Surface book no display, working touch

I recently purchased a Surface book Core i7 2.60GHz 16GB RAM 512GB SSD 13.5’’ laptop. I knew there was a display issue when I purchased it.

I went ahead and plugged the surface book into an external monitor and everything works just fine. I went into display settings and noticed that Windows was only picking up the external display and when I attempt to detect displays it is unable to find the clipboard/tablet screen. I haven’t opened the device up yet, but I’m curious if the issue actually is the screen. The touch digitizer appears to be working as expected so that makes me skeptical of the LED screen being broken, but I figured maybe the LCDs aren’t working in the screen. This doesn’t line up with the fact that Windows doesn’t seem to detect the screen at all. I tried using the keyboard hotkeys to adjust screen brightness but not even the brightness change dragger popped up on the external display.

Is it possible that the display ribbon cable may have come detached during a drop or something (I’m not fully aware of the devices history)? From what I understood, these have metal cages over them to prevent anything like that from happening. I will add that there is a slight deformity in the display along the top left edge. It looks like the device may have sustained some damage there but the touch digitizer is still working in that region and with a flashlight on the display I don’t notice any obvious cracks in the LED panel. Also, I have my doubts that this would prevent Windows from being able to detect the device.

Has anyone dealt with a similar issue on a laptop/surface book before? I’m having a heck of a time finding anything online.
