Hey everyone,

I’ve run into a puzzling situation with my Lucky Miner 08,
and I’m hoping someone here might have some insight.

I’ve noticed that the miner is only drawing around 50W,
which is obviously too low for normal operation.

I’ve tried a variety of original settings—like holding the reset button for 10 seconds,
adjusting voltage and frequency channels, and even a full power cycle—but the power draw remains stuck.

Initially, the ASIC Voltage Measured in the interface was showing 0V on the right side.
In the logs, I saw something like:

₿ (241631) power_management: 7F vout: 1.24, iout: 33.69
₿ (241631) power_management: 24 vout: 0.05, iout: -0.29
₿ (241631) power_management: 14 vout: 0.05, iout: -0.28
```
(The numbers aren’t exact, but basically `24` and `14` were both reporting around 0V.)

I opened up the machine and measured two sets of 12V rails; both read a solid 12V. I also tried reseating the heatsink. After putting everything back together, there was a brief period where things looked normal:

₿ (126451) power_management: 7F vout: 1.24, iout: 33.69
₿ (126451) power_management: 24 vout: 1.24, iout: 29.75
₿ (126451) power_management: 14 vout: 1.24, iout: 29.47

But then it switched again, and now it’s showing:

₿ (241631) power_management: 7F vout: 0.05, iout: -0.29
₿ (241631) power_management: 24 vout: 1.24, iout: 29.25
₿ (241631) power_management: 14 vout: 1.24, iout: 29.34

So in other words, `24` and `14` are back to normal, but now `7F` is reading 0V.
The interface also shows some voltage in the bottom-right corner,
so there’s at least some power going through.

Here are my main questions:
1. Could this be related to the way the heatsink is installed, or does it more likely indicate a problem with the power module/VRM?
2. It doesn’t seem to be a super rare issue. Among five to ten units, at least one has exhibited this behavior.
3. Does anyone have any recommendations or fixes I could try?

Thank you so much for taking the time to read this.
I’m relatively new to this,
so I’m trying to give as much detail as possible.

Any help or suggestions would be greatly appreciated!
