I've been using the One all this morning, and everything with the TV functionality has worked great. However, after I left the house for 30 minutes and came back, the TV won't display, giving me an error that reads "For some reason, TV took too long to start (0x8027025a)." I unplugged the hdmi cable into another port and switched inputs to ensure the signal was being sent from the dish receiver and it was. So into the settings I went, but to my dismay, I can't even access the One guide/TV settings section. It just keeps giving me the black screen with the TV image and circles me back to the above mentioned error....any suggestions?
