My Roku remote model: 100112176 code list version F1351-02 quit working for my Onn Roku TV S/N MB22211C32011508 model 100012589. I changed the batteries and did everything the troubleshooting suggested and still won't work. The power button lights up red when any buttons are touched but tv won't respond there is a red light on the tv but it is always there and it isn't doing anything special like blinking. It does howeverit is off at this moment while watching tv. As of this moment I'm using the remote on the app with no problems. Is there a way I can get another remote for my tv? Also where would I go to get one made for my tv or will any remote work that is Roku brand?
Since that is an Onn brand TV, you would need to contact ONN for technical and/or warranty support. Onn brand is known for a number of issues such as these as are most budget level brands.
If it's still under warranty, onn should replace the remote. If it's not, you can get the Roku simple TV remote or a voice remote. Many universal remotes also support Roku TVs.
