I received my replacement Displayotron 3000 yesterday (Order #14859), but it seems this one is having backlight problems similar to the first, this time with the right-hand LED. Initially it worked fine but within a couple of hours the red element of the RGB had stopped working entirely. Pics here: (the effect is more pronounced in reality, and zeroing the HSV values makes no difference):
This has been tested on a Pi model A and a B+, with a fresh install of Raspbian (2014-09-09), following all the instructions on the dot3k GitHub page, and using a ModMyPi HQ 5V 2A power supply.
Much as I like the dot3k (it’s an LCD with RGB LEDs, what’s not to like?), two wonky ones in a row is a bit of a pain. Could you possibly organise a refund for me, please, and I’ll return this problem one.
Thanks in advance.
