Hello all!!

Been mining for the past 3 years and read through the whole thread in that time.
But now I have a question and problem.

I've got a batch 3 Apollo BTC Full Node that has been running flawlessly for years on Turbo.

About two years ago I got a batch 4 or 5 Apollo BTC Full node and that's when everything went wrong.

Long story short, as I was setting it up, I didn't realize that I cannot hot swap the HDMI monitor between both units so I thought the unit was broken, when nothing showed on screen.
I turned the new unit off and on, switching cables, and ALSO connecting BOTH MINERS via micro usb to micro usb cable on the OrangePi plug.

I thought that was one way to swap settings from one unit to another, not realizing that is only the case for hooking up a Standard Unit to a Full Node. But not with that cable ;(

Since that first initial setup phase, I have not gotten the miner to work.

The new Batch 4/5 miner blasts the fan at 100% on startup and I dont have a red light on the front.

I've copied the Bitcoin Blockchain from the old miner to the new miner's SSD and I bought a new SD card and flashed it with the newest OS.
Nothing. Fan Full speed and no light.

Doing a side by side from the old miner and and the new one, the new miner does NOT have a light on the bottom of the Pi, it does NOT have a light on the SSD board, and the ethernet light blinks yellow (or green?) but does not have two lights blinking and flashing.

Hash Board gets power from the PSU and part of the Pi works.

Are my boards damaged? What's the next step?

Thanks for any help.
