I have a Samsung TV UA40F5000AR that doesn't turn on but has the red light on.
When I checked the internet, the problem seems to be either in the main board or the power supply board.
The technician came and thought the problem was in the main board, so he replaced it with a new one. The TV turned on, so he turned it off and closed the back cover and returned it to its place (since it was fixed) but when he tried to turn it on once again, it didn't.
He said that the problem is in the power supply board, and it burnt/totally damaged the new main board.
So my question is... Is this be true? Can the power supply board totally damage a new main board within few seconds?
