    Great TV for the price!
    The Toshiba 50 inch Smart 4K UHD is a great option if you are not looking at a pricey TV. I have this installed in my bedroom and probably use it around a couple of hours or less everyday. The first night I forgot to unplug the TV and since it was technically "off", I thought it would be ok. I woke up in the middle of the night to find that the TV was switched "on" and was showing the Home Screen. I switched it off (but did not unplug) and fell asleep when I next woke up in the wee hours of the morning, it was on and showing a blank screen and was unresponsive. I immediately unplugged it and when I plugged it back and switched it on again it worked perfect.So, now I make it a point to unplug the TV when its not in use, or better yet, if you have a switch that turns off power to the TV, use that.The sound is absolutely great! I hardly have to go above a setting of 14 or 15. The picture quality is not that good and while the 4K and UHD rendering may be happening, I find my 2011 Samsung Smart TV (6000 series) to have better picture quality than this one. I would certainly not have this TV as my living room TV. Its good enough for a bed room or maybe even a computer monitor. The WiFi works great and never drops. I like the Amazon Silk Browser, which allows streaming of web content. I could not get Kodi to run on this despite installing it, maybe there will be some changes to this in future. Other than that, Netflix, Amazon Prime etc runs smoothly on it.

    I remember getting my first LCD monitor in the late 90s for well over $600, and it was 15". This is a 50" smart TV, with 4K, for half that price. What a time to be alive!

    The TV was packaged very well and I was surprised how light it was, just moving the box down to the home gym I've been piecing together. Getting it setup on the stand was downright simple, and after a couple of software updates I was ready to rock. The picture quality was as good as I expected for the price, possibly a bit better. The on-screen menus were easy to use, the remote works well, and the total startup time for the TV is just a few seconds from sleep mode.

    I was especially impressed by the built-in FireTV. Full disclosure: I've worked for Amazon for about a decade now and I've been a bit fanatical about the FireTV products since they were first announced, and the built-in FireTV experience feels a lot better and responsive than any of the dedicated FireTV products I've used so far. It's fast, responsive, and integrates TV/channel functionality right into the menus.

    The sound quality of the TV is also a little better than I expected for the price. I can hear it loud and clear while on the elliptical. It's not going to blow your mind like, say, an IMAX experience, but it will probably surprise you how much sound you get out of a relatively cheap TV. The built-in sound may actually sound slightly better than my LG OLED (if I bypass the sound system and actually use the built-in speakers like some sort of ... barbarian).

    I was skeptical, but no longer. I'm considering replacing my ollllld 32" in my bedroom with a newer model in the near future and might look to one of these again!

    5.0 out of 5 stars Great value for those ready to upgrade to 4k.
    Reviewed in the United States on July 29, 2020

    Just got this TV today (7-28-20) and overall I am very pleased. The picture and sound quality are really good. It functions like a 4k fire tv stick but you can connect it with an ethernet cable. The only things I don't like about it so far is that you can't set up a speaker pair with your echo speakers like you can with the 4k fire tv stick. The remote is also very limited. Although the quick app launch buttons (Prime Video, Netflix, Hulu, and HBO) can put you straight into those apps even when the TV is off, just by using those buttons instead of the power button. Adjusting the picture required me to go back to the home screen then use the settings button on the remote, which was a little annoying, but after I was done settings everything up wasn't a big deal. I picked up this 50 inch 4k TV for $300 so I still feel the overall value for the money was well worth it. -UPDATE- (8-20-20) I realized my issue with the picture settings was that I just wasn't pressing the settings button long enough. A quick tap will not bring up the settings, but if you hold the button down for a second it comes right up as it should. Another feature that I like is when you are on the home screen and you highlight an input (which you can name) it will show you a real-time picture/ video of what that input is currently displaying in the top right corner of the screen. 5 Stars all day!!! A great 4k 50 inch TV with Fire TV built in for $300. It's a no brainer!!!

    This is a late review in coming. I bought my Toshiba in August 2020. It’s now March 2024 not quite four years and the TV just stopped working when I look up troubleshooting the information I am getting is that is the motherboard, which is a very expensive fix so it’s going to curb.
