I have a Philippine made Cobra 29 that developed a problem yesterday - no sound. When I plug an external speaker into the pa jack and switch the radio to pa I hear radio transmissions, otherwise there is no sound at all. I would appreciate your thoughts on what the problem might be. I live in northern California (Sacramento area) and would also appreciate any thoughts on where to take it for repair. I've had this radio a long time really like it so I would prefer to repair rather than replace it.
