Samsung blacks out 7-10 secs all the time.

[rivrbyte]

I have a Samsung 46” A750. I also have Time-Warner Cable with DVR service. I also have a Yamaha RX-V665 AVR.

I have One HDMI cable from the TV (mounted on wall) connected to my Yamaha AVR, and everything else is connected to the AVR, like the Cable, Sony BluRay, Another CD/DVD player that I use for playing MP3’s and regular Audio CD’s, a VCR is also connected to the AVR.

I contacted SAMSUNG because I have been getting blackouts on the TV with the sound still on that lasts for about 7 -10 seconds.

Samsung told me if I use the Samsung remote while it’s in this “BLACK MODE”, and try the volume, tools, and menu on the remote, and you can work these features, then chances are it’s NOT the TV, but maybe the Cable.

Does anyone else experience these temporary blackouts on their Samsung TV’s? And if you fixed this problem, what were the reasons?

One thing I have not done yet, was to bypass the Yamaha AVR and connect from TV directly to the Cable box,but I wanted to see first, what else the problem could be.

Thank you!

This problem comes up again and again and again. The problem is almost certainly an HDCP code repeater handshake problem.

Since your receiver outputs HDMI, it must have the proper repeated handshakes between it and any inputting device. A TV being an end device is only required to make one HDCP handshake.

You can test this by connecting your cable box directly to your TV. I would bet it will work fine. If it does then your cable box does not have the required HDCP repeater architecture. There are a lot of cable boxes that don't. If that is the case, then have your cable company provide a software up date if they can or provide a more up to date box if they can't.

Thanks TLS_Guy

Sounds like we are in the same ballpark. The STB is a Motorola DCT 6416 III. I have sent both Motorola and Time-Warner cable an E-mail concerning this HDCP repeater problem ...maybe I'll hear back, maybe not.

I went through the only manual I had for my last Cable box which was a DCT 6400 Series Set Top, and no mention at all with the HDCP repeater. Thank you.

HDCP REPEATERS ON SET TOP BOXES
A set top receiver connected to an A/V receiver via an HDCP encrypted connection may have trouble passing video signals through the A/V receiver even though a direct connection to the display seems to work fine. This relates to the HDCP protocol being sent and received, and the authentication process. This is not a fault of the receiver. Recently set top box manufacturers have become aware of this issue and some set top receiver manufacturers have already implemented firmware changes to their units while others are in the process of updating their units. If a set top receiver being used is having problems passing an HDCP encrypted connection video signal through an A/V receiver, contact the manufacturer of the set top receiver to see if an update is available.
The repeater bit is a part of the HDCP specification, which is available on the Digital Content Protection LLC web site.[1]
The specification defines repeater devices:
HDCP Repeater. An HDCP Device that can receive and decrypt HDCP Content through one or more of its HDCP-protected Interface Ports, and can also re-encrypt and emit said HDCP Content through one or more of its HDCP-protected Interface Ports, is referred to as an HDCP Repeater. An HDCP Repeater may also be referred to as either an HDCP Receiver or an HDCP Transmitter when referring to either the upstream side or the downstream side, respectively.
The specification also refers to a "Repeater bit" in section 2.2, protocol.

Your best bet is to generally take old the box to their office and request a newer one. Most cable companies will give you the newest box when you ask for it from their office.

TWC is very good cable though. Much better than the last rag I had.

i have almost the same issue as well, inclusing same TV and cable company. Actually, mine is worse... after a few seconds of black, signal degentrates to snow - in other words, hdcp handshake fails.

interestingly,my system worked ok, until my dvr's hard drive went. Then on the replacement cable box - same model, etc. - it would not handshake.

Cable company has repeately tried to reinstall software, etc... I think it's just a hardware intolerance. I've heard that poor hdmi cables can effect the handshake, so it stands to reason that a less that ideal internal connection in the box itself could also be my culperate.

good luck!

If they cant resolve and you need an external solution, look at this http://www.siliconimage.com/technologies/instaport.aspx. It stores the handshake key for seemless switching.

Here is more than you will ever need to know about the 6416. http://en.wikibooks.org/wiki/How_to_use_a_Motorola_DVR/Identifying_your_model

May or may not have any bearing, but have found it wise to defeat any proprietary interface between same manufacturer of components.
Anynet+, etc. They can be as much trouble as the convenience they promise.

What happens if you connect the HDMI from the cable box directly to the TV? Any blackouts? If not, perhaps a different sequence of turning on the components? This works for some folks.

Yes, this can make a difference. Turn on the source first, then the receiver and the TV last. That sequence worked well with my 6416, Denon, Samsung combination.
