John, right of the bat, you are missing at least three components. Two capacitors and 1 inductor:

C93 RF 1.0PF +/- 0.1PF 25V C0G 201

L17_RF 4.3NH+/-0.2NH (Little blue coil)

C95_RF 1.0PF +/- 0.1PF 25V C0G 201

The reason why you can get away with just bridging the inductor is because it is in series with the trace. Both caps need to be going from that same trace the inductor is on to ground. I attached the schematic for that as well. Zoom into the picture to visualize it more directly. The problem with this now is a:are your trance still okay and B; somebody with the right tools and the right skills need to do the soldering. It appears that this is what caused the issues in the first place. The parts are not expensive and are readily available at most electronic warehouses like Mouser.com or Digikey.com. Depends on where you are located.

John, I would be more than happy to help you out, but it probably cost you more in shipping than having it done somewhere in Portugal. Thank you for accepting my answer.
