What to do if my Radio Shack Pro-60 display lights up but there is no sound?

If the display of your Radio Shack Scanner lights up, but you're not getting any sound, the issue might stem from several components. It could be a defective speaker or headphone jack, which would need replacement. Alternatively, the problem could lie within the audio amplifier circuit (IC306), IF amplifier (IC301), squelch control (VR301), AF pre-amp circuit (0307), audio mute switching circuit (0308), or the switching circuit (IC303), along with their associated circuits. In such cases, replacing the defective components is recommended.
