Am la reparat acest tv la care am gasit explodati c612,c613 intrerupte r619,r620,scurt ic601,explodat an15524.Sasiu este 11ak56.Am montat bec in c tr final linii si am 114v si toate tensiunile alimentare sunt bune,procesorul primeste tens de 3,3v pin 66.La pornire tv ledul ramane rosu si nu pornesc liniile.Am pus surubelnita pe cuart fara rezultat.Procesorul in faza initiala primeste doar 3,3v si dupa ce porneste si liniile primeste si 8v?

cu ce porniti tv-ul?cautati o telecomanda buna ca din bord s-ar putea`sa fie blocat si bateti pasul pe loc.cand se face led-ul verde apare tensiunea de 8v necesara junglei.led-ul este bicolor si in st-by este alimentat cu 5v si lumineaza rosu iar in on se alimenteaza cu 8v si lumineaza verde.
