HDMI problem or not?

post #1 of 7
Thread Starter 
A couple of weeks ago I connected an Oppo BDP-103 up to a marantz AV8801 pre/pro, then to my JVC Rs1 proj. Everything works fine (including motorola cable box), but whle watching Blu ray of "Saving private Ryan" I lost audio towards end of movie, but video was OK. I back tracked a chapter, then audio came back. Then last night while watching another Blu ray screen went blue for about 2 seconds (audio continued) then came back. I tried "SPR" last night where the audio dropped out; it was fine. These are the only 2 issues I've had in the 2 weeks i have had the new Oppo & marantz in the system.

My cables are all Blue Jeans, with a 30 ft. run to my proj. This isn't the latest Belden made HDMI cable from Blue Jeans, it's the chinese made one about 3-4 years old. No handshake issues, no sparklies or anything like that. Maybe i'm just overreacting, or does it sound like there's an issue somewhere?

Thanks!

It might be an (almost) break somewhere in the wire.

I had the same thing before where the screen would go pink or green or some other color for a few seconds and then go back to normal for a few weeks. It was the hdmi cord.

If something happens once, it's a glitch. When it happens again, it's a problem (unless we're talking about human-rated stuff, of course, when even one glitch is too many).

It looks like you are getting random bit errors that aren't too frequent. It could also be poorly written firmware. Here's how I would troubleshoot:

1) Check forums for similar instances with each of the components. I think we can rule out the RS1 since you had an audio glitch. I doubt the BDP-103 would have a problem with SPR, but you might check there. The first place I would start is with the AV8801 and see if anyone else has this problem. Also check to make sure you have the latest firmware in all three devices.

2) Get to a point where you can reproduce the problem when needed. That's going to be the hard part. Unfortunately, without knowing how to repeat, it's going to be hard to say you've solved the issue. But, see if you can come up with a way to reproduce the problem at will.

3) I'd try a different cable for the 30-footer. That is outside of the High Speed spec. So you are using a standard speed cable in a high speed situation. It should work for 1080p but you never know. So, I'd spend the $20 to try out a different cable.

4) Try the BDP-103 directly connected to the JVC projector. If it doesn't occur then, it narrows down the problem location.

Unfortunately, you're going to either need a lot of luck or patience. Waiting for an infrequent glitch to occur will likely add up to a lot of time troubleshooting.

Tricky one if it’s not repeatable.

Keep an eye on the AV8801 front panel when you lose audio – is it still indicating it is locked to an audio signal or not!

Is the AV8801 set to do any form of video processing or is it in bypass mode – and anything ‘daft’ like Deep Color enabled anywhere?

As Andy say ensure you have the latest FW loaded on all connected devices.

Good idea to keep track of the front panel on the 8801. All has been fine the last week or so, then last night I put on the Blu-ray of "Jurassic Park". Got no audio when movie started - to fix it I switched to the Spanish language track then back to English on the Oppo 103 pop up audio menu.
