So my ende 3v3 stopped working. The company sent me a new mother board which was switched out but now when i try tk turn it on. I can see lights. The light on the printer head flashes and the screen wont turn on at all. Any ideas?
Hello @Mercadiechurch21 …! 
Welcome to the Creality Forum…! 
Just checking to be sure that when you were putting the printer together make sure the voltage switch was set to a setting your country uses.
Yes. I remember double checking it before. It worked for a few months until it stopped. But after i replaced the motherboard and stuff the screen wont come on and the LED on the printer head underneath the logo wont stop flickering.
