I posted some info on how to fix it if you are handy.
Thank you so much, that wasn’t a bad deal for that 70 inch I’m going to look at Costco I’m not handy what so ever and I don’t even want to fool with. And this time I’ll make sure i get an extra warranty.
Yeah, you can’t go wrong with Costco. Better price. Longer warranty. Cash back.
I will likely spend the $100 and fix it at some point and give it to a family member.
It sounds like you have done everything. If you purchased insurance, get a replacement other than Roku/TCL ! Mine was doing that too. I did exactly what you did. However i also did the FACTORY RESET. WITHOUT providing an email, and without setting up and Roku services. Plus my relying 100% on antenna and WiFi I could only stream. Once I did the FACTORY RESET, the picture returned.
I have the same problem I can hear things. The back light works all the time when booting up and right when it is about to go to home menu it the backlight turns off slowly like when you turn off your phone. I go to settings to see brightness settings and its on brightest. Idk what to do.
@JTV119166, try taking it off the brightest setting. It's probably the brightest setting that's killing these backlights.
