Black lines on pitft 2.8

by dedpxl on Sat Aug 12, 2017 1:05 am

I was able to successfully boot my pigrrl 2 but after turning it off overnight the only thing I can see on the display is vertical black lines moving as if it is trying to display the Retropie splash screen. I reseated the ribbon cable on the tft assembly and all cables that run to the display and pi respectively. Is my screen defective, am I missing something?

This is what it looks like as it initializes during boot up. Black lines appear across screen and then it goes white display and stays that way. This is with external power directly to the pi and also running of of battery through the powerboost 1000. I tried a second display as well and the issue persists. I also reimaged the sdcard and redid the easy setup for the pitft and issue persists. I am running out of things
