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)?
If another display works then it might be a hardware problem. Was the RGB display working before and do you remember when you started seeing this. I have seen these displays go bad if a bad voltage is applied to it or if they are kept in too harsh environments. Also, where did you buy this from and when.
Thanks for the response. We purchased 10 kits back around the middle of January this year. This particular display has been sitting on my desk at the office for a couple of months, so not a harsh environment. I assume our power is relatively clean, since we have a lot of other electronics in the building. I will contact the company we purchased it from and inquire about the warranty on it.
