I have a TCL 50S535 with a Denon S760 AVR connected over eARC. I also have a Roku Ultra connected to the Denon via HDMI. It has worked perfectly for years. I just got the 12.5.5 4174 update and the TCL has problems connecting to the Denon and the Ultra. It asks if it's online. I tried both unplugging and factory resetting the Ultra. I get the dancing Roku and then it can't see it although the Ultra Dolby Vision logo comes on, dims, and then the TCL " Is it..." screen (seems like resolution problem). I then tried accessing my Denon in Setup mode and TCL can't see it. I get some flashes and then the TCL "Is it..." screen. This setuo has worked perfectly since I got the Ultra (had a CCwGTV before). Any solutions? Would a Factory Reset on the TCL fix it? Who's the updater, Roku or TCL?
Hope someone can help. I did try getting to Roku Supprt but the Lading... just sits there after selecting Device.
Might have to go back to the CCwGTV, but I hate it.
