My A350 doesn't want to play with me anymore!

Hello friends! I got a problem when I wanted to make a filament change! Here’s what happened. After the filament roll was finished, the display showed me the appropriate notice. To start the filament change, I pressed the touchscreen. Since then, you can only see the “S” on the screen. I have tried everything but nothing has helped to restart the Snapmaker A350. What can I do?

Oh no

The screen isnt booting to the control software?

Perhaps try to shut down, unplug for a few minutes to allow all residual voltage to disipate, unplug the touch screen

then plug it back in, power it back up

if it continues to get stuck on the boot image
