What should I do if I see a “HDCP Error Detected” message
This topic may have been posted before, but specific to me, I can't find an answer. I have a Roku 3, and a Panasonic Viera LCD 37" TV from about 2009. Have never had any problems with Roku. Today, I added the Apple channel, and it worked when I set it up, but when I turned the TV back on later, I got the HDCP error detected message. I followed the instructions for unplugging the HDMI cable from both the TV and Roku device, plugged it back into both, and I still get the same screen. So, I can't even delete the Apple channel to see if that's the problem. Any suggestions?
Re: What should I do if I see a “HDCP Error Detected” message
I wouldn't expect the ATV channel to be an issue if it's not even running. HDCP errors tend to be one of three things. The HDMI ports have dirt/dust in them, blocking the connection, the HDMI cable has failed, or one of the devices has a hardware failure. Your TV is pretty old, as is your Roku 3. There are two versions of the Roku 3, one released in 2013 and the other in 2015. The older one is no longer supported, but since you could install ATV it's likely the newer one.
So, three things to try: using a different HDMI cable, after ensuring the ports are all clean, connecting the Roku to a different TV as a test, and connecting something else to your TV to see if the port still works.
If the Roku doesn't work on a different TV, it's likely suffered some sort of hardware failure, and replacement is the only option. If it works fine on a different TV, then the Roku isn't the issue, and you have to look elsewhere.
