My late 2009 model Imac and Panasonic 32" HDTV suddenly stopped working together after seven months. The computer still recognizes the TV connection. When I got to Preferences/Display/Arrangement, the TV screen shows up, and when I go to Sound, Panasonic TV is listed there. So, it does not appear to be a problem with the cables (just in case I tried a new Mini DisplayPort to HDMI Adapter with no change). When I set the computer exactly as I have done for the past seven months then switch the TV to HDMI, nothing happens on the TV screen. This is maddening since it was working perfectly the night before but just stopped for no apparent reason yesterday morning. There have been no recent software or any other additions. Any ideas?
