hello @all,
my USB out from the SunControl Board delivered the days only ~ 2 Volt. After a short push on this black box (marked orange) - Transformer? - it was ~ 5 Volts again and the Pi Zero booted.
In case of low voltage the camera beeped although the Pi Zero had no LED activity.
The board was installed at that time - so it is possible that the pressure moved the whole board or was this a coincidence? By switch off/on I did not get the 5 volts.
The board is now removed and the error is currently not reproducible. What can I test before the board is removed?
best regards Joe

That is an inductor. Don't push on the chips around it, but I'll bet somehow the inductor came loose. BTW, the low voltage makes sense if the inductor had come loose.

Whoops! My name is BP, not BO. My fault.
I don't know why it came loose. You may be able resolder the corners.

Hello BP,
i looked at the corners, i don't see any loose corners for re-soldering. however, it would be too hot for me, because there is very little space. on the back side of the board i don't see any solder joints, so i assume the board is double layered?
what else can I test or measure?
best regards Joe

Joe,
I think you might be out of luck. It's an SMD part which are devilishly hard to fix.

Hello BP,
that's stupid, the station ran for exactly one week as a test :/ Open a warranty case by direct mail?
best regards Joe
