OK. You need a pioneer remote control, original is the best choice; they are available on e bay. This also works on Pioneer plasma TV, Plug in the media receiver while it is connected to the plasma TV, and engage the remote control as Follows.. Press……. DISPLAY……… < left arrow ………Up Arrow……… < left arrow ……….. > Right arrow……….. then press the ON / OFF button on the remote, The condition that you are experiencing is called LOCK OUT and was caused by applying electric power to the unit with the metal case not in place. A small white button engages when you removes the case and lock out the main circuit board.

The media receiver has one “achilles” heel and that is if anyone removes the cover from the unit and plugs it in, the system goes to lockout and the indications you mentioned would be evident, blue light, red light, and orange light, all ON at the same time. The system protects itself from intrusions into the technology that is protected by trademark. The system can be reset if you have the remote. Please reply if you need that information since the post is a few months old.
