Ender 3 - Blank Text Screen thoughts?

Hey, it may be easier to point to a Reddit post I made which has all the details, let me know f you can’t see it. I wanted to try one of the latest firmware builds you made, but it did not work. When I start up it just stays blank

Any thoughts? If not, that’s fine. I was trying to figure out how I can tell a LCD screen versus a MB problem. Also, if you have a preferred MB replacement (if it is probably dead)?

Thanks for doing this, its cool!

(I see some similar posts here, I’ll be reading through those.
