My Fetch TV has stared having a very dark picture. Was working fine last night but now can barely see anything (including the menu). The tv is fine as all other inputs work. HDMI cable is fine as the issue is same on different cables. Have tried both hard and soft resets of the fetch box.
It's not great to hear about the dark picture on your Fetch TV.
Just to clarify, could you confirm if the TV brightness settings are in place? Could you also confirm if the dark picture is only when connected to Fetch or on other apps outside Fetch as well?
