These conditions can cause the TV to shutdown and the power LED to blink 8 times
1. Failure of SS board
2. Disconnection of SS (SS2) board and Panel
3. Disconnection of C board and A board
4. Disconnection of SC board and A board
SS
SC
IC16921
The IC9300 monitors the UHZ signal via IC5000.
if the connection of SC and A board is disconnected, the IC9300 doesn't output the control signal of
SS. Consequently, the SS board detects error and generates the SOS8_SS causing the unit
shutdown and the power LED to blink 8 times.
