I have an issue when using the Raspberry Pi 7" Touch Screen Display connected via the ribbon cable (DSI Interface). The issue is that after most reboots, all I get is a blinking cursor in the upper-left corner of the screen.

This issue is intermittent.

What logs should I look at to diagnose this issue.

I do not have a space issue on my SD Card, it's only 10% full

I am on a Pi3B+
