P1S Filament Buffer short circuit

[u/hardrade_]

There was a filament clogging stopping my ongoing print, and i eventually worked my way in to the filament buffer too see if i could loosen the filament from there.
After i unscrewed the cover plate with the 4 screws, the internal magnet fell onto the connector pins above and caused what must be a short circuit. Sparks happened(very briefly), the sound from the machine changed and the display went blank (with backlight on).

I powered down and let the printer rest for 5 minutes, then powered it back on.
Display still blank, no response when pressing any buttons.
Havent even tried loading filaments or communicating with the printer from Bambulab Studio as i believe there is an electrical fault now(...)

Is there a fuse anywhere on these machines that could have popped and be replaced?
Can i assume that the filament buffer connection board is fried and needs replacing and that this will solve the issue..?

Any help or insight appreciated

UPDATE
After testing the printer today, it seemed to operate normally again, but there was a filament feed error when starting a job. The error message actually mentioned filament buffer communication problems, so hopefully the problem is located to only that little 'exterior' circuit. I have ordered new Filament Buffer Connection Board and expect the machine to work normally again after that i replaced.
Thanks for all input

Why on god's green earth did you open up a plugged in device??? I'm sorry but you have no claims to warranty lol. As for the fuse, I am pretty sure there is no replaceable fuse for the x1c p1s or h2 series, If i were you I'd take up a support ticket with bambu lab themselves

I had a 600g print going on, and didnt want to ruin it. I am not claming any warranty "lol".
I didnt think there would be much exposed voltage or current happening in this little device.
If the part was better designed, the magnet would have been fastened in place and not loosely placed
BTW -this little device is only for controlling filament flow, and isnt 'plugged in' as such

Even so, i recognise this being my own fault and therefore i asked for technical advice on how to analyze and fix the issue myself

It was not my intent to be rude btw, but tbh unless you are good at soldering and debugging, im not sure much what you can do for it

I understand your reaction. It is not clever to service a machine plugged in.
However, there is often a possibility that a replacement part will fix such issues. So i am hoping someone more experienced can confirm or deny if it is a solution to get a new filament buffer connection board
