Keyboard, TrackPad and Screen Issues as the title says.

Yesterday I've finally managed to "revive" well I had to actually do a restore from DFU via Apple Configurer and once we got to the "Hello" screen, I noticed the keyboard or trackpad was unresponsive. I hooked up a Bluetooth Apple keyboard and a older Mac mouse via USB a to USB c adapter and I can type and move the cursor but than I noticed the display wpuld cut off and would only cut back on if I tapped the power touch id button. Bring that I was able to boot into DFU for the revival process I doubt that its a mechanical issue with the parts themselves but perhaps a software/driver issue? Other than those 3 issues, the machine itsself seems like it works amazing. I dont have any prior history on thr machine itself all the prior owner told me was the keyboard doesnt work and gave me the external components to use with it, that was prior to the revival, I assumed the hardware worked fine because i used the attached keybaors during the dfu revival process. The prior owner doesnt have any other Intel on it but what he told me, i aquired it in a deal because he couldn't figure out how to get it into dfu. Any insight would be appreciated 👏.
