In this scenario, HDMI works properly when making a direct connection between your source and TV. When you add an AV receiver, switcher or other device between your source and your TV, it stops working.

Your cables and, surprisingly, your AV receiver aren’t to blame. The issue is with your source component (BD/DVD player, etc).

Problem: The source component did not send a ‘repeat’ code in front of its HDCP handshake code. As a result, the AV receiver wasn’t directed to pass the HDCP code to your TV. No HDCP handshake occurred between your DVD player and TV, no signal reached the TV.

Solution: Consider purchasing products that have guaranteed compatibility, such as those that are Simplay Labs HD certified. Another option is to connect with component video, supporting 720p/1080i video. For high-resolution surround sound, connect with digital audio cables.
