I accidentally attached my LCD cable with the battery still attached!

I have a Lenovo 330 15IGM. (I believe it’s the 15IGM, no where on this laptop is there anything more descriptive than Ideapad 330.)

I replaced a broken hinge and display back cover.   The new back cover came with and I used the new WiFi and LCD cables.  I repaired everything fine, however I forgot to disconnect the internal battery!  As I was attaching the LCD cable to the motherboard, it wasn’t straight at first I could smell the dreaded burning plastic/electronics odor.  An obvious short occurred with the continuous voltage on the backlight traces. The LCD cable is visibly toast on the end where the backlight traces are.  I still had the old cable, so cleaned up the motherboard LCD connector and all the contacts appear intact.

I connected that and everything works including the LCD panel, except no backlight!   When I connect to an external display, it all works as well.   (Is there a way to see exactly which Pentium there is in on the motherboard without signing into the laptop.  It’s a customer laptop.)

It seems likely that I blew a fuse or fuses on the motherboard itself, but is there a possibility that I damaged the backlight in the display itself?  I would think the damage is likely in the motherboard.

My dilemma is should I replace the motherboard, or the LCD panel first? (Of if I could solder new fuses on if it’s obvious where they are and I can order them just as fast.)

Thanks for any help in advance!

Edit:

I’m adding a few additional photos of both sides of the motherboard as requested. Here are a few of the first visible side:

Here’s a photo showing the top case having damage for one hinge screw as well, so opening is fine, but closing, the motherboard itself will put a little force on the hinge closing:

Here’s some photos of the back side of the motherboard:

I took a macro (iPhone13 Pro Max) picture of the fuse F2:

Than I took a picture under a microscope:

There IS continuity across F2. So that’s likely not the issue?
