a few days ago while heating up for a print my ender 3 pro's screen froze up and the bed was not hot. I turned it off and back on then when it was back on the screen was just blue. tried turning it back on and off a few more times but the same thing. then I searched up the problem and I tried all of the fixes but nothing worked. I also tried re flashing the firmware with an SD card but it didn't help. when I hold down the knob on the screen for 15 seconds it doesn't click at all. when it is turned on, all of the fans turn on. It also does have a sprite extruder on it. Is there any way to fix it?
