Cointerra not booting? Can't ping, red light CTR1 - no other lights

I have been running this Cointerra miner about 6 months and it's started giving me fits. It would just stop responding, so a power cycle got it online, but now that is no longer working. I read through some of the big thread, but I think I need some specific help. Here is what I have done so far

Opened the cover and tried booting, board 1 has green lights that come on, go off, then do the knight rider thing, I think that's what they are supposed to do? Board 0 does much the same thing but the lights are orange, not green. So I think I can assume my boards are not dead.

I switched the power supplies, get same result. Checked voltage on both boards and they are getting 12v, so that looks good.

I reseated all cables on both boards, no change

The controller board underneath board 0 has blue lights on it, but I can't ping it at all any longer. Should I work on getting the controller online? Is that likely where my problem is and not the boards themselves? I have looked the boards over very carefully and I do not see any burt chips or smell any burnt smell at all. They appear to be in great shape. Is there any kind of program I can run and connect to the boards USB with my laptop and check anything?
