Have you tried hitting "Don't Accept" and restarting it and then choosing "Accept"?
It sounds like a glitch - but one that should have been taken care of with a software update. The other variable is that a router setting may be denying it, but I wouldn't know where to start with that. If you want to eliminate the router variable, connect the TV straight to the modem via Ethernet and see if you can launch the Internet@TV that way.
I haven't seen this at all, but if you can't get it working, let's get a technician out to you to see what can be done to fix this.
just hooked up a LN46C670 from BestBuy.com, wired to home router and "passed" connected to internet test onscreen, However when I push the iTV button the screen grays and a long "disclaimer statement" appears, press the AGREE button , says "loading" then the "diswclaimer statement" appears, I AGREE again. No matter how many times I AGREE it keeps looping back. If I exit and try to navigate to settings, or samsung apps, it won't go there. I did an online software update successfully, still does looping back to disclaimer. I did a factory rest to original Firmware and reinstalled update, same result. Anyone else get and solve this
