hi guys, i have a prusa i3 (this diy kit [www.emakershop.com] )and since a couple of days i'm struggling with my g3d lcd, it has becomed unreadeble as shown in pic [www.dropbox.com] .
It has worked nicely for a couple of months (even if the sd reader never worked), sometimes it has shown wierd characters, but everything was restored as soon as i pressed the encoder and enterd in the menu.
Now even if i press the encoder nothing changes. I've tried to unplug the shield from the board and replug it and nothing has changed, I haven't tried to unplug the cables because i don't know how to do it without damaging the connectors.
I also tried to revert to a version of marlin i used before and still nothing changes.
One strange thing happens during power on and initialization: if i remember well in the first few second on the display were shown two lines of squares, now this thing dosen't happens..
Is my LCD gone?
Thanks
cheers
