Denon DVD-1920 Problems ?

[Ssebu]

Hi all !
I've got problems with a Denon DVD-1920 I purchased some three weeks ago.
I'm running it through the component outputs.

The first problem is that, for certain DVDs, on scenes where there is a lot of movement (that is, when the bitrate becomes momentarily very high), the player will black out (the image is lost) until it can start reading normally again. This does not affect the audio. Also, this is only true when the de-interlacing is turned on. Turning it off removes the problem. This problem is repeatable, in that the same scene will always cause the blackout. And no, the disc is not dirty.

The second problem is that sometimes, the image will black out, but this is irregular: it does not seem to be caused by any scene in particular. Again, the sound still works. This problem is more alarming because it vaguely looks like an electrical problem, and when the image is lost, it can be a while before it comes back. The unit I original bought was returned to the store because of this problem, but my new unit still has it. It also sounds like an electrical problem, because when the image is lost, the TV makes a sound, as if it was shutting down. This is very weird. And FYI, I also changed the wires, the problem is still present.

The final problem is that, although the reviews are generally pretty good on the internet, I still find the de-interlacing to be somewhat problematic in that jaggies are still present.

Did anybody ever experience this too ? Any solutions ?

I think I found the solution to my first problem. Looks like my TV's video noise correction feature was acting up. However, I still haven't found the solution to the second problem.

Did anybody ever see such a behavior with a DVD player, where the image goes black when the bitrate goes up too much because the de-interlacer can't cope ?

And also, is it possible that the TV could still be acting up ? I think the signal coming in through component cables is analog, so I don't think it would be a digital problem ...

At this point (since you've tried different cables) I'd try the player, using known problematic software titles, on a different display. If it doesn't act up on a different display then it's either your unit.....or a power problem in your house (unlikely)

I have a similar issue with the 1920. Ocassionally, the image will be lost as if the signal was cut off. The TV goes black and then it comes back again. I cannot reproduce the problem at will. It's not the HDMI cable because I've tried two cables. There must be an electrical or firmware glitch in the player. I'll be contacting Denon to find out more.

Update -- I just got a Denon 2910, and it had the same dropout problem. Also, I got a Tosh SD-K850SU and hooked it up to the HDMI/720p and it has the same dropout issue. At 1hr 29min into "Narnia" it blanked out. Three DVD players can't have this same issue. It has to be my panny TH50PM50U acting up. I'll be scheduling a service tech for a house call. Maybe a faulty board is overheating.

BTW that Tosh only cost $79 at Costco -- well worth it if only for the purpose of aiding in diagnostics. I figured that maybe two Denons could both have a similar fault. Unlikely, but remotely possible. There's no way a third player from a completely different manufacturer could also exhibit the exact same malfunction symptom.

This may or may not help you, but I had a similar prob with my Denon 2200 and the Infocus X1 projector, where every now and then the X1 would loose the signal for a bit and then lock back onto it, again this was irregular. I found the answer when I played My AVIA disc with the IRE test patterns, the higher I went I would loose the picture. The answer was to turn the Sharpness down in the 2200 until I could play the 100IRE pattern without the X1 dropping the signal. Since then I've never had the Projector loose the signal.

I've seen this before too...

I've seen this on my stuff before too. I currently have an RCA DRC212 (that I am looking to replace anyway, it doesn't play my DVD re-writeables anymore) and an RCA tube TV connected through S-Video. Anytime there is a lot of action, or explosions or flashes of light in the movie, it looks like the signal gets lost, and the tv displays for just a split second the "Unusable Signal" message on the screen. I always thought that it was my player, because my very old Toshiba SD1600 never did that. But perhaps as MACCA350 said, it may be the sharpness of the player? Though I don't know if I could even do that on this old thing, nor do I know if it would even be worth trying to do at this point, since I am looking to replace it anyway. I will be putting up a new thread in a bit here to see what players that I have been looking at would be good to get.

Well I recently had time to bring my 1920 over to my uncle's place, who happens to have an HD TV I could try it on too. Surprisingly, the image DID NOT get lost at all on all the sequences I normally use to reproduce this (Nine Inch Nails' And All That Could Have Been). Looks like it was my HD TV acting up after all. Funny, I never thought there was some logic circuitry in my TV. This is a CRT projector after all, it should't need to do resolution modifications. Is there such a thing as the component signal being too hot for the TV ?

Also, another problem I have been experiencing recently with my 1920 is that every time I press the eject button on the front of the player, I get shocked. Pretty frustrating. Is there a design problem with the player where it is badly grounded ?

Ssebu, did the sharpness control help you sort out the second problem?
