iPhone boots up to logo but then stays at a black screen. Suggestions?

I have an iPhone 6+ and until recently I had purchased a new screen for it because mine was shattered. It has been working for quite some time up until I replaced the screen, not the only time I have had to replace it. I replaced it in 2016 and then had to replace it again recently. It has ghost touch glitches every once in a while but its had that ever since I had the phone. Anyway, the phone started booting up to the apple screen and then looping. I’ve connected it to iTunes and tried to diagnose the problem by restoring and updating it but to no avail errors were popping up and the phone would start looping during the restore process causing it to error and fail. I noticed that the phone does hold charge because after taking it off the charger it continues it’s loop cycle, it does not show the dead battery icon which is strange to me. After charging it, it started up and shown the apple logo then black screen, still powered on though then minutes later it will shut off. Is it a hardware issue, loose connection, malfunction?

Ps. It has not been exposed to liquid.
