In the lamp test, I see that the *THING* lamps only light up when other lamps light up. For example when Lamp 72 (Right Special) lights up also Lamp 82 (Thing T) lights up, but there is no light when Lamp 82 (Thing T) should light up.
According to the diagram Right Special belongs to column 7 at J137-7 but there is nothing connected to J137 on my machine.
Thing T belongs to J138-9 but there is some bad soldered cable in there which I tried to follow but cannot find where it connects to.
The Yellow-gray cable from the *THING* board goes to J136-2?????
Can I just cut the bad soldered cable and move the cable from J136-2 to there without damaging something?
