TV LG26LG3000 cu imagine lipsa

Recommended Posts

Am un LG 26LG3000 la reparat.Sursa pare OK,dupa masuratori.Invertoarele sint si ele in regula(neoanele sint aprinse).Indiferent din ce sursa ii vine semnalul la intrare,citeodata(nu tot timpul),dispare semnalul prelucrat,sunet este,neoane aprinse.Comenzile le ia de la tlc,sursa nu pica:5v,12v stau foarte bine.Am cautat contacte slabe pe placa de baza,am refacut mai multe lipituri,tot asa se conporta.Nu se incalzeste nimic in exces.Vreo idee cam de unde ar fi cauza?
