My roku tv keeps shutting off and turning back on and then cycling through the menu options and shutting iff again. I've done a factory reset, checked for updates, took batteries out of the remote and unplugged from power strip. I'm at a loss. Is my tv toast?
Did you ever figure it out? My tv is doing the same exact thing! I can't find any answers! Thank you!
It's not clear from the OP's post whether you can access the menus (op says they checked for updates, etc., which sounds like you can access the menus. But, the rest of the description sounds like the tv is on autopilot.). If you can access the menus, I would go to home>settings>system>power and disable fast start. I would also do the restart in that power menu (not the same as a factory reset in the advanced menu, although that might be wise to try too).
Finally, there should be a pinhole reset button on the back of the tv. I saw a video saying that unplugging the tv, depressing the reset button (with a paperclip), plugging the tv in while holding the button down, and continuing to hold the button until the front light flashes (some 10-20 seconds later) fixed a problem none of the menu restarts/resets could.
