LED display screen turned white and the machine made a long, piercing sound
Hello everyone, I am a newbie. My machine MK2.5 MMU2 suddenly lost power when updating the firmware yesterday. When I restarted the machine, the LED display screen turned white and the machine made a harsh beep. I am very scared. Is there anyone? What's the solution? Thank you.
RE: LED display screen turned white and the machine made a long, piercing sound
I have a MK2.5 for about a year now. I and know the feelings at start when something looks strange. Panic on the machine is mostly more panic in myself. You will learn to live with that. 🙂
Now to your issue. Steps I would go for:
- Power the machine off (you probably already did); power plug out; wait about 30 seconds (to be sure you will have a "cold reboot".
Power plug, power switch on. And wait. You might be lucky it works now. Probably not, so you get the beep and white screen again.
But just to be sure, because in next step you will loose all settings on the machine. You will have to recalibrate everything 🙁

Read and execute, it will bring the machine back as it was.
Then update firmware.
And start calibrating.
We will do what we have always done. We will find hope in the impossible.
