Lets hope its a loose or disconnected wire. If it's not it is possible you have a hair line crack in the board, which is a pain to fix.
Check all the wires going to the front panel of the radio. Pay close attention to the wires that go to the switch for CB/PA mode. If one of the wires comes disconnected, then it may be stuck in limbo between PA mode and CB mode.
If there are no loose wires, and there is a break in the board, then the only way to fix it is to find what traces are broke and solder jumpers past the breaks. It's a bit of work to find all the problem points.
Also, Inspect all the solder joints on the trace side of the board for cold solder joints. I would go over them and make sure all of the solder points are fully soldered.
