    Gift to myself
    I had been wanting to buy a new TV for a long time. What prompted this purchase was me getting ready for back surgery. I knew I'd be spending a lot of time in my recliner, watching TV and high on pain pills. If I was going to be stuck in the house, I wanted a big TV. I upgraded from an old 50 inch that was probably 10 yrs old. This TV has a beautiful picture. I don't use the speakers. I have a sound bar that is amazing, so I'm sorry for not being able to talk about that. It has taken me a bit to adjust to the Amazon fire setup. I hade a roku setup on my last TV. But, after a couple weeks, I've gotten used to it. In all, I love TCL. My 32" TV in my office is a TCL and is great. I'm loving the 4K picture

      Bought this to replace a 50" vizio smart tv that picture was failing on. Love the fire tv and the included alexa. Color is great and setup was a breeze. Some said the build felt cheap to them - guess I DON'T know the difference in cheap plastic and good plastic - besides I really don't sit around feeling the build quality.

      Price was really good and features are good. The remote is user friendly as is the os. I REALLY DO RECOMEND THIS TV.

      Had a small problem with the sound on one channel which was odd as all other channels were fine. Called their help line and customer service walked me thru a very easy fix. Still a 5 star and will include customer service in the rating.

      HAVE had this TCL TV for one month and I find it better than our 65" SONY, better picture, color, sharpness just better all the way around. The one thing it lacks is a lot of color adjustments, but out of the box it really didn't need any and if I could adjust the settings I would probably screw it up. Just buy it! UPDATE: 3 months and still very satisfied with the purchase. I did notice that one person had trouble with the optical port in hooking up his sound bar. The best way to hook up the sound bar is to use the HDMI e arc port and it works great. I have never tried the on board speakers as I am extremely satisfied with the sound bar. Will update in six months. UPDATE; Small problem due to internet going down for close to a day. When it came back on I had all smart functions. but all cable channels were gone and it was easy getting them back, but they would not open. I called TCL help line and they worked me thru the problem, but did have to reset the tv by unplugging it-waiting for a bit then plugging it in again. All was well then and I DON'T KNOW WHY, BUT THE PICTURE SEEMS TO BE EVEN BETTER THAN BEFORE. Help line was very good and stayed with this 91 year old until all was fixed'

      UPDATE: Close to seven months since I got the fire tv and I THINK IT WOULD BE very hard to duplicate the value. I have found that most smart tvs have issues to deal with and with the few that I had they were easy to fix myself or with a call to a very good customer service line. I would buy this in a heart beat!

      UPDATE: Have had this TCL tv for one year now. I am confined to four walls and a tv in a skilled nursing home and I can tell you that I appreciate and regard this as one of the best purchases I have ever made. I have had some small issues that were not the fault of the tv, but still handled by the TCL help line. They were so good to me and fixed all the little problems. It is a wonderful buy!

      Arrived before expected packaged well. No damage. Was hard to find the holes for wall mount...finally saw them amost on the bottom. So beware. Got it wall mounted and the mount shows on the bottom as the holes are so close to the bottom on the rear. Usually the wall mount holes are in the middle. So if you're going to mount on an existing one, beware. The set up was very easy. Turned on and it was already set up for our Amazon account. That was nice. Download and installation of apps was easy. Within an hour all was complete and was operating just like our old one. The picture quality is good....but we're not fussy. Some would say it could be better but at this price point I can say it was as good a picture as the one we replaced that was much pricier and died after only 4 years. The sound is better than our old one as well. I like that the remote is the same as the one we had for our fire stick, which we no longer need. Overall, I've very happy with this TV and the entire transaction.

      This is a great TV. However, with low cost, comes the inevitable problem. And in this case the issue is with the "Display & Sounds" menu which displays an empty gray screen with a white bar, or, when the menu is selected, the screen goes dark. Restarting the TV fixes the issue, but clearly, the firmware has issues and TCL has known of these problems for a very long time and still the issue persists. I have also found in my research that this same problem is seen on other FireTV vendor sets. So it may be an Amazon thing. I don't feel like going through the hassle of a blame game with either TCL or Amazon and the picture is "good enough" but clearly, I am one of MANY who have a non-working function on a television that should allow us to control our display and sound functions out of the box. The photo above shows the issue I see with the display & sound menu.

      Other than this, the set is good. I use a amplifier for the sound and thus cannot comment on the native speakers so many have dissed, but for my purposes, it is a good match for my needs. If I had it to do over again, I'd spend the extra $50 to get a higher quality unit, but even then, with these software-based TVs, it seems to be a crap shoot if you are going to get good firmware, no matter how much you spend.

      All in all, adequate quality. Not stupendous, but not bad for the price. If this set does not stand the test of time, I will go with another brand and definitely not with a FireTV. It is my hope that whoever is responsible for the firmware issues, steps up and issues a fix that truly repairs the problem with the display and sound menus. Two stars removed for whoever is not fixing the firmware issue. If I get help getting a patch pushed out to me to fix this, or another set that actually has a working menu, I'll edit the review and update accordingly.

      I had low expectations for this TV, for $269 for an 55” smart TV, and to be honest, I was prepared to return it if the picture quality was bad. But I was surprised at how great the picture quality and sound are! I wanted it for an outdoor showing of the Eras Tour for a large group of friends and had planned to show it on a projector and screen but it was too bright when we did a dry run the week before the event, so I purchased this on Amazon in a bit of a panic, with a hefty dose of skepticism. It was easy to connect it to external speakers for our outdoor performance. I had the option to enable it with my current Fire TV settings, so when it arrived, set-up was so easy, it was essentially plug and play. All my apps were loaded and ready to use. I’ll be keeping this TV, it’s great!

      I replaced a 39" 1080p LED tv with this 43" 4k Fire TV. I like this TV very much. I stream shows from multiple apps on my Roku, but now I don't need the Roku because this TV has all the same apps I was using. I mainly game on this TV on an Xbox series X. There are many settings available and there is an auto gaming mode that is enabled while gaming(a little icon pops up saying it's going into gaming mode). Many settings are the same type you'd find on any brand of TV, but this has some settings that were new to me. You can set the TV speakers to automatically apply a Dolby Atmos effect which surprisingly sounds decent on the small TV speakers. Dolby Vision HDR looks great on games that support it which there are many. For the price I paid for this TV I am surprised how good this TV is and how much I like it. The TV speakers really are good enough to use on their own(No bass, good vocal audio, decent all around), I did connect the TV via Bluetooth to my stereo amplifier which is connected to Kef speakers and a subwoofer, Bluetooth sounds excellent on this TV. If you get this TV and plan to game on it with an Xbox Series X, don't forget to adjust some of the settings on the XBOX to make sure 4k is enabled, Dolby Vision is enabled and the correct Stereo, Dolby Digital or Dolby Atmos is enabled for your sound system. On my stereo speaker only setup, Dolby Digital sounds best while gaming on XBOX.

      I am not sure where to start. I seen the thousands of reviews. I thought it’s a decent price for at $300 to arrive in a few days with an easy Amazon sign in set up. I liked the idea of using Amazon Alexa to assist with the tv.

      The biggest issue was my remote did not work. The app remote with my iphone also did not work. Not sure if there was a Bluetooth issue but I could not access any functions for the TV because it did not get past the set up stage without the remote working. The TV did cut on. It just did not get past the pair the remote setting. Which was worse. I would have preferred an obviously broken tv because I spent hours trying to resolve the problem.

      I contacted Amazon. I went through the step by step process to reset tv, remote. Change batteries brought new batteries. I was then referred to TCL.

      I repeated process.

      I did not work. They offered to send me a new remote. Without the Bluetooth remote I guess the tv is just a paperweight? I was then told to just return the tv through Amazon.

      I then returned the tv and bought a tried and true Roku tv the same day at Best Buy.

      So it is nearly 30 DAYS later on July 31 when they said my refund will be issued. They updated the refund today for 8/2.

      It has been a very frustrating experience. I’m happy for everyone that received a good tv with a functioning remote. I would warn anyone that has never used TCL the deal was not worth the trouble at all. Also still have not been refunded.
