Hello, can you tell me what the best software or firmware update is for my TCL TV Model U65E6800FDS 4k 3d tv, bought in 2016, and do you have a copy of it, I can boot up via usb, as this tv will only come on with white screen and logo, and thats all, so maybe an update will fix it, can you help, I'd really appreciate it, thank you.
Steve
