i got a nice tv for HD yesterday. but im having issues with the hdmi. it doesnt work. i know icould bring it back but im lazy, and im loooking for answers here first.

the cable boxtells me that it doesnt support hdcp and i need to use the green blue red cables. but it does, and its suposed to. i called phillips and the guy had me look in the tech menu it says that the KEY (HDCP) - is INVALID .

they also said they would fix it for free, but im looking to see if anyone has any knowledge of this problem, so i know what im getting at here.

Have you tried turning on each equipment in different sequence? Sometimes the HDCP handshake only works when one component is turned on first.
