Troubleshooting 7 Blinks Error Code

The SC board has 2 SOS detect circuits, energy recovery and floating ground section.
When the energy recovery circuit is triggered, the TV shuts down and the power LED blinks 6 times.
The floating ground circuit monitors the scan circuit output, the 15V_F, the scan_pro, Vscan, and the
physical connection between the SC board and the SU/SD board (CHA).
If any abnormality occurs on any of these lines or Vsus is missing, the TV shuts down and the power
LED blinks 7 times. If any of the connectors between the SC and the SU/SD board is open, the TV also
shuts down and the power LED blinks 7 times.
SC – 80%, SU/SD – 60% Probability, DA – 20% Probability, P – 20% Probability
