OK. So my big plan for this year was to dump quite a bit of cash and move HEAVILY into RGB. Unfortunately work got in the way, and by the time I could research it was far too late to order. So I'm stuck with 3 old LOR A/C boards which is disappointing. What is catastrophic however is that one of them, my oldest one, is out of commission it would seem. No status light showing whatsoever. It looks visually OK (It's an older CTB16PC board only). I've tried switching the A/C inputs, no go. I've switched the fuses both internally (left to right) and externally (swapped with my housed CTB16's) and no go. I know how to diagnose and fix a triac, but in this case the base power seems to have died somewhere. Are there things I can check, or am I going to have to downgrade my show for this year?
