My cables accidently came out of my cable box and now I have sound but no picture.
After plugging the cables back in, try rebooting the cable box, unplug the power and plug back in.
Also, how is the digital box connected to your TV? Does it connect directly to the TV or does it stream through a stereo or VCR/DVD player?
If it is by composite cable (red/white/yellow) or component cable (red/blue/green), make sure that all three colours are in their proper place on both the cable box and the TV. On these cables, two of the colours are for sound and one is for picture.
