So my AP brought my plane back after replacing the alternator and said, "hey, on the flight over the transponder didn't come on, probably just a blown fuse" so I went out this afternoon to check it out and the unit is powering up with the screen lit up and key backlighting on; but the screen is completely blank. I tried all the buttons and nothing. Holding "off" turns the screen off, but nothing I could do would get it to display anything.
Ideas?
