Hi there!

I would suggest the following:

  1. Disconnect/remove the display.
  2. Inspect the display ribbon cables for any pinches or tears and inspect the connections and contacts on the logic board for any damaged pins.
  3. Use a Q-tip dipped in Isopropyl/Rubbing Alcohol to clear out any debris in the connections and contacts.
  4. Re-secure the display connections and reseat the display.
  5. With the new screen installed, power off the device and let it sit untouched for at least 6 hours.

If this doesn’t help, it is possible that some sort of damage did happen during the repair or pins on the connections on the display or it could simply be a bad display. Hope you are able to figure it out though!

Probably just a bad LCD but you might be able to reseat the lcd ribbons. Most likely a screen replacement.

There is a chance that the new screen for the iPhone 6 was not replaced properly, and your friend might have done something to dislodge it accidentally.

It might be best to take the iPhone to a shop and have a technician replace the screen.
