I've had the problem for about a week that's all over the internet about these TVs (and other Roku devices and TVs) where the TV boots into a red screen with the words TCL • ROKU - 4k HDR on it. After about a minute or so, it reboots (goes black) into the same screen. There's no way to turn it off (or on) other than unplugging the power cable, or to get it into the main system menu. I've tried all kinds of resets and unfortunately the remote is no longer paired with the TV because I put it into pairing mode while trying to troubleshoot the problem. Similarly, the Roku iOS app is no longer paired.
I know others have seen this problem and I've tried all the methods I found to try and resolve the issue. I'd really like to fix this, but have been looking at TVs from Cyber Monday and Black Friday. Unless I can figure this out, I'll never buy another TCL TV (leaning toward an LG Nanocell 8).
I only use the Roku software to switch HDMI inputs (couple of Macs and an Apple TV 4K) or to Broadcast TV channels via antenna, or to adjust settings on the TV. I use ethernet to connect to the internet and usually leave it unplugged unless I plug it in to check for software updates. I think I'm probably at 9.1 or so, but I might be about 9.2. So far as I know, I don't have the Disney+ app installed in Roku, but I do have it installed on the Apple TV 4K.
First, how does one update the firmware if the TV will not boot up, but just keeps booting and rebooting? Can you put the update on a USB drive and it just automatically updates?
Second, has anyone had this problem and been able to resolve it without calling a technician? I didn't buy an extended warranty because the TV is only 22 months old and my Samsung is about 16 years old and my Philips is about 8 years old. I expect TVs to last a while. When I called TCL support, they said to call a technician.
