am un tv cu sasiu 11ak19B1 si are probleme cu e-w.am gasit mos-ul intrerupt(buk444) iar dupa inlocuire acesta se supraincalzeste imediat, urmand sa se deterioreze din nou.Am verificat componentele din jurul mos-ului dar nu am gasit nimic deosebit...daca are cineva vreo sugestie, ar fi binevenita :prayer:
