  If your JVC Stereo System exhibits no sound or weak sound (low sensitivity), it could be due to several reasons: * A defect in IF T101, T102, or T103: Check the resistance, voltage, and current. Replace as needed. * A defect in the AM antenna coil T106 or oscilloscope coil T104: Replace if necessary. * Intermediate frequency tuning faulty: Readjust the tuning. * RF tracking faulty: Readjust the RF tracking. * Defective IC101: Check the voltages and replace if necessary.
