tv daewoo nu porneste


Recommended Posts

Buna . Am un tv Daewoo sasiu cp 185 g , in prima faza nu pornea si ledul palpaia , am verificat finalul linii care era defect l-am inlocuit dar tot asa se manifesta si frecventa linii nu era in baza . Am verificat sursa pe bec -ok, tensiunea de 5 v era undeva la 3 v iar pe tuner sub 1 v . am decuplat tunerul si 5v este ok ,dar tot nu porneste si ledul nu mai palpaie . Am schimbat procesorul si incearca sa porneasca (apare impulsul sincro in baza ) de 4 ori si ramane in stand-by.Am schimbat memoria , tot asa .Am schimbat tunerul cu un uv1316 dar nimic .Va rog poate ma puteti ajuta cu un sfat . Va mltumesc !
