I got a cobra 29classic cb, little hours. i have no sound from the internal or external speaker. thanks
Set the squelch and knob to full counter-clockwise position. Turn the volume up to the 1/2 way point. Disconnect the external speaker plug from the jack. Disconnect any PA speaker plug from jack. Static / voices should be heard from internal speaker. If not disconnect the mic. Static / voices should be heard. If not, tune a different channel, sound should be heard. if not, look for indication of the radio stuck in transmit mode. If in transmit, there will be no sound until you can stop transmitting (hopefully while connected to a 50 ohm dummy load or suitable antenna - otherwise the final transistors may be blown). Reconnect accessories to determine problem component.
Good luck!
