I have the Onkyo TX-SR606 connected to direct TV. Programmed the satellite
remove to interface with the receiver. Worked fine for a while but now when I turn on the receiver it automatically goes to game instead of cable tv. Never connect a game to the receiver. Made a lot of changes do not know how to make cable my default when the receiver is turned
Try to take the game cable off the receiver and then see how. If the problem is still the same, try to change to a new receiver.
