A. Pin protect utama pin 38 terukur normal 0 volt titik protect :
- D616 protect B+115V akan protect jika B+115V drop disebabkan elco C609 100uf/160V turun kapasitas,transistor horisontal Q601 D2586 short
- D504 protect output vertikal,akan protect  jika ic 501 LA7837 short pin 12 ke pin 11,normal tegangan dipin 12/output vertikal +14.95V
- D608,D610 protect X-RAY/heater,akan protect jika elco C620 1uf/50V turun kapasitas
