salutare stimabililoracest tv a intrat cu sursa defecta(o dioda din punte),sursa de 3,3v,si o diooda zenner de 9v care iesea din octocuplor,defecte.schimbat toate patru;B+ este 123v,am si 9v daca las iesirea din sursa de 3,3v in aer.daca o cuplez imi cade tensiunea de 9v la 2-3v,si implicit nu am cei 3,3v pt.proc.ledul nu de aprinde.m-am uitat si pe schema dar nu-mi dau seama ce consuma.caderea este destul de mare,dar nu se incalzeste nimic.o sugestie ar fi binevenita.

care frate .ca are nenumarate alimentari de 3,3v.oricum la sursacare am schimbat-o daca ii lads out in aer imi scoate 3,3.dar conform schemei,mai alimenteaza si altceva,si in aloc de 12v cat ar trebui sa fie pe bara de alimentare a sursei am doar 9v.am incercat cu o sursa de 12v externa sa-l fortez dar ,desi tensiunea nu mai cade,tot nu misca nimic.ledul clipeste daca ii dau din remote.daca e proc sse poate arunca la gunoi.mai sap ,dar sugestiile sunt binevenite.
