We need to get more details about the connections with the Slingbox and the cable box. What type of cables are you using to connect the Set-top box and the Slingbox? Do you have a HDMI cable connected from the cable box to a TV? Take a look at this link,
I have the Same exact problem as you except im 300 miles away from my sling box. Does anyone know why this is happening? Can someone please help me

I have the same problem. Slingbox worked flawlessly until two days ago when suddenly it went out. I assume this is a software problem because all the hardware seems to be working OK. I have Time Warner Cable in SoCal with a Motorola cable box. I also cannpt re-install Slingbox to my Mac - it causes Safari to crash. Any suggestions would be most appreciated.
This has just happened to me as well. I have the Slingbox Pro HD attached to a Cox HD DVR cable box and Cox modem. It is really disappointing. It seems like I have had a lot of trouble with the Slingbox lately. Is there any way to resolve this. I am in Japan and my Slingbox is in the US. It seems like this has happened just since the firmware update recently. I miss watching American TV!
Thanks in advance for any help.
I just lost my video signal two days ago as well. Audio is fine. I can get a video signal with the yellow-white-red cables, but not with my component red-green-blue cables. Where I dial in from doesn't matter; I get no video signal on my home computer, nor from my traveling iPad. What should I check?
