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.

Had a smiliar problem after changing the fan on the Orange pi. it was down to the plastic cable that connects the Pi to the NVME was very slighly loose and wanst giving a good connection! Had to give it a really good push in again. took ages to figure it all out without it you get nothing apart from a light flashing on the pi's an the fans at full speed. Once connected probably i started to get a light again on nvme and it booted up.

hope this helps

Thanks for your suggestion. I opened the miner and looked at the cable connections. I removed the whole NVME board and cable and connected it again. Didnt fix the problem.
Full Fan and no red light on front.

A red light comes on, on the hash board near the fan plug. Ethernet port blinks green (no yellow)
I believe there is a red light that comes on, on top of the Orange Pi.

The NVME board does not have a red light on
The hasboard on my old unit has two green blinking lights near the Ethernet port, this newer broken unit does not have those lights active.
My old miner has a green light underneath the Pi, the new miner does not.

If the NVME board is broken, would that stop the miner from properly starting up, or is that just for the node?
Maybe the Pi isnt able to read the SD card?

What else could be an issue?
