Acest Tv este echipat cu sasiul  CP885F.Din pacate nu detin schema ascestui tv si nici n-am dat de ea,are probleme cu sursa am schimbat cei doi condensatori din primar cel de 47 uf si de1o uf,pleaca ledul pe verde la pornire ,dupa care se face rosu,iarasi verde iarasi rosu si tot asa .Variaza destul de lent intre 115Vcc si 20Vcc tensiunea de 140Vcc,am schimbat si SE si nici o schimbare,face la fel si fara finalul lini si in gol si cu becul ca sarcina.Cu becul se aprinde de11 ori dupa care ramine in st-by ,ledul este rosu dar ,se tot intrerupe intensitatea ledului si nu mai trece in verde.Orice idee sau parere ar putea fi binevenita .Va multumesc!

S-a rezolvat,defect datorat stabilizatorului de 5Vcc I820,nu mai scotea decit 3.8-4 Vcc atit masuram pe el si cadea sursa iarasi,cel putin atit reuseam sa masor,m-am tot invirtit pe linga processor pentru ca se tot reseta si dadea comanda de oprire a sursei in st-by,pe urma iarasi pornea si tot asa.Am pus un radiator acestui stabilizator,pentru ca am impresia ca se cam incalzeste,si acesta a fost motivul distrugeri lui.Va multumesc inca odata pt schema ,fara ea nu cred ca-l reparam.
