Solved! model UN 60J6200AF (Samsung) tv would not power on after lighting storm. Could see that a fuse was blown (brown) so we replace

How to reset a tv after motherboard/main board was replaced. Or how to update software if it won’t turn on. Has power now

If the TV has more than one board you can't be sure that the main board was the problem. If the TV had a power supply board that would be the first one to try. More than one board could be bad as well.
