Hi guys, Received my L3+ yesterday and I was so excited Grin

, however, the excitement didn't last for long, seam mu L3+ is now working only on 3 hashing boards Huh

Yesterday I notice that 4th board was having ASIC# 36 instead 72, and today when I powered up the miner only 3 hashing boards are showing.

Now what to do before writing to Bitmain???

I have tried switching on and off the miner and changing the PCI power connectors but no use.

I am using APW3++ on a 240V power grid.

Any advice is appreciated before I raise a ticket with Bitmain

Double check if the PSU is feeding the 4th board with the appropriate power.
If that doesn't help, read issue 6 here:
https://bitmainhelp.zendesk.com/hc/en-us/articles/220872007-Possible-problems-for-Antminer-Troubleshooting-for-S7-S9-L3-

Tnx man, ok I did everything and the final outcome is: one hashing Board is Dead Undecided

Now I have removed the Hashing Board from the miner and packed it as instructed from Bitmain, but I have one confusion. When I go to raise the ticket for repair on the Bitmain site it asks me for the tracking No from the courier. Then I need to print two copies of the ticket and put one inside the box and attached the second one on the outside of the packet. So how can I get the tracking No before I take the packet to the courier, only after submission of the packet they will provide me the tracking No.

Does anyone have experience sending damage hashing bord to Hong Kong repair center? please help

P.S. the miner is working fine on 75% of its power so it gives around 377 mh/s, room temp is set on 25⁰C, chip temp 54-59.
