TCL Roku 5103X. Was playing around trying to get mirroring so I could watch Facebook videos on the TV. Installed Chromecast. No luck. Installed Fire TV stick. Still no luck. Also added a casting channel. Now keep getting the following recurring message that pops up every few minutes -- even when the TV is turned off:
"VIDEO & TVCAST
UPGRADE TO PRO TO ENABLE AWESOME FEATURES LIKE REMOTE AND AD-BLOCKER."
I disconnected the Chromecast and Fire TV stick. Removed the one casting channel I'd added. Went to "mirroring" section under Settings and checked "Never Allow." Also unplugged the TV for a few minutes before plugging back in. Nothing worked. Still getting the message every few minutes and the only thing that works to get out of it is to hit the "Home" button. The TV right now is useless and I'm at my wit's end. Can anyone help?
Same keeps happening to me. But it will happen at any time: of I'm watching Netflix, if I'm watching YouTube. Basically any time I'm using the tv. But happens more at night and more on weekends than on weekdays. Seems to happen more when I'm casting YouTube from my phone. Can make the tv virtually unusable for long stretches.
I am having the same issue. It started this week. In my case it is playing some adult content. It is so annoying and I hope my roku is not hacked. It happened twice so far and I turned off power both the times when it happened. Just removed all channels I do not use. I do not have any casting apps on my mobile. My roommate has a roku as well and planning to check with him if he has any casting apps installed. Hope that resolves the issue.
I fixed it by accident. I went to settings --> privacy in Roku. There's a checkbox for ad blocker. There was no checkmark. I put the check there and restarted Roku. It didn't fix it. I then took off the check. Nothing. Then Roku restarted by itself and since being back on it's been working.
