Thanks for using the answers forums. Sorry to hear you are having problems with the power on your SlingCatcher.
At this time, we no longer manufacture the SlingCatcher, so we wouldn't have a way to repair it, however we do have a few options. You may want to look in to purchasing a new power supply, that may be the power issue fix. If that still doesn't work, you may want to look in to the newer connected devices that we do support such as the Netgear NeoTV, WD TV, or Sony Internet Player with Google TV. Below you will find links for both the power supply and information about the connected devices.
Hope this helps,
