Half of one of my RGB 16x2 displays has gone bad (see attached photo). The first 8 characters of the first and second lines are fine, but the last half is blank and then has solid blocks for the last 3 characters (and a line).
I have tried another display on the GrovePI and it is fine, so it is actually an issue with this specific display.
Is there a simple fix to this or is this a hardware failure? If the later, what is the warranty on it and how do I get it replaced (I am in Canada)?
