Replaced the screen.. I forgot to disconnect the battery.

I replaced my screen because of an annoying scratch (my fault) on the original one (followed the oem parts# supplied by Lenovo). After turning it on, nothing appeared on the panel, but the computer ran fine with an external monitor. Keyboard, trackpad, trackpoint, wifi and webcam all work

I tried plugging in my original scratched screen (which worked) and that doesn’t work now.

So I figure it’s the ribbon connector (I yanked too hard), and I even ordered the part from Encompass. Then I realized I forgot to unplug the battery! Assuming the replacement cable doesn’t work, how badly did I mess up? Is my screen nuked? Or did I trip some kind of fuse on the mainboard?

It’s a non-touch screen display btw. Not sure if that makes any difference.
