Has anyone come across where your Roku tv turns on and off by itself? I have a 65 inch Onn roku. Just had it for about 4 days. I’ve looked on google some people have said using a wire hanger of some sort and hit the reset button and hold it for about 15 seconds. However, their tv is a different brand than mines. Can anyone help me out as to how to fix it?
First thing I would try would be a system restart (not the same thing as turning off and on). From the Roku home screen use menu path Settings > System > Power > System restart. (On a separate Roku device the menu path is Settings > System > System restart.) If the problem you're having doesn't let you control the Roku via the remote, you can restart by pulling the power plug for 30 seconds or so then plugging back in.
If that doesn't fix it, the factory reset you were describing requires you to hold the reset button, which may be behind a pin hole, for a minimum of 30 seconds. Alternately you can use menu path Settings > System > Advanced system settings > Factory reset. Either way this will clear out the unit's memory and you'll then have to set it up again as though it were a new unit right out of the box.
