Problema LA7830

Recommended Posts

Buna seara . Intr-un televizor Sanyo model CEM 2130 cadrele sint cu LA7830 . Acest integrat lucreaza la temperatura de 64 de grade , intrebarea mea este daca e normal sa aiba temperatura aceasta ( cu toate ca am schimbat elco-urile de filtrare a tensiunii de alimentare si cel dintre doi pini de integrat si daca nu e normal , ce ar putea cauza incalzirea lui . Multumesc .P.S. Tensiunea de alimentare masurata al integratului este 24 V , radiatorul este din aluminiu cu suprafata apr. de 25 cm patrati .
