Please avert your eyes when you see the terrible soldering job. I got impatient and tackled this with a sub-par 30w iron and no microscope, instead of waiting until I got to school today. The job is less than ideal. The pad also took with it a bit of the top layer to the left of it (and exposed some copper, but there is continuity to ground, so that doesn't help) so as you can see, I can't really drop some conductive paint in there. My only choice is really to find a series TX resistor, but I'm having some trouble. I've attached some pictures if you'd like to take a crack at it.
Thanks,

Those make it look like the traces go directly under the shield.
Amazon has been soldering those shields in-place for several models now.
Alright, if they want to be that way - what dissolves cured solder-mask?
Acetone? Maybe.
It does on my stuff, but I use a UV cure sm ink.
I haven't tried to wipe away the Amazon solder mask to expose the top traces.
And you had better wait until you get to school with access to a good re-work microscope.
They don't leave you a lot of working room there.
P.S: The on/off and reset connections on the PW-2 have been tested and found working.
P.P.S: When I wrote **bright** light, I meant it.
