Problems with LCD panel and Changing Filament

Hi gang,

I havent used my snapmaker for a while. I’m trying to change the filament and when I go into the menu option, the nozzle will start to heat up, but at about 45 degrees, the target temp changes from 200 to 0 and the nozzle cools down again.

Then if that weren’t problem enough, the LCD panel freezes and I cant even exit the menu without turning off the whole machine and turning it back on.

I have tried updating the firmware. If anyone has a solution I would greatly appreciate it!
