Buna ziua.Am si eu un osciloscop made in china si a inceput sa-mi faca figuri mai exact:Dunga orizontala este intrerupta iar semnalul, o sinusoida de exemplu o arata pe alocuri zimtata.Stiti cumva ce poate sau de unde ar putea fi?Cu multumiri anticipate.

Daca facem o analogie cu TV-urile CRT, miroase a trafo de HT in curs de strapungere sau in cazul cel mai fericit un electrolitic uscat (cel de pe primarul sursei in comutatie).Verifica electroliticii din sursa si poate ai bafta sa gasesti unul umflat!Succes.
