I would hold the reset pin in and plug the unit into power and hold the pin in for 20 seconds. leave your console plug in and see what comes up. If you get jibberish, then try changing the console speed. If you usually change it, try whatever speed you normally change it to. If you don't get any jibberish at all, then you may have a defective wireless access point. I have had issues with 1242's and I just keep on resetting them until it comes up. Make sure that when you are resetting the access point the color of the light turns a reddish color in order for the factory default to take effect.
