Salut dragi colegi....lucrez la un tv cu placa 11ak19b1 care parea ca este in stend-by cu ledul rosu aprins dar lumineaza doar la jumatate de valoare.... am dat tranzistorul final afara si am pus bec, sa verificat condensatorii, diodele tensiuni in stend-by dar nu pornea si am scos memoria..... surpriza... a pornit are rastru dar nu si imagine. Daca ating pinii selectorului are ceva imagine pe diferite canale chiar color dar sunetul are valoare de minim chiar daca al maresc. Am pus alta memorie si nu porneste dar porneste daca o scot ........dati-mi macar o idee.
