7 Blinks Error Code
1. VAD or VSCN circuit defect
2. Disconnection of SC and SU/SD board
3. F5V / F15V abnormal voltage
4. VAD / VSCN abnormal voltage
These conditions can cause the TV to shutdown and the power LED to blink 7 times
5.SOS Detect Circuit Explanation (9)
The VAD and VSCN circuits are monitored in the SC(SN) board.
If these circuits don’t work normally, the SOS circuit generates the SOS7_SC2 signal causing the
unit shutdown and the power LED to blink 7 times.
