If you still have the old broken one, see if you can remove the plastic cover then check continuity from each connecting pin through the circuit to the device mounted on the ceramic. My fault was no DC to one of the devices. Bridge it and you should be back in business. However it is not easy to solder to a track on the ceramic because it conducts away the heat from the soldering iron quite a bit but it can be done. 73
