iPhone 6 Plus with no display. Advise

Hi, I got a iPhone 6 Plus for 5$ knowing it was not working. I was told the phone has Touch IC Disease and after letting it charge for awhile there is also no display at all. I am thinking of repairing it. I can easily replace the screen but the touch IC I would have to let a pro repair that. Sense it is a verizon iPhone and i have verizon i might use it. Any ideas?

Forgot to mention. It power on fine as i can plug it into my computer and it sees the phone perfectly. It also does not vibrate when the switch is changed nor plugged in.

After talking with the original owner of the device i asked about the vibrate and he said that it stopped working about a year ago so either way i will have to fix that if it want to fix this phone. As for the screen i think replacing it will bring it back to life but for the touch IC i would have to send it to someone who handles those repairs.
