Va salut cu stima ,va rog daca cineva ma poate ajuta cu o schema electrica sau cu un sfat.

Am un PNI ESCORT HP-9001 ,de cateva zile nu mai am sunet ,am verificat difuzor ,mufa ,integrat audio (nu am schema dar trebuie sa fie TDA2003) si nimic ,sunetul se aude in transformator daca dau volumul la maxim si integratul de sunet se incalzeste.

Am demontat si transformatorul si nu se mai aude ,de masurat (are 4 fire dar doua din ele este ca si cum sunt doua infasurari paralele) intre toate cele patru fire da cam aceeasi valoare ohmica ,undeva la vreo 0,3ohm)

Va rog daca puteti sa-mi dati un sfat ,ce pot face.

Multumesc anticipat
