Sounds like you may have a power issue on your hands. If the Slingbox is plugged into a surge protector, I highly recommend switching to a wall outlet. If you get the same issue in multiple wall outlets, it's probably an issue with either the Slingbox or its power supply. If you purchased that Slingbox from an authorized retailer within the past year, feel free to call us (1-877-467-5464) so we can replace any bad parts! If not, here's where you can get that power supply replaced:

P.S. We highly discourage customers from using power supplies from other products (including other Slingbox models!).
