I would start with a reset to the Slingbox. If the lights do not change, you may need to try a new power supply. I have linked an article that will explain how to reset the Slingbox, and another article that talks about the same symptoms you have mentioned:
- Slingbox.com - How to reset your Slingbox to factory settings
- Slingbox.com - Slingbox won't connect; won't reset; all lights on but network
Hope this helps!
Thank you for your reply to my request for help. I previously reset my Slingbox with no change in the problem. I also found a compatible power supply and connected it, again with no change. I read on another blog about replacing capacitors, but I haven’t figured out how to open the case! Do you have any info on that? (capacitor replacement or accessing the inside components).
Thank you again,
I think you will find the capacitor problem was limited to a batch of Solos, I don't recall a Pro-HD ever being affected. As for Power Supply, I would be wary of a 'compatible' one. As you will have seen from searches on the forum, all Slingboxes are very sensitive to the power supply and you can really only test the box with a proper Sling-supplied one. Unfortunately if that fails it just means your Slingbox is 'shot' and you will have wasted your money.
I have an older SB300-XXX that I don't use often but has still worked well until a couple of days ago when I noticed that the streaming 'horseshoe' lights were on steady. I tried to connect but was unable (no connection to the internet). The network light is not lit. I have tried the following: disconnect/reconnect power cord; disconnect/reconnect ethernet wire; disconnect/reconnect router power cord; depressed slingbox reset button for 30 seconds - all to no avail. Power light and full horseshoe lights are the only lights displayed. Any ideas? Thanks,
