We would like to brighten the picture of our ROKU. However, all of the guidance from ROKU tells us to go to settings, then TV picture settings, then TV picture brightness. When we go to settings the option for TV picture settings does not exist.
We have never had this problem before. We have tried rebooting. When we first go to ROKU the brightness is normal and then it automatically dims within 30 seconds. Ready to throw out this piece of **bleep**. Should we obtain a new ROKU device?
