Bests & Worsts Reviews from Amazon

I must be one of the unfortunate ones. Thankfully there's Amazon's customer service 'cause TCL's is dismal. Buyer beware if you need to contact TCL support. I bought the unit just under a month ago. It worked fine for two weeks. After two weeks, it would turn on and appear okay, but after a few minutes you'd hear a hum/buzz that would get louder over a few minutes, then the video would go blank. Audio still worked, but no video and no pressing of any mouse buttons would bring it back. Unplugging and immediately replugging wouldn't help either. But unplugging for an hour and turning it on worked, only the problem would happen again. It was sort of like something tried to warm up and when it did, it just died. I tried all factory reset options... tried reseting via the button on the side. The sound before the video went out was from the back of the unit, not the speakers and was unaffected by speaker volume. I initially tried to replace it with Amazon but they were out of stock so I started a return process (since you only have 30 days on devices like this). With the return started just in case, I reached out to TCL. They are slow. The send duplicate emails. They take days to reply. They do not communicate well. Despite sending the serial number and proof of purchase, they wanted a picture of the serial number and a video of the problem (hard to upload a 3 minute video from a phone when their website limits uploads to 10Mb). After 10 days of back and forth and with only 3 days left to return it to Amazon, they finally called me. They wanted to send out a tech in another 7-10 days to repair it. If the tech couldn't repair it, then they wanted to send a tech with a replacement after that (another 1-2 weeks). I offered to give them my CC to secure it and asked to ship a replacement and I would return the old one, but they said they cannot do that. I work and can't wait for a tech to come to my home to do a repair for hours and possibly have to return again. Plus it would be another week to three weeks before I'd have a working TV... which would be too late to return it to Amazon and would now be an item with used, replacement parts in it... this for something I'd had less than a month. I've seen some good reviews for these and some bad ones. I understand tech fails. But its the TCL technical support that really failed here. In the end, I saw Amazon had these in stock again... so I cancelled the return, and redid it as an exchange. New TV will be here in 48 hours and I have 30 days to return the bad one to Amazon. No waiting 7-10 days for a tech... and 1-2 weeks for a new unit if repairs can't be done. I just put the bad one into the replacement ones box and drop it off at UPS. Thank you Amazon for having such great customer service. TCL... I will never deal with you again.
