Hello fellow Redditors,
I'm currently encountering an issue with my Antminer L7 and I'm seeking guidance on how to resolve it. Here are the error details:
time="2023-04-29 18:11:33" level=error pid=918 msg="miner has no sn!" time="2023-04-29 18:11:54" level=warn pid=918 msg="power voltage can not meet the target! centi_voltage 1600 min_fb_vol 0.000000 qualified_vol 12.000000" time="2023-04-29 18:11:55" level=warn pid=918 msg="power voltage can not meet the target! centi_voltage 1600 min_fb_vol 0.000000 qualified_vol 12.000000" time="2023-04-29 18:11:56" level=warn pid=918 msg="power voltage can not meet the target! centi_voltage 1600 min_fb_vol 0.000000 qualified_vol 12.000000" time="2023-04-29 18:11:56" level=error pid=918 msg="check_feedback_voltage error!" time="2023-04-29 18:11:56" level=error pid=918 msg="power init error!"

I have already tried disassembling the device multiple times and thoroughly cleaning it. However, the issue still persists. I am particularly concerned about the "power voltage can not meet the target!" messages. At this point, I'm unsure which component to replace for testing purposes due to the associated costs. It could potentially be an issue with the PSU (power supply unit), the control board, or even the hash boards.
If any of you have experience with Antminer L7 or similar mining devices, I would greatly appreciate any assistance or troubleshooting suggestions you can provide. Additionally, if you have any insights on which component I should prioritize for testing or any other relevant tips, please share them.
