HT-R980 HDMI sync issue. Help!

I have an HT-R980 that I have connected to a Optoma HD20 with a 35ft HDMI cable. The 2 HDMI inputs are a cable box and a PS3. For almost a year things have been working fine, until 2 weeks ago. For some reason it seems like the signal isn't syncing between the reciever and the projector. When I turn on the projector, PS3 and reciever the screen shows searching.... then flashes 1960 x 1080 60HZ then blinks and then shows No Signal, then repeats the same loops over and over again. Occasionally, the sounds will come through, but no picture. If I try the cable signal I get a similar result: 1960 x 1080 30HZ and eventually a picture shows, but no sound.

Everything used to work fine. Sound, picture, everything. I could switch between inputs without a problem. Now, I canoot get consistent signals to be processed. I have tried to inplug everything. Power, cables, and still similar results.

Is there a way to force sync the HDMI signals between the source, reciever and display? I have not tried a factory reset, but I would like to not have to do that if I can avoid it. Any help would be appreciated.
