    Kemungkian besar flybacknya memang rusak, (bocor)
    Coba diganti saja dulu bos, mudah2an kembali normal tvnya
    (Untuk jaga2, sebelum flaybacknya dibuka (tutup yg di tabung), agar digroundkan dulu)

    .......lepas voltase yg masuk flayback dulu coba ukur ada voltasenya gak ...kalau ada berarti regulator normal ...bunyi cit biasanya voltase output regulator ada yg ngedrop ...kalau gak flayback biasanya output flayback tr horisontal yg short/mati ...

    kalo menurut saya,bunyi pletek2 di sebabkan oleh flyback yg bocor(bisa di kabel anoda atau di body flyback)shg menyebabkan TR horz rusak..dan untuk bunyi cit2 disebabkan karna shortnya TR HORIZONTAL( colektor dgn emitor)...smoga membantu
