    coba tegangan b+ yang masuk ke FBT dilepas dulu.jika normal 115v periksa transistor output horisontal biasanya suka rusak. klo transistor ok berarti FBT gak normal bos. mohon koreksi :peace:

    trimkasih Gan, permslhanya sdh ktmu teryata ada resistor digital yg ptus didket ic TEA nya, jd walau pun ic diganti berapa kali bakal rusak lg, stlah dignti R nya trus ganti IC Lg alhamdulillah tegangan normal. Terimaksh
