( 1 ) Transmitting and receiving check.
YES
NO
NO
YES
Is the module FFC loose ?
No sound is produced at the subwoofer.
( 2 ) Audio does not operate normally
1. When unable to “pair” or “link” between the sound bar unit and subwoofer.
Is the TX and RX module supply + UN_SW5V ok?
1.
Is the communication signal ( I
2
C ) ok ?
(Fig. 1 - During AUDIO IN function)
(Fig. 2a & 2b - During HDMI 1 / 2 function)
2.
NO
Is the module FFC loose ?
Is the Tx and Rx module supply + UN_SW5V ok?
1.
Is the communication signal ( I
2
S ) ok ?
(Figure 3a and 3b - for normal operation)
Check :
Tx - CNP502  Pin no. 13, 14 and 17.
Rx - CNP600X  Pin no. 22, 23.
2.
NOTE : All waveforms are tapped from CNP502 (MAIN / AMPLIFIER PWB-A1)
Check incoming supply. 
(Rx - CNP600X Pin no. 1 and 2)
