2000 Honda Accord AC control panel issues

I have a 2000 accord and the control panel for the AC/heater keeps flashing on and off. When it is off (no lights lit up) it doesn't respond when you push the buttons and semi warm air comes out when I turn the AC on. Randomly, the lights will come back on and it will again be responsive. It usually happens (going on and off randomly) for the first few minutes of turning the car on, but will then stay on. Any ideas?
