Sasiu TV17.6.Tv-ul s-a defectat dupa 5 min de la pornire.Condensator c309 explodat rezistenta R302 scrum,altceva nu era vizibil afectat.Schimbat piese busite,masurat, sapat dupa alte busituri...nimic.L-am pornit si pleaca dar nu are imagine.Am marit G2 si intr-adevar nu vad decat un rastru luminos si cursa inversa.Tensiunile par ok.Va rog o shema completa si ceva sfaturi.Multumesc!

Da ca in fotografie.Am verificat placa si nu pare sa aiba cablaje arse.Am masurat chiar si diodele si tranzistorii smd si e ok.

Am sapat de mi-au sarit capacele.Cred ca problema e din modulul digital pentru ca din schema rezulta ca bara HFLB pe care a fost problema ajunge cumva direct in pinul 8 al procesorului video si cum in afara de rezistenta scrum nu am gasit altceva....Problema e de unde gasesc eu un modul digital vga de sasiu tv17.6 sa-i fac o proba.
