TCL Roku TV stuck on logo screen

Update... problem solved! I unplugged everything from my TV to make sure that something else wasn't causing it, including the flash drive. It still did the same thing. So finally I bit the bullet and did the factory reset on it... I held the button in for 38 seconds and it rebooted back up to the language screen just like it was the first time it was ever turned on after I bought it. I went through and set everything up and so far it's working like a champ. The only thing that wouldn't work properly was the flash drive for the live TV pause. It wasn't detected  at all. So I put a new flash drive in it and formatted it and it started working properly also. So I don't know if it got an update that was corrupted or the flash drive went bad and caused the TV to freak out. I would think if the flash drive was bad it would have straightened up when I unplugged it but it didn't. Regardless, it's working like a champ now. Hope this can help someone else.
