Helpful to know where you're located and what you're prepared to spend on restoring its operation.
There are probably quite a few on this forum that can do such a task (I can) and your local amateur radio fraternity would probably throw up someone who would do it for the kicks rather than a handout - no guarantees though.
You could even fix it yourself! Try posting pics, a schematic and any details of the actual fault and we could, at the very least, indicate whether or not this is a cost-effective procedure or that you're wasting time even trying.
