MK3S+ LCD not responding
I am currently having trouble with my MK3S+ because it couldn't turn on the LCD screen while the power is on and the fan on the extruder is moving. Like everything seems to turn on because the green light is flashing in the box and the fan is turning, but there is nothing happening with the LCD screen.
RE: MK3S+ LCD not responding
Cable or connectors between the control board and the LCD board or panel snagged?
Try to remove and reinsert them in case of a bad connection.
I also saw some bad solder contacts on the pcb at the pins. A small magnifier is a great help here.
Are the pressure links between the cable proper and the connector well pressed so the "vampire" hooks make good contact. A quick check with an ohm meter will be useful.
If that does not work remove the sd card and measure all the voltages to the lcd board and on the control board.
Good luck with it.
