I haven't swapped out my cable box yet, but I was wondering if anyone is having the same issue with their tv. I have the UN60D8000 and I noticed every now and then, I lose my picture and sound for about 2-3 seconds. This happens like once or twice everyday. It comes right back and everything is fine, but what can be causing this? TV ? Cable box? Just wondering if anyone else is encountering the same thing. Thanks rick

I don't have the UN60D8000, but I'll take a shot.


I assume you're using an HDMI interface. Perhaps it's losing the authentication (HDCP - which means copyright protection) and the cable box needs to reset the authorization. Do you see anything on the cable box's front panel, like "DVI" when this occurs?


OTOH, it shouldn't happen in the first place. Intermittent problems are tough to figure out, like is it only on one channel? That sort of thing.

Actually, it's "content" protection.

AFAIK, once the "authorization" occurs between the source and destination devices, you should not lose (or have to re-authorize) the signals. So, IMO it's either a loss of signal (or bad signal) from the cableco, a bad cable box, faulty HDMI interface on the TV, faulty TV, or faulty HDMI cable. Of course, this is all assuming that the OP is using HDMI.

Does the problem ever happen when watching DVD's?


I'd suggest starting easy. Unlug the cable box and TV from wall power for a few minutes. Re-seat the HDMI cable at both ends and power everything back up.

Thanks for the replies.....Nothing changes on the front of the cable box.


I don't notice it happening when watching a DVD, but I don't watch a lot of those. Maybe I'll try swapping out the the cable box.


Thanks

Are you using HDMI between the cable box and TV? And again... try a "hard" power cycle of the TV and cable box as suggested earlier.
