I own a Pioneer Elite 610 HDTV that was ISF'ed when I lived in Chicago. The ISF Technician did it improperly because the screen is almost black. I have had properly done sets in the past and this was done incorrectly done. Unfortunately I was not home during the process and my wife did not know how to evaluate the job that was done. The technician has not returned any calls. I have downloaded the service manual and I have looked in service mode to see if I can restore the factory default settings. I was unable to locate how to do it as the manual I have is incomplete or it is not in the manual. All I want to do is go back to the way the TV was shipped to me so I can make my own modifications using a calibration DVD. Does anyone know how to reset the 610 to it's original shipping settings? Thanks in advance for your help.
