I recently switched to Direct TV. I purchased a slingbox 500 in 2013. When I switched it to the new HD box, the TV and the HD box won't turn on. If I manuely turn on the HD box and start my slingbox in my ipad my TV turns on. Also, when I disconnect slingbox from my ipad the direct TV HD box and my TV remain on. Previously with the cable box, my TV would not turn on when viewing slingbox on a secondary device. How can this be fixed.
