Hello, My name is XXXXX XXXXX X will be glad to assist you.
What is connected to the Yamaha for devices (DVD, Cable Box, PS3, etc.)?
Also, are they connected via HDMI?
Have you tried switching sources and is the error message still there?
Thanks for the reply.
Please shut down the cable box and Yamaha. Unplug them both from AC power for 5 minutes. During this time disconnect and reconnect the HDMI cable from both devices. Then plug in the cable box and the receiver. Turn on and let it reboot. Then power on the Yamaha. This in most cases resets the Decoder OFF warning on Yamaha units.
If you need further assistance, let me know.
The only other thing you can try, would be to connect a DVD or Blu Ray player into the same jack that the Cable Box is plugged into, and see if you get the same issue. It is possible that the Cable box itself may be faulty. I would suggest trying this initially beyond calling for service on the Yamaha.
This does in fact indicate that the Yamaha is in need of service. Resetting the HDMI cable, trying different components and also trying to run the processor "STRAIGHT" instead of the unit attempting to Decode the HDMI signal is all one can do on a user level.
Unfortunately there is no sequence of buttons or reset you can perform to get the set working again.
You can use the link below to locate a Yamaha service center to rectify the problem.
Then the issue, as stated above is that unit IS in need of service. I cannot repair the unit from where I'm at, we can only perform settings and component level testing to determine where in fact the problem lies.
