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.
