It depends on how hard you fell on it.
Long ago a roommate brought me his 6" CRT tv AM-FM clock radio. The
only one I've ever seen. His father got mad at him and threw it at him.
The picture tube was fine but the circuit board was broken. I soldered
jumper wires across the leads that were broken, not at the break points
but from the places where components were soldered in closest to the
break points. About 15 pairs of them, but it worked afterwards. Most
were obvious but some a few were just little cracks. I think you could
solder straight the "wires", the traces, but you'd have to scrape off
the lacquer or whatever it's covered with.
