These conditions can cause the TV to shutdown and the power LED to blink 6 times
SOS Detect Circuit Explanation (7)
1.
SC board defect
2.
A board defect
3.
Disconnection of C board and A board
4.
Wrong diagnostic by A board
The energy recovery circuit is monitored in the SC board.
If the middle point voltage is detected abnormal, the circuit generates the SOS6_SC1 signal causing
the unit shutdown and the power LED to blink 6 times.
