Recntly my Tv went down as I was watching and all I could hear was a buzzing sound coming from one of the componets on the board. When I tried to troubleshoot, I mistakenly burnt the STR ic and a capacitor and also foundout before that the transistor the connects to the high voltage supply was burnt. When I replaced the STR and transistor, the screen powered but immidiatly the screen went blnak and buzzing sound came back. Could anyone help me out on what to do?:confused:
