Recommended Posts

Salutare...mi-a venit un tv Crown la reparat, model CTV5616, jungla TDA8361, la care am gasit ars BUZ-ul din sursa...l-am schimbat, tv afea ciuperca de la FIT impuscata...am schimbat-o /spalat cu alcool (posibil sa-l fi folosit in condens).Tv porneste de la buton normal, de la P+, apoi cand incerc sa-i dau P+ sau -, sau volum acesta nu ia comenzile...daca tin tasta apasata mai mult incepe sa le ia...tensiunea pe procesor este 5V1 masurata cu osciloscopul...rog un mic ajutor

Curatati contactele de la taste sau de la telecomanda. Eu le curatam cu spirt. Folositi baterii noi. Eventual, daca are microswitch-uri, inlocuiti-le si pe alea, poate au oxidat.
