For freesat advice on this error
I wonder if any of you can help.
Had my box now a couple of years with very little issues. However, recently, when watching the TV upstairs, the screen is fine when I first switch it on and the the box goes black and with the message ' HDCP not valid. AV blocked.
You can hear the sound but there is no picture. If I switch the box off and then on again the picture comes back but then disappears again after a few seconds.
If I switch the box off at the wall it appears to fix it, but by tomorrow the problem appears again.
I've recently updated my software to the new trial version UKSFAA 3.00.11. Not sure if this has anything to do with it but the problem appeared to occur post the software update.
Any ideas how to fix?
