6 Blinks Error Code
The Scan and Sustain voltages on the SC and SS boards are monitored by an SOS Detect circuit.
The energy recovery circuit in the SC board is monitored by a comparator (Error detect IC16581). 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.
SC – 95%, DA – 50% Probability, P – 20% Probability, Connections between DA and Cs - 30%
