46 inch series 630 hdtv

by gwingee / January 27, 2009 12:02 AM PST

can anyone tell me does this TV have the option for "variable" for audio? There is a sound bar I am going to get and there is one that has no remote that you can use IF the Tv has the variable option, otherwise there is another one for 60.00 more that comes with a remote and can be used ....I would rather save the 60 dollars if possible...I am disappointed Samsung does not offer the sound bar without the built in DVD

I would definitely be concerned. I wouldn't consider that normal operation. I've seen a few posts like that, but it seems to be a pretty common and easy fix.

I'll check on the variable audio and should have an answer soon.

Not Normal...

It's not normal, but it's not supposed to happen.

When the picture starts up with audio, is there a "Mode Not Supported" message on the screen, or is it just black?

Every once in awhile like a couple of weeks apart or longer my 40 630 samsung does the same thing. Now that I noticed this problem I'm finding out I'm not the only one...could it be the cable box has an output problem at times like something not booting up correctly? I have Comcast HD box.

I have Comcast HD box too...I hope that is all it is....but for what I paid for this TV and it only being a few months old, I hope it is nothing else...still waiting for the reply from the Samsung rep on this forum...

How I answer..

What's happening here is a limitation of HDCP handshakes - which is High Definition Content Protection, and the connection that must trasmit a signal that verifies that the signal is being sent to a screen rather than an unauthorized peripheral.

When the two units connect, a signal is already sent and a handshake occurs, the box recognizes the transmission as verified and sends the picture. When the box doesn't receive this verification - which could be a number of reasons - the signal is still there, connected and sending, but the picture doesn't get sent until the cable box can verify HDCP.

In most cases, if you turn off your cable box and turn it back on, it will attempt another handshake and then transmit the picture.

The reason I think it's the box(es, in this case) is because there is an audio signal present, but not picture signal. The audio is passed, and no "Not Supported Mode" display. This means that the box is transmitting a signal, but not a verified signal, thus, no picture is sent.

Had you seen the Mode Not Supported or Weak or No Signal Detected icon appear, then it would indicate that the television is not receiving a signal at all. But the television is receiving a strong connected signal (by the absence of a notation). What it isn't receiving is a picture THROUGH that signal from the box - again, likely due to the lack of HDCP handshake.

My bet would be that if you turn off the cable box and restart it, the picture will appear as normal.

Let me know. I'd be interested in seeing how this turns out.
