A couple more details I forgot to add in the original post:

- Resetting the device (paperclip in the pinhole) also causes the power button light to flash, but the screen still does not change

Created a photo, should show here (first time adding image). Kobo "on" and backlight on. Photo angled as that was a quick way to avoid any shadowing on the screen caused by the camera and me.

Curious if anything new occurs to you. At this point it seems likely the device is a goner.
From what I can see, you haven't tried a manual factory reset. The pinhole reset doesn't do this. It just forces a power cycle. The factory reset instructions are in the Wiki. I don't think it will help, but, you should try it.

My guess is that the backplane is cracked. The blank power off screen is probably the worst one for showing that as it is a uniform black. If it was an image, you might see the problems. But, they can also be around the edge and not visible. If you open the device, and look at the back of the screen, it usually becomes obvious.

At this point, it might be worth opening and checking the screen and any connections. The light and screen are on different cables (in the devices I have opened at least), so the screen could have come lose. And you could try to reimage the internal SD card if there is nothing obviously wrong with the screen.
