Un salut calduros Am o mica mare problema:acest tv cu placaT2S08,procesor de comenzi ST92195C7B1/MTH,STV2248 si BV cu STV9306 a avut o problema in sursa(Q611)in urma careia mi-a distrus finalul linii si condensatoarele de filtraj inclusiv pe 12V.Am remediat problema dar la pornire imi intra direct in "service"iar baleiajul vertical este instabil:ba este16/9,ba se mareste peste masura cu intoarcere si sfarseste cu linie orizontala.Am schimbat procesorul de comenzi fara sa se modifice problema,sa fie defect STV9306?Am reusit intr-o perioada de stabilitate mai mare sa-l programez din Service dar nu s-a memorat.Am fortat si resetare in timpul functionarii fara rezultat.Unde naiba ar mai trebui sa ma joc?Multam!
