Niether ips displays working

I have a lattepanda alpha and i have both the 7in and 10.1in. When I plug in the LP with either the 7 or 10.1in nothing comes up red light flickers fast then goes normal, then it stays solid like normal boot then i press the power, the blue light just flickers. But when I connect to hdmi it works.

If i could get some help o greatly appreciate it.
Thank you.
