[OS 12.0] Flashes on TCL Roku TV

I just bought a 55 inch TCL Roku TV (55S555) and immediately after updating it, half of the apps continuously flash so bad every few seconds that it gives me a major migraine and feels like I'm about to have a seizure. The worst apps are ESPN and Paramount +. Some apps seem unaffected like Hulu and HBO Max.

I didn't pay for a roku tv only to have to get a new streaming device that actually works. If an update can break half of the features of this TV then what's the point? I have tried factory resetting, leaving picture settings alone, changing picture settings, going through brightness settings, unplugging and holding power button, etc.

From what I can gather it seems to be caused by the 12.0.0 update as it only affects certain apps and not HDMI connected devices. PS5, PS4, Switch through HDMI haven't had a single issue. TV is going back to Best Buy tomorrow and I'm not sure if I even want to try a new one. This is not the experience I was expecting after all the positive reviews and recommendations I researched before purchasing the 55S555.

I'm experiencing the same thing even when I start my tv it's flashing on the right side.  Hulu is the only app I use and noticed the flashing on brighter scenes.


I have TCL 55R617 tv.  Only 4 years old so should not have hardware issues.  No HDMI cables are plugged in, just power.

We're sorry to hear that you've been facing an issue when playing content on the Hulu channel and we would like to know how to identify and resolve any playback issues.

For us to better understand the issue you are experiencing, can you please provide us with the following information:

  • When did this issue first start occurring?
  • Have you tried removing the channel that you are experiencing the issue with from the Roku home screen? Then, disconnect your device from power for a minute. Plug it back in, then try to add the channel back once more and see if this clears up the issue.
  • What troubleshooting steps have you taken so far to try to resolve the issue?
  • Tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times and provide us with this ID)
