Blacking out

[Earfull]

I have:

Denon AVR-3805 Receiver
Panny S77 DVD player
Panny AE900U projector

Lately, on some DVD movies, the picture will suddenly go black for about 1 or 2 seconds then return to normal. It will do this a number of times, about 30 seconds apart, then the problem disappears. I think it only does this in the very early portion of the movie.

Where should I suspect the problem is?

Cheers.

How is the video chain connected?

DVD to receiver to display, or DVD directly to display?

What type connectons are you using from one to the other? Componsnt, HDMI, and from which to which?

It's a 35' HDMI cable (from Monoprice). DVD player to PJ.

I forget the guage, but it's a fatty, 7/16" dia.

Unfortunately outside diameter doesn't tell us what ga the wire is. 35 ft is long but you are indicating it is happening lately, not from day one with that long cable? Connections still tight?

How many hours on that projector bulb?

I'd have to turn it on to find the hour usage, but it's not too much.
Yes, it's been happening only lately, and occasionally.
I will check connections.

Thanks!

BTW: Where's the be$t source for bulbs for this unit? (Western Canada)

If the bulb is relatively new and connections are secure, not sure of a good cause. A cold joint in the wire would do it but not just one wire, don't think.

Also, I guess even a few new bulbs go bad well before their time is up

If you know the bulb number, should be in the manual as it is a user replacement item, try Google.

One more experiment for you, if not difficult. Try to remove the DVD player and hook it up to another TV and see if this happens. I guess it could be the player having an issue? You probably want to use a short HDMI cable, unless you can move a TV to the end of that 35ft cable

When these bulbs fail, don't they just completely fail/burn-out? Is it even possible for this problem to be the bulb?

Anything is possible. Time to do some troubleshooting, one step ata time.

First off, I'm assuming this is a new problem. It's didn't start on day one.

Second, since it's a direct link from the DVD to the PJ, you can rule out the receiver. That's one step accomplished.

Now, we have to try to isolate the culprit and the only way to do that is by process of elimination.

Do you have any other sources feeding the PJ? If so, does it black out with them? If so, then it pretty much points to the PJ. If not, then it's back to the drawing board.

I'd next try to swap out, or at least readjust, the HDMI cable. As Mtry suggested, the length and solidarity of the connections may be an issue. I know my HDMI sometimes gets loosened by the gremlins with the tiniest shift and I have to reinsert it, at least on the DVD side.

If it ain't the cable, and it ain't the PJ, that leaves only one possibility and it may be time to "test run" a new unit. Pay by CC, keep all materials and keep it pristine. If the problem goes away you know it's the old unit and you've already got a replacement. If not, then pack it up, take it back and get the charge reversed.

Other than that, I'm outta ideas.

Thanks Mark,

There's just a single component cable to the projector from the receiver for the PS2. It rarely gets used so I don't know if the problem occurs with it.

Is my problem something that you've ever heard of being due to the DVD player or projector? If not then it's probably a cable connection.


Thanks

Since I haven't seen all bulb failures or possible method of dying I have no idea if all bulbs just go dark all at once, or this is a prelude to a failure soon.
But, as mark indicated it is a process of elimination and some bulbs do fail well before their time, on the fringes of the Bell Curve

I have personally seen an s-video cable cold joint cause dimming of the picture. Hard to know for sure one culprit without testing and elimination of parts that could be at fault, especially since this is a new problem. A video card in the player is going bad? I had one with loss of memory, aspect ratios jumping, etc. Circuit boards and computer like programs, who knows for sure. Not a straight cut to the cause, not by me, anyhow.

Since your probelm is with the video alone, and your
HDMI is run directly from the DVD to the PJ, I've ignored anything except that path.

You might try a direct run from the PS2 to the PJ for that second source test. If it still does it, you may have found the culprit.

Of course, there's always the possible test scenario of replacing the HDMI video run with component, S-video, or even yellow-jack composite video runs. Dunno the max lengths for those, though.

Your best bet now is to try to isolate the problem, one item at a time.

I know this is an old thread, but having experimented with numerous things I have found that it is the Projector which requires warming up in order to not have the short, intermitent black-outs.

Why would that be?
