1 2 3 4 Symptom: No sound from the cordless headphones A Connect the AC adaptor while holding the POWER switch and the ProLogic II switch of the transmitter pressed. (Noise simulation mode) START B Is sound output from the headphone terminal of the transmitter? No Yes C Is the IR-LED-drive waveform normal? (TP11-TP13) No D Yes Check the headphones. Check the transmitter.
5 6 7 8 Symptoms: Failure in sound and indication of the transmitter (Checking the transmitter) A Connect the AC adaptor while holding the POWER switch and the INPUT switch of the transmitter pressed. START Did all the LEDs light up in order? No Check the power source (AVCC). Check the peripheries of the LED drive TR and of microcomputer (IC4). B Yes Disconnect the AC adaptor. Connect the AC adaptor while holding the POWER switch and the ProLogic II switch of the transmitter pressed.
1 2 3 4 A Connect a player (DIGITAL 1, DIGITAL 2, and analog). POWER ON B No Is sound output? Check the peripheries of IC5 and IC1. Switch to DIGITAL 2. No Is sound output? C Yes Check the peripheries of IC13 and JA3. Switch to analog input. D No Is sound output? Check the peripheries of A/D (IC7), IC6 and JA1. Yes No After three minutes or more of continuous playback, does the IR LED remain lit? E Checking audio detection Check the peripheries of IC9 and Q1.
5 6 7 8 Symptoms: Failure in sound and indication of the cordless headphones (Checking the headphones) A START Insert the battery and set the Power switch to ON. No Does the LED light up? Check the Power Board Assy, lead wires, and the peripheries of Q1 and D1. B Yes C Is each voltage (VCC, A1.5 V, D1.5 V, A2.5 V, D2.5 V, and DAC2.5 V) OK? No Check the Power Board Assy, the peripheries of IC7, IC8, and IC9, and the periphery of Q1.
