I'm having a similar problem with my remote for Roku onn. Evey button turns the TV off and on except for the power button which isn't working at all. I know it's a remote problem because my phone works fine as a remote when it lets me "wake" the TV. Any suggestions?
Yes!! So I was up late trying to figure why the remote was going crazy. I finally gave up but had to take the batteries out, otherwise, the red light in the front sensor kept flickering. I left the batteries out all night, and decided to give it another try, I put the batteries back in and worked perfectly normal. Maybe it worked as a reset? 🤷🏻♀️ But beats waiting for the roku ppl to reply weeks later (just to say, it’s not our problem, contact the tv ppl) or ordering a new remote.
good luck
Mine did the same thing . I got mine back working properly I had to play with it a little bit but what I did was. Turn it on to home screen and hold the power button and left arrow button for about 10 sec then without lifting your finger keep holding power button and move other finger to right arrow button for 10 sec hope it fixes yours the same as mine
I just had this problem and no amount of searching the net provided a solution. After trying every idea with no luck, I realized that the power button was stuck down.
Use your fingernail or a knife to pull the power button up, and the issue will stop!!
