I have a Yamaha RX-V373 receiver connected to a Samsung LN46C530 via HDMI. Both are controlled by a Harmony One.
I am having problems controlling the receiver with the remote. When the TV is on, the receiver will only take commands intermittently. For example, I have to keep pressing the volume button for 3 - 5 seconds until the receiver finally picks up one of the button presses. With the TV turned off, the receiver takes commands just fine.
I have HDMI control turned off on the receiver and Anynet and CEC control turned off on the TV.
Any ideas on how to fix this?
