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.
