Toni Marginean Posted October 14, 2012 Share Posted October 14, 2012 Intra in calcul doar doar doua posibile defecte: circuitul de demagnetizare sau tubul. Quote Link to comment Share on other sites More sharing options...

dan cod Posted October 14, 2012 Share Posted October 14, 2012 Daca pubeai o poza era mai clar pentru noi.A cazut cumva tvul sau a fost lovit? Quote Link to comment Share on other sites More sharing options...
kog1 Posted October 17, 2012 Author Share Posted October 17, 2012 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! Quote Link to comment Share on other sites More sharing options...

dan cod Posted October 17, 2012 Share Posted October 17, 2012 Nici ceva boxe sau alte aparate nu ai in zona?E perete comun cumva?zona unde ai tvul? Quote Link to comment Share on other sites More sharing options...
kog1 Posted October 22, 2012 Author Share Posted October 22, 2012 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!)
