Data pin protect:

Pin protect utama di pin 81 normal terukur 3.2V

Pin protect ac detector di pin 82 normal terukur 3.6v

Sensor protect ada di:

D603 jenis SMD heater pada + elco C603 4.7uf/50v normal terukur 20.1v jika elco ini kering maka tv akan terprotek.

D607 dan DZ608 ABL jika tegangan ABL naik, tv otomatis terprotek.

D203 +33V tuner jika zener +33v short tegangan +33v drop, maka tv akan terprotek.

D1005 +5V tuner

D1008 out ic 751 LM7805

D1002 ac detector di pin 7 travo acmatic, jika dioda ini short atau dilepas raster ada tapi display tak muncul, channel yg sudah tersimpan pun ikut hilang.

D503 ic vertikal normal terukur di katoda dioda ini 0.7v diambil dari tegangan pin 7 ic LA78040 normal tegangan di pin 7 2.3v jika ic vertikal rusak/short maka tv terprotek karena tak ada/hilangnya sinyal V sync.
