White screen on when i printing about mks-robin-nano-v1.x HOT 12 OPEN

I have the same problem on Mks_Nano35 V2.0.3.3. Are you printing from Octoprint or the SD card ?

from mks-robin-nano-v1.x.

SD card, the fw 2.3.1 works fine

from mks-robin-nano-v1.x.

You can try to update firmware to latest version

from mks-robin-nano-v1.x.

i am also having this problem with 2.03.5. it only happens about about an hour into printing once the display has gone to sleep. when i touch it to wake it up i have a white screen the rest of the print

Can you provide some picture to me when you printing?

from mks-robin-nano-v1.x.

Just a solid white screen. Been printing about 3 hours.

from mks-robin-nano-v1.x.

Is printing still in progress? Just the screen cannot display information?

from mks-robin-nano-v1.x.

Yes the printing continues and finishes however the printer has to be power cycled before the screen will start working again

from mks-robin-nano-v1.x.

What seems to affect the display

from mks-robin-nano-v1.x.

Exactly the same thing happens to me, after 2 or 3 hours of printing, I have to turn off the printer and when I try to load filament (outwards) the Z rises.

from mks-robin-nano-v1.x.

Noticed the same on a TwoTrees Bluer printer with Marlin 2.1.1
Sometimes this happens directly after starting the printing process via OctoPrint.

Printing process is not affected.

from mks-robin-nano-v1.x.

same for 2.0 bugfix release (Marlin 2.0.9.2) by mks and onwards versions by marlin. probably a bug of lvglui and not about fscm cable. couldnt replicate with marlin color ui.
