ciuca paul Posted March 13, 2015 Share Posted March 13, 2015 Salutare tuturor.La acest tv am o problema ciudata ,manifestandu-se prin trecerea tv-ului in stan-by aproape in mod aleatoriu ,la schimbarea programelor dar indeosebi prin folosirea meniului atat din telecomanda cat si din manual.Din masuratori n-am constatat nimic anormal tens. de 3,3 si respectiv 5v in stan-by sunt corecte dar si in functionare corecta cealalta tens. de 5v este stabila. Multifunct. este de tipul tda11105ps/v3/3 si pe pinul 38 acesta comuta inexplicabil tens. de std-by .Am pus o memorie goala dar fara rezultat.Daca nu-l deranjez din comenzi fenomenul se repeta mai rar .Am verif. si filtrajele , cantacte imperf. dar nici o schimbare,va rog sa-mi dati ceva sugestii ca am intrat in criza de idei..

geoky Posted November 26, 2015 Share Posted November 26, 2015 (edited) Salutare domnilor, Am Buntz-ul cu chss din titlu, a venit cu imagine normala lipsa sunet, celebrul condensator C564 de 1000/16V umflat, l-am inlocuit, (facut proba=tv functioneaza corect) am inlocuit si alti condensatori devalorizati, refacut lipituri reci si am pus tv la probe, stupoare,nu mai starta. Am revizuit organoleptic placa, mi-am dat seama ca am facut un scurt la lipituri, ca am iesit din tura de noapte si nu am dormit. Asa era, scurt circuit intre baza si col la trz V592, apoi am mai gasit dioda zenner VD561 scurt ca efect la scurtul provocat de mine. Vin si va intreb daca stie cineva de cat este zenner-ul asta, ca am cautat si nu gasesc nimic asemanator, o schema ceva ... multumesc Edited November 26, 2015 by geoky Quote Link to comment Share on other sites More sharing options...

geoky Posted November 26, 2015 Share Posted November 26, 2015 sursa este clasica, dar are multe stabilizatoare 3v3, 5v, 8v, 12v numai cu tranzistoare si inghesuita rau, vopsea si dungi pe la terminalele pieselor de nu vezi traseele ... si cand lucrezi sub stres, iti vine sa-ti iei campii ...uf ! am rezolvat-o, dioda era de 12v, nu aveam la multifunctional 5v si 8 v Quote Link to comment Share on other sites More sharing options...
