CONGRATS @TS SCOT......
DIODE talaga yan, buo siya pag na tester mo siya maski naka hang up.... sa analog tester, pag sinukat mo ang voltahe ay hindi mo mapapansin na babagsak ang voltahe mo pagtawid ng ANODE niya ( o CATHODE ba yun), pero if you are using a digital tester, BE AWARE sa voltage drop niya, dapat 14VDC siya, pagtawid niya sa kabilang side e below 13VDC  siya, minsan 10 Vdc na lang...

May Tama ka sir kasi nawawala yung +14VDc sa internal power amplifier ckt nung STV9302 twing magloloko yung Rectifier. I'll post yung schematic ng Vertical ckt and also yung internal ckt blk diagram nung STV9302 later para maliwanag..^__^

Again Thank ulit sa mga Masters specially kay SisEnriz622. ^__^
