Screen does not support HDCP - HELP

[Arnie McKay]

Hello, my Sky Q box has been working fine for a while and all of a sudden, I have started getting an error message on my Samsung TV saying "This screen does not support HDCP. Try reconnecting your HDMI cable, or use a different screen". 

After a few times trying to turn everything on & off it will start to work however over the past week, nothing I do fixes the issue.

The TV is on the wall, and I put 3x HDMI cables in the back. All cables have been tried with no success including the Sky HDMI lead itself. I contacted Sky who recommended I tried the Q box on another TV so I done this using a smaller Samsung which I have at home. The Sky Q box worked perfectly with no issues at all, therefore it has to be my main TV which has a problem. The TV itself is a SAMSUNG UE58RU7100KXXU which was purchased in 2020. 

As a last resort I have ordered a HDMI splitter as I read online this might help. If that fails, I will likely need to buy a new TV....and it definitely won't be Samsung 😞 

If anybody can help that would be hugely appreciated!! This has been working perfect for over 3 years so I don't understand how it can just all of a sudden fail like this. Note, I can still get the smart functions of the TV to work and my amazon firestick also still works fine, so the HDMI ports are OK.

Hi @Arnie McKay 

Sorry you have had issues with Samsung and the Q Box.   I have the same set up myself but have  had not had many problems.  Sometimes removing the power cable for 30 seconds sorts it.   Just checking that you have UHD colour or Input Signal Plus turned on for the appropriate port. Do you have latest  TV firmware  1406.3  (may be 1406 on Tv) https://www.samsung.com/uk/support/model/UE58RU7100KXXU/  

Best to  reboot Q Box and Tv at same time, though you may already have done this.  changing HDMI cable obviously can sometimes work , I had this issue once but changing cable fixed it for me.  Worth going into Q system go to Settings-Audio Visual-Picture Resolution, set Resolution for UHD  and Find it For Me to set this up again.   Obviously  some have more problems than others and appreciate the frustrations.        Some customers have found that issues happen  less often if they change the ECO setting to None but would still need to put the Box into standby manually. Changing HDMI control option has had an effect for some customers too.

However there was information a  little while ago  that there is an compatibility problem with the One Connect Box   and whilst they do work ok together the tuning of the distribution of the One Connect Box (q part of it) needs resetting at times.  (if this is applicable)

UPDATE: So last night I took my TV off the wall so I could play about with the HDMI cables/ports. I tried the exact same cable that worked perfectly fine for my smaller TV and the only HDMI port which worked was HDMI 1. I used to have my amazon firestick in this port so I've re-located that into HDMI 3. I then plugged one of the original HDMI cables (located in the wall) into HDMI port 1 and back into the Sky Q box and it has been working perfectly fine. Even this morning, no problems at all, everything came back on as normal. 

Very strange but it seems just changing the HDMI port has worked. I tried the other ports again and these also started to work!!! So I have no idea what or how it has cured the issue but I'm not complaining, hopefully that is the end of it all. 

I also changed my Sky Q box setting to UHD, so perhaps that made a difference.

Glad you appear to have a solution
