Found a really good explanation on another sight for HDMI handshake issues.
Digital components connected via HDMI use a copy protection system called HDCP. When components are switched on or connected, they talk to each other via the HDMI cable, verify the HDCP and then allow the picture to be displayed. This verification is commonly referred to as the "HDMI handshake."
With my home-theater system, the processor says "need HDCP monitor" when the handshake isn't established, and I find myself staring at a screen that either flickers or is solid blue or black.
Typically, changing inputs is all that is needed to establish the HDMI handshake.
If you want to watch your cable box, change the input on your receiver to something else and change it back to the cable box. You can change it to any input, because all you are doing is breaking the connection between the cable box and the receiver and re-establishing it. This should get things working for you right away.
Your remote might be part of the problem. Many universal remotes have an option to turn all the components on at once with a single press of a button. The most reliable way to establish a good HDMI handshake is to turn on the television first and let it boot up, then turn on the receiver, then turn on the cable box and Blu-ray player.
