HDMI error/H1005 -hdcp link integrity check failed

I am having problems with my TV signal only when I turn it on for the first time. Blinks on and off, eventually gives me the blue screen with HDMI error/H1005. I have talked to tech support many times and have a new box with same issue. If I unplug the box and reboot it I finally get a picture. Everything is hooked up through my Yamaha receiver.  I have changed HDMI cables out of TV and out of box to receiver. ATT support thinks their equipment is fine. Seems to me if unplugging it makes it reboot and work fine it is their problem. Any suggestions??

Re: HDMI error/H1005 -hdcp link integrity check failed

Just because restarting the U-verse box causes it to correct the issue does not necessarily mean that the underlying issue isn't the cable.  The cable could be marginal and causing errors in the signal, enough errors that the U-verse box no longer sees the proper handshakes from the TV during a session.  Or, it could be an issue with the U-verse box.  Or it could be a combination of both.

Re: HDMI error/H1005 -hdcp link integrity check failed

Most likely the U-verse box. If U-verse’s solution to this problem is just
to bypass the HDMI port on the box and hook it up using component cables,
then it’s obviously a problem with their hardware. I have been told by
technicians that the problem is with the U-verse hardware. One technician
told me that the HDMI protocol doesn’t play nice with AT&T’s
anti-piracy/copy prevention system that is built into the STB. After using
12 different (new out of the package) HDMI cables and 3 different STBs
(that U-verse provided), I still constantly receive the same HDMI error.
This has been going on for years now.

This is why cable/satellite television is a dying media and is being
replaced with streaming services. I would get rid of my tv package all
together, but U-verse would force a data cap on me if I did. It’s actually
cheaper to keep my current TV plan and unlimited internet than it is to
just get my internet service through U-verse, pay separate subscription
fees to the streaming services and pay monthly data overages to AT&T. Great
foresight on AT&T’s part though. They saw this “cord cutting” movement
affecting their bottom line...So instead of adapting to it through the use
of innovation (the way Netflix did years ago), they decided to just lock
their existing U-verse TV customers in through the use of data plans and
contracts. Way to cage in your customers AT&T.

Re: HDMI error/H1005 -hdcp link integrity check failed

You can purchase unlimited capacity for $30/month, which is less than most of the U-verse TV plans.

AT&T didn't invent HDCP.  The studios caused it to be created and their contracts with AT&T (et al) require its use; it's also in BluRay players and any other consumer device that has an HDMI output.  The software implementation in the AT&T box may be faulty, or it may be the implementation in your TV is faulty.  If you've replaced 12 cables meeting the required standard, then I'd have to agree it's not just the cable.

Yes, using component bypasses the problem because component doesn't have HDCP built into it like HDMI does.  And subjective video quality may be higher or lower with component than HDMI depending on your usage and eyeballs.

Re: HDMI error/H1005 -hdcp link integrity check failed

My whole issue regarding using HDMI instead of component is not because of
picture quality. It is the way that my signal chain has to be formatted.
Unlike component (which only caries a video signal), HDMI carries audio. My
audio receiver has limited I/Os and I have to use HDMI in order to use my
television as a sort of “audio hub” so that all of my media devices will
transmit audio through my audio receiver.

As for the U-verse internet only plan... I was quoted a cost of $60/mo for
U-verse unlimited internet (no phone or tv) from a U-verse CSA through live
chat just two months ago. If it is only $30/mo, why the false information
from the U-verse CSA?

Paying $60/mo for unlimited internet with the additional cost of the
streaming services (i.e. Netflix, Hulu live tv, HBO, Showtime, Starz, etc)
would have been extremely cost prohibitive, and I still would not have had
the same amount of channels/content that I have with my current U-verse TV
package. If it does in fact only cost $30/mo for unlimited internet now,
then it will definitely be worth looking in to. I will contact them today
about the $30/mo price drop. Thank you for that info.

Re: HDMI error/H1005 -hdcp link integrity check failed

The $30 /month is to make whatever bandwidth plan you subscribe to have unlimited usage (similar to what have U-verse TV provides).  You still have the basic bandwidth fee (which you'd have anyway, with TV if you also have Internet).  There is often a multi-service "package" discount on Internet if you also have U-verse TV, so... if you had $50 Internet and $100 U-verse TV, you'd probably be paying $130 ($100+$50 - $20 multi-service discount), plus taxes and fees.  If you dropped TV and added the $30 unlimited in place of the $100 U-verse TV, then you'd probably be paying $80 ($50 + $30).  Still a $50 savings.

(Note; Other than the $30 monthly fee for unlimited usage, I'm really just making numbers up in this example).

For you it's likely your receiver.  Sounds like you are going directly from receiver to TV...my situation was different as I was pushing everything through a HDMI splitter.  Replacing the splitter worked for me.

Re: HDMI error/H1005 -hdcp link integrity check failed

We have the same problem and have switched out 3 HDMI cables and none of them worked.  Your solution is a "workaround".  The ATT box HDMI output worked fine with my older TV, but not with my new firetv. We know it is not the TV because HDMI from the TV works with several other devices.  So you are just saying we are out of luck if we want to use the HDMI output on the ATT box.  It is not a satisfactory work around.
