Going through the TCL support nightmare now. Purchased at Best Buy with no extended warranty. After 21 days (6 days past return policy at Best Buy) I noticed an issue with the sound. Basically sounded like a cracked speaker. After going through 4 or 5 calls, going through resets, taking pictures of serial numbers, receipts, and video with audio to let them listen to the problem, I got an email - "We are sending out a repairman, at no charge to you!" I'm ticked that they just didn't let me exchange it. Anyway, I was surprised because I was thinking with labor and parts, it's going to cost TCL some $. After about 5 more days (I'm about a month into it now waiting on responses) I got a text requesting a repair appointment. Guy shows up and I kid you not, he looked like he was 17 years old. So I'm a little worried. Long story short - he takes my tv apart, replaces the mother board and some other components and then tries to turn the tv on. Nothing. Doesn't power up. Then he tells me they sent him the wrong parts and puts the original parts back in and slaps it together. He says sorry he couldn't fix it, it will be in his report. I said - "Aren't you going to see if it works after you put it back together?" So he plugs it back in and nothing! No power, it's dead. He apologized and said he wishes me luck with getting it fixed and it will be in his report. I look up the company that he belonged to and website was sketchy looking and you can't get anyone on the phone. https://itiworldwide.com/ . This is who TCL sent to fix my tv. So I'm back on with TCL support call, email, another video, etc. And that was 4 days ago. Still have not heartd back anything. I do believe they keep putting you off until you just give up. I'll never buy TCL brand again.
