Re: Problems with ARC on MU9000


The ARC on my TV is now working again. I am not 100% sure what fixed it but the samsung tech replaced the main board (still had the problem), They then replaced the OneConnectBox (still had the problem), and then the tech called a samsung support number and they instructed us to do the steps below. I'm not sure if it was a specific one of these things that did it or if all three were required but I would suggested trying the steps below but it does not require and replacement parts.


Steps the Samsung support tech (on the phone) had us perform.

1. Turn off the Anynet+(HDMI-CEC) in the settings on the TV.

2. Turn off the CEC on the AV REceiver.

3. Power off both devices.

4. Turn on the Anynet+(HDMI-CEC) in the settings on the TV.

5. Turn on the CEC on the AV Reciever.
