So the last month or so we have been having a strange HDMI sync issue with our HR34. We have our HR34 attached to an Onkyo 607 receiver. We can watch TV with no issues but when we turn the Receiver off and leave the HR34 on and leave for an extended period of time(say several hours/ a day), when we turn everything back on, we get a black screen with no sound or anything. We have to continually turn the Onkyo On/Off or unplug/replug the HDMI cable in and it will display everything properly and we are fine. It seems the HR34 no longer syncing properly with the Onkyo. I have changed HDMI cables, changed the HDMI port that the HR34 uses on the Onkyo receiver, but it doesn't change anything. We have ZERO issues with any of the other devices attached to the Onkyo. We have a PS3, XBox 360 and a PCH-A210 attached to it and everything is fine HDMI wise. This seems exclusive to the HR34 and the Onkyo. What is weird is, this does NOT happen if after turning the receiver off, we turn it back on in a lesser time, say a half hour or less. It works fine. It's only when it has been off for an extended amount of time. I have Power Saving turned OFF on the HR34, but I'm not sure that prevents the screen saver from coming up after a long period of time. I am wondering if that switch to the screen saver mode is what is preventing a proper sync the next time the receiver is turned on. Any ideas to try? I see there is new firmware that was just released(we are on 744 now) so maybe that will help things.
