revin cu o intrebare tv functioneaza ok dar in st-by ledul trece in rosu dar face blinking de 2 secunde rosu-stins,rosu-stins nu am mai intalnit o astfel de semnalizare de st-by

am intrat in service si am sters eroarea 8 care o afisa crezand ca poate din cauza aceasta dar tot la fel

nu este activat timer dar este ciudat ca in st-by am o tensiune fixa de 12v iar celelalte de 24v,12v,18v oscileaza in ritmul pulsatiei ledului am sa analizez mai bine sursa in manual service pe care il am sursa este pentru diagonala de 37 si 42 inch si nu corespunde
