ONE POINT REPAIR GUIDE

NO SOUND

There is no sound output by DIGITAL AUDIO AMP DAMAGE, repair the set according
to the following guide.

5-2. BY DIGITAL AUDIO AMP DAMAGE (IN ALL FUNCTIONS)

5-2-1. Solution

Please check and replace IC701, IC702, IC703 on MAIN board.

5-2-2. How to troubleshoot (Countermeasure)

1) Check FL±, FR±, RL±, RR±, SW1±, & SW2± signals from IC602 to IC701, 702 & 703 each input
function.

If no signal, check if I2S audio signals are entered to IC602.

Refer to “I2S audio signal interface” on Item 5-1.
2) Check PVDD_48V.

If 48 V is abnormal, check the SMPS.

3) Check +12 for driving the gate of AMP IC.
a. All the powers are normal, but if +12 V is low, there is possible for AMP IC to be damaged.
b. Remove a ferrite bead among FB703, FB707 and FB713 one by one.
When removed a ferrite bead, if +12 V is recovered, the IC connected to it was damaged.
c. Replace the IC with a new one.
4) Check the impedance between SPK+ & GND and SPK- & GND.
a. If the impedance is 0

Ω

, the IC must be damaged.

b. After removing the heat sink, replace it with a new one.

Comments !!

If a AMP IC among three is damaged, “AMP_PDN” to R103 changes HIGH to LOW at regular intervals.
The sound is not output by AMP power down function.
