Okay, so based on your posts and the CGMiner API log,
- PMU (power management unit) board is ok based on the CGMiner API log and green LED indicators.
- AvalonMiner LED indicator goes red.
- AUC3 converter LED indicator goes red.
Hash boards do not start hashing and all values are shown as zero.
But I find it hard to believe that both 2 of 4 hash boards you are powering are completely dead.
Based on the weird hash board values and what I've repaired earlier, I'm estimating that you have a faulty control board (MM board).
