Black screen, Blue LED, already tried factory reset, clear cache.

Note 5 (Verizon). Over the weekend I replaced the LCD screen and battery. Phone screen was broke about a year ago after being dropped, phone sat for about a year prior to repair. Phone will turn on, it shows the usual "Samsung Galaxy Note 5" boot screen, but once that loads, it goes to a black lit screen, with blue LED notification light to left of speaker. Phone does go into recovery mode and I've attempted to reboot in safe mode, cleared the cache, and also tried to do a complete factory reset/ data wipe. Still nothing, only loads to the black screen; it's like it's missing the software or something. Not sure where to go from here.
