MacBook Pro 2017 A1708 Backlight but no Display

Received a macbook pro 2017 model A1708 EMC, it turns on with fans spinning and a backlight comes on, but no display or apple logo. It is receiving the correct amount of power. It does not display any image on external monitor. Caps lock key displays LED green light. Is this a motherboard issue, software issue, or just needs a new top lid assembly?
