I have a TCL Roku TV 55S423. I had problems with it turning off for a second then turning back on then off again for a second. This happened about every 5 minutes. I had a thumb drive in the USB port for replay. Removed the thumb drive and the problem resolved. FYI. Software fix for the pause/replay?
I came here after my TCL Roku TV crashed for the umpteenth time. I just got the TV a month ago. It's got the latest software update version 9.2.6 build 4132.
When I say it "crashes" I don't mean it exits to the home screen. I mean it COMPLETELY SHUTS DOWN! It begins with it getting progressively worse response-wise when trying to change the volume or looking through an app's programming it begins to get slower and slower in response to the remote until it just "crashes" and completely shuts down then powers back up. It's done it with multiple apps and even when watching antenna TV.
A couple of times it kept shutting down and powering up 3 or 4 times before finally staying on. Then it will work fine for a few days before doing it again. I think it's a software problem and I hope they fix it with the next update and SOON!
I too have this exact provlem with my TCL Roku tv. cant be remote button being touched as i keep my remote on my nightstand its not app remote as Im not logged it gor that and the only one home most times. its the TV but Roku blames TCL and TCL blames Roku.
This may be related to a hardware issue, it's hard to tell. Have you tried contacting TCL support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
