One loud beep and a blank LCD screen
Hello.
Something happened to my printer: after printing is finished, i cannot access the control menu and unload the filament from the extruder.
I pressed the reset button, and after turning on the 3D printer, one loud beep and a blank LCD screen appeared.
No reaction to pressing the control knob.
I cannot connect to the printer via Octopi (raspberry pi zero w + octoprint) or control the printer through its control panel.
What I was trying to do:
1) Reflash firmware;
2) Restore factory settings to shipping prep;
3) Disconnect everything except power cables and two cables from the LCD display;
4) All three fuses (5-5-15) are checked - they are all alive.
Current firmware version 3.5.1.
I can upload the firmware update log if necessary. But there are no error messages.
But I still get one loud beep and a blank LCD screen after confirming the Z-axis calibration function (it remains after resetting to factory settings).
These loud signals are similar to diagnostic codes. What do these signals mean?

New simptome: Y and X motors trying to reach Home position but didn't stop when edge reached and trying to breach the wall. They moving very-y-y slowly.
Not sure why, maybe it appeared after i press Home button at Pronterface or controller board trying to execute the Z-axis calibration function.
Didn't notice that before.

The problem was solved by completely resetting the printer data.
Thanks for the help.
