I have a Geeetech Prusa Mk3 pro A printer and the small part failed after 16 months is:

'Click button'- Alain called it many posts prevously
or call it.
'Rheostat' - contol knob / push button
It is in the front part of the power supply / control box that has the emergency stop button, the lcd display, SD card reader and the knob.
Mine says "GTBOX_lcd_board 2015 V1.1"
I can't scroll thruogh menu options.

has anyone had this trouble?

Is there a way to buy just the rheostat? front panel GTBOX_lcd_board? or must I buy a whole new power supply / control box?

I want to know if your printer can print through the USB serial port, so you can confirm whether it is the problem of knob button beside LCD.
