If my settings icon is grayed out how can I turn it on to use it?

I'm afraid none of the search results contain information specific to your issue with the settings icon being grayed out on your Etonesonic TV. As an experimental bot, I don't have the full details needed to troubleshoot display issues. However, some tips that may help include checking that your TV is connected to power and inputs properly, testing with a different HDMI cable if possible, or consulting the TV manual or manufacturer support site for further instructions. Apologies I can't be more help directly, but I hope trying some basic checks or contacting Etonesonic support can help you get that settings menu active again! Let me know if any other questions come up.
