Default [Q] Screen Random Freezes - After Replacing Screen

Alright, after much angst and struggle (got the wrong parts etc.) I finally was able to (successfully?) replace my Nexus 7 2013 screen. After charging it and excitingly using it after 2 weeks of it broken I noticed something peculiar. Every once and a while my screen freezes up, the touches are still there as I can here taps and audio, but the screen doesn't show anything new (just freezes). I simply lock & unlock my device and it returns to normal.

I just reset my tablet and it sadly still persists. I would prefer not to have this broken as we learned the hard way when not using a static band when replacing my dad's Nexus 5 screen (it's been a bad tech year for us).

Just a FYI and summary, Just replaced my Nexus 7's screen and digitizer assembly, not it randomly freezes the screen and a quick lock and unlock fixes it.

Any advice? Thank you.
