I have a Sony DIRECTV Digital Satellite Reciever SAT-A65, somehow it is not sending a signal to the TV. Seems like I need to re-set it but no re-set button. Normally it has been working just fine. All other TV"s in the house that use DIRECTV recievers are still working fine. Maybe I hit something on the remote, but can't seem to figure it out. Need help. Thanks
