Greetings
Firstly I should explain I have decades of experience building, modding and repairing x86, but almost none with non-x86 so though I've read quite a bit, I have yet to see deep fundamentals that help me troubleshoot my problem.
Problem - Upon PSU Power On the RockPro's green LED and (a bit oddly) both ethernet LEDs light up with no ethernet cable connected. The RockPro power switch does zero, no matter what is connected or disconnected down to power cable. The White LED never lights and the CPU Fan never spins.
Possible issues - I'm using a gutted CoolGear dual 3.5" eSATA drive bay enclsurtewhich apparently has a PSU capable of 40-50 watts, so well above the 3A @ 12V required. Not only did I check docs for proper polarity (+ on center, - on barrel, right?) but no LEDs should light up if polarity is a problem.
I bought the board, hs/fan, and PCIe > SATA (not yet mounted) from respectech on ebay. The company seems fine but have others had any difficulties with DOA replacement?
Am I correct in assuming that the board should at least attempt to power up with nothing connected but power? What can I research and check?
I'm a rank newb at SOC/SBC so any help is greatly appreciated. I'm completely committed to exploring Pine 64 RockPro64
