Screen blacks out...

[pjs234]

I have a Denon 2112 that I purchased in January of this year. It is connected to a Motorola HD/DVR cable box (comcast) and to a Samsung 52in HD TV. About 2 months ago, I started getting screen black outs. The black outs last about 2-3 seconds and the audio is not affected. It only happens when watching cable tv. Also, if I re-wind the black out does not happen again. The black outs are completely random and really don't seem to have any pattern as to when they happen (some days it barely happens, others i can have 1 an hr).

I was told by someone that this might be an HDMI handshake issue. Can someone confirm if this is the case? I am not all that tech savy, so I am not even sure what an HDMI Handshake issue is.... If it is a handshake issue, I understand that one of the work arounds is to run the HDMI directly to the TV from the cable box and then run optical cables from the DVR to the receiver for the audio. By doing this, I will loose my on-screen menus, which is OK, but are there any other options?

Most likely a handshake issue. But, if it worked fine before and started suddenly, I would start inspecting the HDMI cables. Be sure they are all plugged in firmly. It may be time to start swapping out cables and see if the problem disappears.

Indeed it sounds like an HDMI issue. Do you know if there was a recent firmware update for either your receiver or the cable box?

That have been a couple of updates to the receiver, only know because i had to do something to get them to happen. Not sure if the cable box has performed any updates, as they can happen without my permission.

I've got a 4311 and same thing. Changed to a new cable box (DVR)from a Atlantic 8300 to a Samsung ( Time Warner) and so far the problem has not appeared as of yet
