The support people are either lying or they need re-educating This is a well publicised problem with Slingboxes and there are lots of posts on here about this problem (I guess you didn't do a Forum Search for "no manufacturers" before you posted ?)
Basically your box is toast. Specifically U21, a TS1117 3.3V voltage regulator has failed. It's actually a known design fault and some people have got free replacement boxes from Sling Media, but I doubt that will apply in your case if your aren't the original owner.
Thanks for this info. I referenced this post when calling customer support back. They're sending a new unit even though I'm not the original owner. I didn't expect that at all, but apparently my box is still within warranty. Very generous IMO. While they wouldn't confirm that the error you reference is technically correct, they offered to replace the box based on the troubleshooting not working. Thanks so much for your reply. It definitely got me to stop wasting my time trying to make it work.

I don't like disagreeing with the moderators but I am not sure what Daniel is talking about here, I can only assume he didn't read your post properly. He is answering the question "My Cable box does not show up in the drop down list", whereas your actual question was "When I select Cable Box the drop down list says "No Manufacturers" and that is totally different. He obviously also hasn't done a proper forum search either.
By all means follow his suggestions but I think you are wasting your time.
