Sam's Samsung HD TV turns off after about 10 seconds. He's googled it and sees things from replacing the remote to replacing the motherboard in the TV altogether. Can he DIY it? Videos say he can. Leo says that today's modern flatscreens aren't very fixable at all. Even if they could repair it, it's likely going to cost more than the TV is worth. It's not like the old days when you can get a TV repairman out to fix it.
Leo suggests looking at a 4K OLED.
