Cum pot reduce dimensiunea verticala la acest tv?Initial,a fost defecta bobina de deflexie(spire in scurt la bobina pt. orizontal).Am schimbat blocul de bobine,dar din service nu reusesc sa ajustez dimensiunea pe verticala,pana la normal.Mentionez ca bobina actuala are cca. 14 ohm(in manualul service,de la ed.ELCO am gasit cca.10 ohm),deci difera de originala.IC este TDA8356,procesor SDA 5255-A017.Orice idee e binevenita,chiar si adresa unui magazin on-line,unde as gasi bloc original

Da,s-a rezolvat!Am modificat cele doua rezistente inseriate cu deflexia,si din service am reusit sa stabilesc dimensiunea normala.desigur , a trebuit "umblat" si la inelele de corectie de pe gat.Cu "service" am rezolvat relativ usor,ca aveam o telecomanda dezafectata,la care i-am facut modificarile necesare.Multumesc de idei. :drinkers:

Multumesc de idei. :drinkers:

Ideea era sa modifici tensiunea de reatie pe care o foloseste TDA3653 pt reglajul amplitudini curentului de iesire spre bobilnele verticale modificand rezistenta de pe care se culege aceasta tensiune .
