I just read your note on the sling box and wanna say thanks you saved me from buying a new sling box pro.
I had brought one about three years ago and it was fine till last night when it failed.
symtoms was the remote veiwing wasnt working the network light not lighting and reset wasnt working. It can see external video souces but the audio drops out and stutters on and off slowly.
I almost gave up but changed the power supply from a old sling box classic when I saw you had the same problems. Now its working and will be getting a spare power supply just incase.
