Battery corroded numpad

[lyk93]

Hi all,

I'm new to repairing electronic
I got this Logitech n305 numpad that was corroded by battery acid.

I cleaned it up but it is still not powering up. So I took it but I cannot really spot the problem.

I hope I can get some help here.
I've attached some photos of the corroded parts since the rest of the circuit seems fine

It is classic case of eaten traces under mask (second picture)...
Check continuity and if fail, you have to replace it or to use few jumper wires.

Hi I have tested for continuity and it seems that there is continuity but when I put in batteries there is no power

Is there any other solutions?
Thank you
