How to determine if HDCP keys are revoked Samsung UN46D6000SF

[AcGeorgiegirl]

My tv has had "No Signal" when hdmi cord is attached to any hdmi port, from my cable tv stb. The TV says, "Check signal cable" once I unplugged the hdmi cord from the port. I've made sure the device I'm using can work with other TV's in my house, no problem. This TV will work with hdmi connected from a FireTV stick, though.

Maybe go to the samsung site and try a firmware update if there is one.

Yeah, thanks, I'd done that, as well as reset to factory.

How many other hdmi devices have you gotten connected to the cable set top box

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

maybe update the settop box (which is what model?).

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

I don't have any other hdmi devices currently plugged to the STB. It only has one hdmi out port. In the past, I've successfully connected 2 other tvs to the hdmi.

The box is a Cisco Explorer 464OHDC2.

unplug both the stb and tv from power. disconnect the hdmi cable at each device.
reconnect the hdmi cable. plug in power at the TV, turn it on.... does it see that that the hdmi incoming port is "occupied" by a cable (ie. not greyed) but no signal is received?
IF so, power up the stb box. does the tv status change?
Samsung hdmi implementation is not certified so there can be interop issues. Further, lots of stb boxes also have implementation issues... perhaps a replacement box is necessary.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

I had the stb's power still unplugged when I reconnected the cable. The tv said, "Check Cable", and the port wasn't grayed out. Then I plugged the stb in, and the message changed to "No Signal". I've actually had the stb replaced recently for this problem, but it made no difference. I don't have any other device to test the hdmi ports on the tv with, except a laptop. Would that help?

test the cable on a different tv.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

test the cable on a different tv.

The cable works fine.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

if the cable works fine, the box works fine, and the tv works fine.
then probably your box is set to output some resolution or frequency that the tv cant handle.

i have seen this when connecting European PS3 consoles to monitors - the monitors dont like 50Hz sync.

good "observationing". As you can see from your "tests", the tv does detect that indeed the hdmi cable is plugged in, hence the "plug detection" circuitry appears to be fine. Then upon powering up the stb, the "edid" work along with a few other things take place in the hdmi protocol before video happens. The error, "check cable" appears to indicate a physical layer issue as opposed to upper layers / apps (ie. hdcp). As part of the "edid" signalling, the source attempts to "read" the display's capability. Failure to do that would like represent a "lower layer" issue (physical) as there usually isn't much going on as it is a pretty basic "memory read".

Since the "firestick" works, it appear to indicate an issue with the stb interoperating with samsung's hdmi implementation... maybe. There are lots of posts thru out the internet with stb issues with samsung (and others). "Fixes" that I have read, usually point to software updating of both display and source, box replacement, cabling, and "wishing"... :-)

go back to the other display (the one that works) with the same box and cable.
check all the settings in the box including things like "deep color", "color space", "auto", etc. Try turning off anything or setting "auto" to a specific setting. Further try setting speed to 720p.

Last question: has this ever worked with this display?
Next to last question: what software is the stb running?

Thank you for the techie background info for how the hdcp thingy works...very helpful! Your question of whether the stb has worked on this tv before...no. In fact, the guy who I bought the tv from also was using the same cable company's stb, and he sold it because it began not displaying on hdmi ports, as well.

I'll go through the settings, as you've suggested, of the stb while connected to my other TV, let you know.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

The stb settings allowed for just basic video choices, and I took away the 480p & 480i. that left 1080i and 720p. This didn't change anything. I then adjusted the tv's settings as I tried with the stb..nothing changed. I then went into the stb settings, and took off the 1080i, leaving only 720p(while still connected to the TV that has the problem). Nothing changed.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

what software version is on stb?

ensure that you have turned off CEC (anynet) in the tv.

how long is the hdmi cable that you are using?

[AcGeorgiegirl]

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

I'm working on getting the stb's software version. Anynet was on. I turned it off.

[AcGeorgiegirl]

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

The software is "VCS version for CIDTV 2.0.9.004 for 8-bit set tops"
Also, the date was 2010-2011

[budwich]

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

I don't think that is the firmware version for the stb... that's the software version for the caller id "app".

turning anynet off is good BUT it think you might have to go thru some "sequencing" like I suggested earlier (unplugging, powering, etc).

yep, it is the caller id thingy, sorry! I hear ya on changing the AnyNet choice/unplug, etc. I'll try that next.

Re: How to determine if HDCP keys are revoked Samsung UN46D6000SF

I overlooked your previous comment about the original owner indicating that the tv worked at one time with the "same box" but then stopped. Since it works with a firestick (and probably with the your pc... you can try that too, just confirm), it does appear to point to the stb. from my reads, this stb box appears to have limited support.
A check of the firmware would be wise (haven't seen how to do that thru the documentation... very poor, but expected from stb makers). I suspect that perhaps a software update may have "broken" things perhaps.

Depending on what you have access (even thru friends), you might try wiring in some sort of intermediate hdmi device... receiver, splitter, switch,etc that might act as a "buffer" between stb and tv.

when you indicated that you checked for a tv update, did you actually try a "usb based" update or just a "check for update"? what version is on the TV?
