So what you are saying, there is no power to the Slingbox?
With that being said, there can be something wrong with the power supply.
I would recommend that you contact Sling Media Support, at 1-877-go-sling.
Best of luck,

I can't get power to my slingbox pro either. I followed the steps in the manual of checking connections, restarting it, pressing the reset button and then attempting to reset with a 5 sec reset... nothing. I plug in the machine after having it unplugged for a few minutes and I am able to get the power button to come on for a few seconds, then it turns itself off. Even after going through the trouble shooting. So frusterating!!
I understand that your not getting any power to your Slingbox, I also see that you have tried the troubleshooting steps that we would have you try.
My recommendation, then, would be to contact Sling Media Support at 877-GoSling(877-467-5464) for further assistance.
Hope this Helps
