My Samsung 58" TV got some water in the back that appeared to drip in from overhead. I was unaware of this when I turned on the TV. It powered up but had a loud buzzing noise and eventually a pop/spark in the back before the picture went out. I've since unplugged the TV and removed the back. I don't believe much water was in it and dried what I could see visually. It did appear there was a small burn mark on one of the green circuit boards. Now when I turn on the TV it doesn't buzz, the screen flashes initially, but doesn't appear to have any picture. I also smell a faint burning smell. Is this something that can be repaired or is the TV permanently dead?
