Hi. Yesterday my wife was driving her 2004 Honda Accord LX V6 AT and the radio/HVAC display went blank. The radio still works. This car has 56K on the odometer. I searched on the net and found a mention of the Honda's TSB 01012004 "RADIO DISPLAY OR UPPER DISPLAY IS BLANK" which seems to be addressing the problem I have. Of course it's hard to tell without seeing the TSB's text.
