Tuning Adapter blinking yellow

While watching tv tonight on my Windows Media Center which uses a Ceton tuner card with a cable card and a usb Motorola tuning adapter, my tuning adapter started blinking yellow. It's normally solid yellow and blinks red when changing channels.  I power cycled it and it's still blinking after 15 minutes. Every now and then I will see the red light light blink.  Of course now some channels like 1100, 1101, 1102, 1104, etc are giving me service unavailable. All the other channels are working correctly.   Not sure why this just happened but any help would be greatly appreciated.
