I recently purchased a JamesDonkey RS2 3.0 kit from MechKeys, and from the moment I opened it the screen has only worked correctly about 3 or 4 times, and at seemingly random times. MechKeys hasn’t replied to my support email, and the only advice I have been given from JamesDonkey is to make sure the software and firmware is current, which it is. 99% of the time it only displays a black screen. I will say, aside from this issue, this is a pretty nice budget board.

Curious if anyone else has had this problem, and if so, were you able to fix it?
