The Anycubic Photon Mono 4 printer—though this isn’t really important—has only printed 2.5 liters of resin; I don’t know how much resin it uses. Anything below the horizontal line just breaks and prints some kind of nonsense.
Are you sure it's the LCD screen? I don't want to buy a new one only to find out the problem is with the motherboard, since the pattern isn't changing—it seems like it's the screen after all—but I'd like to know for sure.
I was printing at a room temperature of 22–27 degrees; it didn’t drop below that. I followed all the instructions, but when I printed a lot in a row, I didn’t drain the resin from the tank for a long time. Of course, I checked for debris in it before printing, but maybe I missed something and the screen just broke; otherwise, I don’t know what the problem could be. Also, since I live in Ukraine, I had frequent power outages in the winter, there are no visible screen damages.
In short, how can I prevent this from happening again?
