TV is on the latest version.  I've unplugged and re-plugged in the HDMI cable from the receiver and the TV.  I've reset the receiver box by unplugging it.  Still getting the same message, not able to change channels when I press the "ok" button. 

Thanks for your help!

Try a different hdmi port on the tv

Thanks, but still not resolved.

Do you have another HDMI cable to replace it?  Try unplugging the TV for a minute or so.

I've received a similar message twice this week on my LG C1 77" TV.  I'm using the correct cables and changed them twice.  This message was between my ROKU and LG TV so I don't know what's going on.

HDCP is what is causing those messages.

I'm not sure what HDCP is or how to resolve that, can you provide more info? Thanks!

So, here are the steps I tried before calling the "so-called" tech support.  I verified the TV on the latest version software.  I have unplugged the receiver box.  I have replaced the HDMI cable with a brand new 2.0 version.  I have checked to see if the other HDMI port works, it is fine, as my AppleTV box is also in that port and is working as expected.  I changed the screen resolution from 1080i to 480 (which the tv did not like).  That didn't work.  I finally called tech support.  

Their resolution was that my TV is too old.  Now, keep in mind I just purchased this TV 6 months ago and it has been working fine until this morning.  The receiver box shows it was manufactured in 9/2013!  My TV is a good 9-10 years newer that the receiver box, but somehow it's the problem all of a sudden? 

I did ask that they send me a new box, as I had taken the receiver box from my bedroom and connected it to the living room (where the issue was) and the bedroom box WORKS FINE!!).  She put me on hold for over 5 minutes to get approval, which I have the equipment insurance plan, then agreed to send it.  But, told me several times that she didn't think this would resolve the issue.  

For now, the 2015 receiver box from the bedroom is working fine on the 2022 TV that is in the living room.  I can't watch TV in the bedroom (1st world problems, right??) but at least the hubby is happy now.  So I will wait for my receiver to see what year it was manufactured, it seems I keep getting old, refurbished equipment that works for a year or so.  

That TV is certainly NOT "too old". Keep us posted when you receive the replacement box. 

I found it "strange" that the receiver box from the bedroom works just fine...which makes me, again, think it's an issue on their side.  I'm a retired reference librarian and have been researching this extensively before I posted for help and am still researching.  I was also a media specialist, so am a bit familiar with the moving parts of technology.  I will do almost anything before calling tech support for DirecTV...just saying.  

I have the exact same problem.  I don't understand why Directv can't send a technician out to fix this.

Because DTV can't fix HDCP problems.  DTV replaces things until it works again and will not replace non DTV equipment.

HDCP stands for Hollywood Dic*s Causing Problems.

It is a system design to encourage piracy. Moreover, HDCP standards keep changing. This often requires people to get new equipment all the way from the dish to the television in an attempt to make all the security protocols function. I've seen people throw away perfectly good $6,000 flat-screen TVs in a desperate attempt to get things working. In some cases, there are certain HDMI "adapters" that might help you. Look on eBay or elsewhere for possible solutions with the evil HDCP.

If you hate it, you are not alone. Everyone else except electronic manufacturers also hated.
