TV Philips 28CE5597

Recommended Posts

Am un TV Philips model 28CE5597/02B care a intrat in stand-by din mers(nu era nimeni de fata) si asa a ramas. Nu porneste nici din butonul oprit-pornit nici din telecomanda.Am masurat in sursa si nu am gasit nimic defect.Am simulat sursa de 7v realizata cu tiristorul 6727 ,asigurand tensiunea din sursa externa si aparatul a pornit( a aparut FIT,blocat video, fara afisare de program pe digiti), de notat ca tensiunile din sursa sunt cele din schema.Orice sfat sau idee este binevenita.
