Ender 3 V2 will not respond
Can anyone help, it switches on and there is power to the screen although it is black. I have managed to re-flash the screen, from blue to red. When it comes to the main firmware I cannot get it to respond at all I’ve tried various bin files with no joy. The machine does sound like it’s powered on, fan is the working power to the screen seems fine it just will not start up. Help !
