Judgment of the Panel SOS Signal for TC-P**ST60

5.SOS Detect Circuit Explanation (5)

TC-P**ST60 Series (All models)

These are illustrations taking from a normally working Plasma TV.
IC8000 checks the panel SOS signal for abnormalities at exactly 800ms 
after the TV is turned on.)
IC8000 ignores the first 720ms period of the panel SOS signal, which starts 
after the TV is turned on (Starting point). Judgment begin at 800ms and 
after the starting point.
