Defect TV Philips

Recommended Posts

Este vorba de un TV Philips , model 26PFL3403/10 , sasiu TCM2.0E AA.Problema : led rosu aprins , nu pleaca din stby.La comanda ON din TLC sau din buton , se aude cupland releul si , ori se stinge Ledul , ori ramane aprins rosu ,dar TVul nu porneste.Dupa deconectari de la reta porneste din buton sau TLC si functioneaza corect.Porniri /opriri succesive ulterioare din TLC ,OK.Tensiuni masurate , OK , filtraje verificate , ok , schema exista , mai putin partea de sursa.Necazul este ca sursa - invertor nu are nici un cod marcat pe placa.Are cineva in lucru , a avut o astfel de belea , sau o schema pentru sursa asta ?Multumiri anticipate !

Dupa stiinta mea TV_ul asta are o sursa secundara pe care intradevar exista un releu.Din cate stiu , sursa asta functie de model ,este optionala .Vezi daca ai asa ceva in tv (plasata in dreapa jos) si daca da , nu strica sa verifici daca se stabileste contactul releului pentru alimentarea sursei mari.Releul are bobina la 5V si contactele destul de solicitate.Uite si ... sursa :
