OK I'll do my best to explain this and it might get it bit long... Here's the setup running through HDMI:
HD-A35 --> Monoprice 4 port HDMI switch --> Onkyo TX-SR605 --> Samsung HL67A750
I have a PS3 and 360 that run HDMI just like the HD-A35 through the same hardware with zero issues. I've also got a PC using the audio/VGA TV connection, and a cable box using HDMI directly to the TV (video to TV, audio to Onkyo) with no issues. Also a Nintendo Wii running component/audio through the Onkyo to TV with no issues.
About two weeks ago I was watching a regular DVD through the HD-A35 when the picture would cut out for a second or two (the audio was fine) then come back. The TV acted like there was a split second source change were it would go black, then show the image with the "new" resolution and hz. Then it did it again, this time with both audio and video cutting out. Then I noticed randomly that the audio would cut for a split second randomly a few times, then the video again... etc, etc.
I power cycled all the devices and it seemd OK for the rest of that DVD. The next day I tried watching something else and it started again. This time I power cycled everything one at a time to see if I could figure out the problem area... when I did the Onkyo it was fixed again. Until the next day... this time I tired the Onkyo first but the problem still happened. So I started other devices again but this time nothing worked.
I then tried a new HDMI cable and it was fixed again... until the next day... and the same issues started again... this time it was fixed with just power cycling the TV.
At this point I think I had firmware 2.0 on my HD-A35... so I did an internet firmware update two days ago (so I assume I got v4.0 now) to see if that would help... didn't help a thing. I'm also running the newest available firmware for my TV so there's nothing I can try there.
Today when I was looking more close at the picture I was getting I found random white pixles poping up all over the TV screen (I call them sparkles)... I see this same thing sometimes on my PS3 after it switches resolutions, but that goes away on it's own.
At this point I haven't tested an HD-DVD disc and have only been trying to play regular DVDs... I guess it's also possible I simply have two bad HDMI cables... or maybe the specific port on my switch box is having issues???
This seems like an HDCP handshake issue.... but I'm not sure why it would start out of the blue after months of being fine.
Any thoughts or suggestions??
I do have an HD-A2, but of course that doesn't output 1080p so I'm a bit worried about my HD-A35 dying as I'm unsure where I could get a replacement (I haven't priced the bay yet)
(sorry about any spelling or grammar issues... I'm a bit tired)
