May I suggest you disconnect the receiver from the power supply, then give it one [1] minute, and then reconnect to the power supply, when picture appears on screen then press yellow, blue, green, and menu, but you have to do it quickly like 1234 do not leave an interval between pressing each button. Other than that, I can only assume your receiver does not have this facility, or that the receiver is faulty, in that case you will have to return the receiver to the dealer from whom it was purchased, hope this helps ok.
