Dvd player is the only thing hooked to the receiver now, Getting all audio, through HDMI, Opt, PCM etc etc.
No video output at all from the rx-v661.
The large red letters on the front display, that read "HDMI" blink on and off.
Like it is trying to connect but not all the way. The audio comes through when nothing but the hdmi is connected from dvd to receiver, receiver to TV.
Handshake is not there, or barely. Maybe swap the amp out for a diff tester, or return it.
Tried diff cables of all sorts, just short of taking it all apart and rebuilding.
I can take the amp to work with me and test it there, diff TV, dvd, and cables. See what happens.
Other than that, I am kinda stumped. Maybe clean the connections on all cables and the hdmi input on the receiver.
