Just picked up the 55US5800 yesterday from Target. Upon setting it up it was unable to find any wireless signals so I had to use wired and after it installed updates and trying to restart it froze... I turned the TV off and tried this again to get more freezing upon restarting. Upon trying to factory reset it froze again... I then attempted to skip the connect to internet step and manually update the software via usb stick. This worked until the TV tried to restart then then again froze..... thank god I'm able to connect it to my ps4 right now but this means I can't get any 4K features out of it... Kinda feel like I just brought a 55" piece of garbage into my house. Not the best first experience with TCL.
