System Experience​

Setting up my new Roku TV was a breeze, which I truly appreciated. The packaging was solid, and everything I needed was included right out of the box. I love when I can get a product up and running quickly without any headaches. It felt like a relief after dealing with complex setups in the past. However, I did face a small inconvenience when I realized I didn’t have the necessary adapter for my surround sound system, forcing me to make an extra purchase.

Viewing Experience​

The picture quality absolutely blew me away. The colors are vibrant, and the sharpness is impressive, especially for the price point. Watching movies and playing video games on this TV has been a game-changer for me. The gaming mode is a fantastic touch, making everything feel ultra-responsive. I was initially worried about the quality given its affordability, but it has far exceeded my expectations.

Audio Experience​

While the sound quality is decent, I wish it were a bit better. It can sometimes feel flat, especially during action scenes or while watching dialogue-heavy shows. I’ve noticed I’m often reaching for my soundbar remote to enhance the audio experience. It’s not a deal-breaker for me, but I do think it’s an area where the TV could improve.

Other Experience​

My experience with the Roku interface has been largely positive. I find it intuitive and easy to navigate, which is a relief since I’ve encountered some frustrating TV interfaces in the past. However, I did have a minor issue with the remote - it’s a bit small for my liking, and I’ve accidentally turned off the sound a few times. It hasn’t been a major inconvenience, but it’s something I’ve noticed.

Conclusion​

Pros:
One of the standout features for me is the value for money. The picture quality is exceptional for a TV in this price range, and the Roku functionality adds a lot of value with its vast streaming options. I also appreciate how lightweight and slim the TV is, making it easy to mount on the wall.

Cons:
On the downside, I’ve experienced a few minor software glitches, but resetting the TV usually fixes them. I’ve also heard some concerning stories about TCL’s customer support and product longevity, which does leave me a bit apprehensive about the future. I hope I won’t have to face any major issues down the line.

Overall Evaluation:
Overall, I’m quite happy with my Roku TV. It has delivered a fantastic viewing experience and has become a staple in my home. While there are a few drawbacks, the positives far outweigh them. I feel like I made a solid investment, and I would recommend it to anyone looking for a reliable TV that offers great picture quality and an easy-to-use interface.

So I got this TV about 15 months ago, right? I hung it up on the wall as soon as I took it out of the box. Fast forward to now, and it's being a total pain. I have to hit the power button like a million times to get it to turn on, and there's this annoying pink line running across the bottom of the screen. What gives?

So, I've been trying to get help from TCL Customer Support since October 13th, and honestly, it's been a total bust. My TV is still acting up, and I can't even watch my NFL games—like, that's why I bought the thing in the first place!

Seriously, save yourself the headache and go with a company that actually cares about its customers. It's pretty clear that TCL isn’t one of them.

Love the picture and the interface is pretty slick! But honestly, it’s a bit too simple for my taste. The remote feels just like the Roku stick, and I wish I could ditch those streaming buttons like Netflix and Amazon. I’d much rather have a number pad instead.

Also, this TV is super thin and light, but be careful when you're moving it! If you’re not careful, it could twist and crack the LCD panel. Seriously, it’s best to have two people on deck when you’re repositioning it!
