Troubleshoot "DVI Repeater"

I am running a Sony Bravia XBR4 thru an Onkyo TX SR705 receiver, & have started getting this sign across the tv screen, " found a DVI repeater". It only comes on when we view the tv with the Onkyo, not when viewing the tv stand alone. We have not moved or altered any cabling & have had this setup since first installed six months ago without incident, we have changed NOTHING. I am wondering if someone in our household has hit a button on one of the various remotes. The only way to get rid of this signage is to change the channel back and forth or to turn off the Onkyo receiver and watch the tv without it . It only appears while watching the satellite, NOT dvd's.
Any suggestions are greatly appreciated.

Thanks Biker;
Will give it a try.
Thanks.
