Audio is most likely mute due to no video. Check on the crt board for your video voltages for the guns. Should be least 180volts or better at socket pins KR, KG, and KB. If the voltage reads are low remove board from the crt and check again. this symptom is common on CTC157, 158, 166, and 167 rca chassis's and certain magnavox chassis's.
