It is wide open 5-12v is recommended I think but you can go all the way up. I am not actually sure which side powers the LCD though. might not actually solve your problem.

I have had the issue before. But have not seem it in a long time. I think the boards are pretty solid now. I’m not really that familiar with it. When I test them I plug everything in and either the regulator pops or not. So its either cold or it popped.

I can only say make sure your SD card isn’t hot. That is the only time I have seen it in the last year or so.
