Amusing... I'm still limping along a 45" Visio I bought back in early 2009 to watch the Superbowl. I then installed a digital antenna in my attic. The antenna stopped working a few years ago. The audio on the TV crapped out a couple of years ago, so I finally replaced the stereo system I've had since 1988 with a Sony A/V receiver...
I pretty much only use the TV as an HDMI monitor from my laptop, which is what I use for streaming YouTube and other services. I used to plug it directly into the TV, but now have to go through the receiver first. I also have a bluray DVD player connected to the receiver, although it's rarely used. I've tried using the streaming browser on the TV but it is so effing clunky to use that I prefer to use the computer. Someday I'll replace the laptop with a mini-PC and a wireless keyboard & mouse.
A bit of a luddite set-up, but it works for me.
