I have succesfully replaced my lamp and need to reset my lamp timer. When I go to my ISF Calibration menu on my remote it prompts me to the next task setting and does not let me go to the selected ISF calibration menu. I have gone through 2 lamps in very little time. My first lamp went out with only 338 hours. My dealer replaced it with another lamp and then 7 months later lamp 2 has failed. I have no idea how much time is on the lamp 2 but I know I have not made a 1000 hours yet. Dealer wanted $750.00 to replace the second one and told me the lamp warranty has expired by 1 month. Needless to say we have not use a 1000 hours and I was able to find the lamp online for $266.00 and saved a lot of money. The lamp turned out to be identical Osram I believe the name. I followed the owners manuel but I can not figure out how to reset the lamp timer for it does not let me go into the ISF. Please help thanks Michael
