Maybe someone can help me brainstorm on an issue. I have a A4+ that had 1 chain down day after arrival from Inno. Board would light up green then the light would go out after bootup. Board never hashes. After trying to swap data cables/PSU/firmwares/data ports nothing resolved the issue. I contacted Inno and had the board sent in under warranty and they replaced the board. After swapping the board all 4 boards worked for a few days. Now the exact same board from Inno is having the same issue. Very odd...
