tv seg ct2501 defect de imagine


Recommended Posts

Am verificat circuitul de demagnetizare si functioneaza corect .Demagnetizarea am reusit sa o fac cu ajutorul unei bobine de demagnetizare cu diametrul de 30 cm confectionata din sarma emailata de cu d 08 mm ,nu mai stiu cate spire are bobina .Tv a functionat corect ,dar dupa o zi de functionare fenomenul a reaparut .Mentionez ca nu sant obiecte metalice in preajma tv .Pute ti sa mi spune ti ce ar mai putea fi ? Multumesc!

Va multumesc pentru indicatiile date ! S a rezolvat problema ,Tv ul statea intr un cadru construit din rigips ,care era prins de corniere metalice si cred ca circuitul de demagnetizare nu reusea demagnetizarea completa .Dupa schimbarea locului tv ul functioneaza normal .(Foarte curios!)
