What to do if sound doesn't occur from RY921 on the MAIN board when inserting/removing headphones on my Sony Receiver?
If sound doesn't occur from RY921 on the MAIN board when inserting and removing headphones, check the surrounding circuit of the power transistor (example: Q600 on the MAIN board) and the surrounding circuit of the power amplifier circuit (example: FL on the MAIN board). Exchange any defective parts that you find.
