6 Blinks Error Code Circuit Explanation

The sustain drive circuit on the sustain board is not a complete circuit. There is a part of this circuit in the SC board.

The cable between connector SS3 on the sustain board and SC3 on the scan board links these 2 circuits

The section of the sustain drive circuit located on the scan board uses Vsus for complete operation of the sustain output circuit.

The energy recovery circuit in the SC board uses a comparator (Error detect IC16581) to monitor the operation of the scan and sustain output circuits . The output voltage is compared to 2 reference voltages derived from the P15V.

If the output of this circuit drops below 5.2 or goes above 11.8V, the output of the comparator IC6581 goes high to trigger the “Energy Recovery” SOS line. This high is provided to the Panel CPU on the A board. The TV shuts down and the power LED blinks 6 times.
