new light board, I have connected the wires correctly. Any wires that are the same color were numbered so the correct order was used when installing the new board.
Old Board:
New Board:
Which wires should I try swapping or is there something else I can do to troubleshoot this?
Cannot really tell Derek as the wire colors are no give away to where they go.
Trace each wire to its origin and confirm.
PAD 1 goes to right channel output.
PAD 2 goes to the attenuator switch blue wire (this looks correct in your photo)
PAD 3 goes to attenuator switch ground, the crossbar orange wire between switch poles. (this looks correct in your photo)
PAD 4 goes to the ground bus bar between the 2 big capacitors.
PAD 5 goes to the attenuator switch yellow wire (this looks correct in your photo)
PAD 16 goes to left channel output.
PAD 14 goes to the AC transformer low voltage secondary
PAD 15 goes to the AC transformer low voltage secondary
Thus the wires you need to trace back are PAD1, PAD4, PAD16, PAD14, PAD15
Derek, I got my pic out of the wire connections and it looks to be correct. Just verify with the multiMeter that the white wires you have going to pads 1, 4 and 15 are going to the right place. I only use white wire for grounds so it's easy to trace. The Attenuator switch is a BIG PROBLEM and they are impossible to clean or find new ones.
Pad 15 you have a white wire on and it should be one of your AC lines (14 and 15)
pad 4 you have a white wire on and it should be ground from the ground bar on the caps or star ground.
Pad 1 you have another white wire on and is your right channel input (pad 16 is left channel input)
It appears your attenuator is correct connection wise, (but may be dirty inside) does it always act FU or can you mess with the attenuator knob and get the meter to work corretly???

Check DC offset where wires go the input of the DC protect board.. Speaker wires. Each channel..
