Been There, Done That

If I turn the pj off, the sound returns from the AVR to the speakers. It seems the pj is not detecting the input and is cutting off the sound. So, I unplugged the HDMI output from the back of the AVR and plugged it directly into a source (the Roku) and voila, video displays through the PJ. So, Im thinking my Pioneer AVR's HDMI output crapped out on me after approx 5 years of use. Any thoughts are greatly appreciated.
Unless you've added some new equipment to the "chain", it's a pretty good chance that the HDMI board is the problem. By "adding new equipment to the chain" I mean mixing video equipment with different "handshake" settings. For example, if you've got the projector set to 1080p, and the AVR set to 1080p, then you add something that is 720p or 1080i, it can disrupt how this AVR handles the different resolutions and "breaks the chain". The only workaround is to make sure all of your gear plus the Optoma are set to the same 1080p output. It is possible that the output setting on one component in the chain has accidentally set itself to a different output resolution. If you've checked and made certain this hasn't happened, then the "handshake" is not the issue. If that's the case, the HDMI board must be replaced. Likely it'll cost more to replace the board than to simply buy a new AVR.
