I reset the breaker and turned everything back on without a problem - except the Samsung which will not respond. I checked the plug the TV is using and the power is fine, but TV will not turn on using any of the remotes.
So, is there an internal fuse? Anything else to check? Thanks!
Given everything you've described, I would expect that something inside the TV shorted out, and the rush of too much current blew the breaker as well as the fuse inside the TV. I would also expect that when you take the back off, you'll find the fuse blown, as well as possibly seeing evidence of damage to a board, possibly the power supply. And when you replace the fuse and turn it back on, the breaker will blow again.
Alternatively, the fuse might be intact, which would indicate that something downstream from the fuse self-destructed and opened the short circuit that originally blew the breaker.
If it's the power supply, that might be good news, since the last time I looked those seemed to be available on eBay.
If there's no evidence of damage inside, diagnosing it will get tricky for us amateurs, and if it's something like the Y-board, finding a part to fix it could be a challenge.
But given the sequence of events reported, I would really expect that a short circuit happened inside the TV.
