Hello,

I am new to 3d printing, and recently purchased a Tevo Flash. Everything was fine till after several weeks of use I tried to update the firmware. After flashing though, the LCD (while turning on) remains blank. Being my first try, it is entirely possible I didn't flash the correct marlin or something, but after many different tries I downloaded the original Tevo Flash firmware, and flashed that. Unfortunately the LCD is still not functioning.

When connecting the printer via USB and opening Cura, I can preheat the nozzle just fine, the tempteture reading is stuck on 111 degrees though, and the bed temp is not displayed. I've tried lots of fixes, from trying to change the LCD contrast to enabling different LCDs in the configuration.h file in Arduino. Any help with this issue would be greatly appreciated.
