I have a problem with intermittent video dropouts on my system, which I believe is being caused by my Yamaha DSPAX763.
I presently have a Panasonic BD35 blu-ray player and an Xbox360 connected to the 2 HDMI inputs of the AX763. Both are set to output 1080p.
The HDMI output of the AX763 is connected to a Samsung LCD.
The video dropouts are random, and only occur when 'true' high definition content is being input to the AX763 (e.g. Blu-ray or Xbox360). Standard definition DVD upscaled by the Panasonic BD35 does not exhibit the problem. I've watched hours of upscaled DVD with no issues.
During the dropouts the audio is unaffected.
The dropouts take the form of a jumping, distorted picture, which after a few seconds results in the Samsung TV displaying "No Signal" or "Mode not Supported". Sometimes it happens frequently (every minute or so), at other times the signal is perfect for hours. Sometimes it's as soon as I switch the system on, at other times only after an hour or more.
Sometimes the picture will re-appear after a few seconds. Other times I have to change the Amp or TV input or power-cycle the AX763 to get it back.
As the issue occurs with both the Xbox360 and the BD35, the issue must lie with either the AX763, TV, or HDMI cable that connects the two. I have tried connecting the BD35 directly to the TV using this HDMI cable, and the problem has not occurred (in the relatively limited time I've been able to run it like this). This suggests that the issue is with the AX763.
I intend to call Yamaha support to see if they can assist, but I wondered if anyone else had encountered this problem, or could suggest anything else I can/should test?
I have noticed that when switching between HDMI inputs on the AX763 the HDMI and PCM indicators flash on and off for a few seconds before it locks on and the image appears - is this normal for an AX763?
