Buna ziua.Nu mai deschid alt topic fiind vorba exact de acelasi sasiu TNP 8EE007, cu defect tot in sursa-tv-ul a fost supus supratensiunii si a crapat c807-100micro/400v. Dupa inlocuire led-ul se aprinde pt. o secunda dupa care releul se declanseaza, iar led-ul palpaie intermitent, iar pe C 807 nu exista 300volti. Credeti ca a fost afectat si STR-ul? Va rog dati-mi niste idei.cu stima!
