These conditions can cause the TV to shutdown and the power LED to blink 6 times
5.SOS Detect Circuit Explanation (7)
1. SC board defect
2. A board defect
3. Wrong diagnostic by A board
The energy recovery (MID) voltage is monitored in the SC(SN) board.
If the MID voltage is detected abnormal (under 50V), the circuit generates the SOS6_SC1 signal
causing the unit shutdown and the power LED to blink 6 times.
