Guest scarstoi Posted February 13, 2014 Share Posted February 13, 2014 Va rog sa ma jutati la rezolvrea urmatorului defect:Ledul de st-by (culoare rosie) sta continuu aprins. Tv are incercari esuate de start.In secundar tensiunea U1 este crescuta (am masuta-o si este de 170 V iar in schema este data ca fiind 110 V). Transformatorul chopper are tiuit putenic.Pe placa tv nu este nici un condensator umflat.Multumesc anticipat pentru sprijin. Quote Link to comment Share on other sites More sharing options...
