dragutzzz_112 Posted December 18, 2013 Share Posted December 18, 2013 am imaginea intr-un colt verde si intr-un colt mov. Iam schimbat PTC-ul iam schimbat si bobina de demacnetizare si tot la fel. Am dat si cu macnetul prin fata tubului si tot la fel... Ma puteti ajuta si pe mine in aceasta problema? Quote Link to comment Share on other sites More sharing options...
dan-a2 Posted December 18, 2013 Share Posted December 18, 2013 Se aude la pornirea la rece zgomotul specific demagnetizarii >> mai incearca si cu alt PTC. , daca nu merge posibil ca tv . sa fi luat o cazatura ,ceva si s0a descentrat masca t.k. !!

dragutzzz_112 Posted December 18, 2013 Author Share Posted December 18, 2013 la pornirea zgomotul specific demagnetizarii nu se aude. Am incercat si cu alt ptc. Am pus bec in locu la bobina 220v 60w si se aprinde becu Quote Link to comment Share on other sites More sharing options...
dan cod Posted December 18, 2013 Share Posted December 18, 2013 Curios.Poate e lovit sau foarte magnetizat si atunci ar trebui bobina externa. Quote Link to comment Share on other sites More sharing options...
Guest Posted December 18, 2013 Share Posted December 18, 2013 In serie cu bobina de demagnetizare aveti un termistor, verificati continuuitatea acestuia. Quote Link to comment Share on other sites More sharing options...
