    Default Probleme pornire TV

    Am un tv Panasonic care uneori nu mai porneste din telecomanda. Unica rezolvare este sa il inchid de la buton si apoi sa il repornesc. Comanda spre el ajunge, pentru ca led-ul pilpiie. Facea asta destul de rar dar acum a inceput cam des. Uneori incepe sa tiuie in stand-by.

    Daca e cu tub catodic ai lipituri la piciorusele integratului "jungla" care se afla linga selector in ecranajul ala metalic.Daca tot il desfaci lipeste si integratul de vertical care este linga traful de linie.

    Condensatorii din sursa trebuie inlocuiti.Daca tiuie in standby s-ar putea sa fie si ala de pe puntea redresoare 200 micro /400 V sau cam asa ceva.
