I have been running a solo on an old solo on an ancient tv with the red, yellow and white wires connected to my tv. Do I need to be hooked to the tv to use the sling or can I just hook to cable box?
To answer your question, you do not need a TV for the Slingbox SOLO. It'll work perfectly fine with just the cable box connected. All you would need to do is remove the cables from the TV and the Slingbox Out ports.
Hope this was helpful!!
