We have a 55" led TV from about 10 years ago. We bought it at a physical sears store. I replaced the power supply board maybe 5-6 years ago? Because the backlight stopped working. The current problem with it is that if it has been on in the past few hours she you try to turn it on again it takes 15-20 minutes to finally turn on. No amount of power cycling or fiddling fixes it, you just have to press the power button and wait. If you turn it on after it has been off all night, then it starts up fine. I really don't want to buy a new TV right now and I don't really want a smart TV anyway.
