Ender 3 V2... only playing with thin since January, somewhat successfully until recently. Using a file previously used (successfully), I needed to print the item again.
Whenever I attempted to set the nozzle temp, i could do nothing more, and a blue line crossed the screen from left to right and the screen reset as though I had just turned the printer on. Creality have not been of much assistance. That said, it is suggested a thermistor (I’m new to this and had no clue what it was) has failed.
Creality want me to unplug the nozzle port from the motherboard and report back with a temperature which will apparently appear, and I have no idea what port that might be!
Motherboard is V4.2.2
It is simple if you know, but I don’t know, so it is not quite so simple.
Thanks in advance for any help?

hi，@Heykid41 Refer to the picture, unplug the wiring of the nozzle thermistor, check whether the nozzle temperature display is -14℃, if so, the thermistor is damaged, please replace the thermistor, if not, then the motherboard is broken, you can replace the motherboard. You can refer to the videos for replacement.
