What is this Hp b23 010 motherboard

This is actually the 23 AIO model but both use basically the same motherboard I believe, originally there was a white almost looked like a jumper over this. My screen would flicker and eventually went completely off but if you toggled that jumper it would come back on. Almost like a short within it somewhere. I know the whole system might be worth 10 bucks on a good day but it’s suitable for its job and it has touchscreen which makes it convenient also. Basically my question is it worth ordering and soldering that back and what is it called and purpose. Thank you first time ever doing this so please be kind I know there’s a lot not to be within it. Thanks.
