Home button 5 times
Fast forward button 3 times
Rewind button twice
If that doesn't work settings > system > advanced system settings > factory reset
Try unplugging the tv and plugging back in that worked for me
Try unplugging your tv and plugging back in. That worked for me. I have an Xbox s and ps5 it did the same thing on a Hisense Roku tv
