2 Black/Blue Lines Across LED screen

Mon Sep 11, 2017 4:13 pm


I have recently upgraded my Prusa i3 to the Prusa i3 MK2. The upgrade went very smooth, and the instructions were really clear. I am having issues where the LED screen is only displaying 2 horizontal black/blue lines. I have triple checked to make sure the connections are correct, and they are. I have also made sure that all the firmware is up to date. Can someone please provide some assistance.

Hello Michael!

Did the display work correctly before the rebuild - i.e no issues at all?

The two flat cables are different - have you really inserted the right cable in the right socket (they are marked - asking just to be sure)?

If all are well - then I cannot think of anything else that the display might have got electrocuted by a static discharge.
