MK3S won't boot up, fans keep spinning

Hi,

 

This morning, after printing, I shut off the printer. Now, switching it on, it doesn't boot up properly:

  • Both fans just keep spinning,
  • The display keeps showing "Original Prusa i3 / Prusa Reasearch ..."

and it stays in this state. Factory reset doesn't work (no beep) after reset+knob. Latest firmware is installed.

Both outputs on the power supply measure 23.7V. Didn't open the rambo case yet.

 

Any suggestions?

Well... took it out of the enclosure, hooked up the power supply and LCD again for one last test before doing some serious bug hunting and much to my surprise it booted up nicely. No loose cables, connectors as far as I could see, but it's alive! Happy!
