Hey! I actually figured out that I fried part of my board because on top of this problem I've been unable to heat my extruder.

This happened to me and it turned out that while putting a spool of filament into the back of the printer, I had accidentally cut the flexible flat cable (FFC) that connects the LCD and buttons to the mainboard. It comes up the back of the printer from the main board, follows the top around the left side, then comes down the front to the display. I accidentally cut it at the back of the printer by somehow pushing it into the metal frame while trying to insert a spool. You should probably just make sure it's connected at both ends and intact.

The symptoms were exactly the same - buttons worked but the display was blank. I suspect it's just that the LCD control/power lines are on one side and the button lines are on the other.

Hello,

So I was installing my E3D V6 on my Da Vinci 1.0A when all of a sudden my LCD goes blank. No light, no bars, nothing. I wondered if it was a faulty LCD, but it's interesting that the buttons on the LCD still work as they still produce a noise when pressed so it's just the screen which doesn't make a whole lot of sense. Anyone care to help me out?
