Denon DVD-A1UD/DVD-A1UDCI Blu-Ray/DVD/SACD/DVD-A/ Universal Player - Page 118

My A1UD is exhibiting this same disc tray problem, but maybe even more so. It has difficulty when opening, and seems to struggle when closing as well. After a few open/close cycles, it smooths out a little. But after a movie is in an the tray has been closed for a good 2 hours or more, it once again has a a tough time trying to slide out. I'm thinking something is drying out, and that it needs to be re-lubricated.

I called Denon about this, and the person I spoke with was absolutely no help at all. He told me to contact a service center. Ok, I've had my A1UD for over about four years now, so it's obviously out of warranty. So if I decide to take the top off and take a look at what is causing the sticking of the tray, maybe I can do something. Other than the tray issue, my A1 is functionally perfect, and all the Blu-ray's I've played in it play flawlessly.

I continue to have freezing problems with my A1 playing bluray disc's from Blockbuster. Yet it plays all the bluray discs that I own with no problems. My 3800 bluray player plays the Blockbuster disc's w/o freezing. What does this mean; is it that that my A1 is very sensitive to disc's that are not completely clean? I got my A1 back from repair about 6 months ago and they replaced the bluray drive so I wouldn't think that's the problem. It might be time get a new player and just use the A1 for music which it seems to excel at and doesn't have problems with music disc's.

It is a sensitive player, that"s the truth.

After many years of flawless operation today I went to play a DVD-A disc and it would not play, the menu just said No Disc. I opened the tray and closed it again, no difference, the player doesn't see the disc. I put another disc in, same thing, then another, and another, .... out of all of my DVD-A's only 2 would play. No matter how many times I open and shut the tray for a DVD-A disc most are not recognized. I have had these discs for years and never had a problem in the past. I'm also experiencing the same issue on some SACD's and even noticed it on one DVD. I have far too many discs to test everything. So far Blu-rays have been loading without issue. I have unplugged the power cord and let the player sit for a while then re-tested, no difference. The firmware is up to date.

Any one have any ideas what might be going on?

Thanks

Oh dear - I have had a similar, if less drastic, experience recently when several new DVD-As would not play. Since they were new I assumed it might be the discs but a friend with an Ayre player had no difficulty. I too would be interested in suggestions of what might be happening and what might cure the problem.

One of the most likely culprits is the laser head that's used for everything but Blurays - there are most likely 2 laser heads in the player, which explains why Blurays are still working fine.

Thanks. That's definitely a possibility then. It occurred to me later this afternoon that within just the past few weeks is when I applied the most recent update. I wish I could remember when I last listened to a DVD-Audio disc, I know it couldn't be more then 3-4 months ago and whatever I played worked fine then and it wouldn't have been either of the 2 discs that still do play.

DJB of Poole, when did you start experiencing those issues and do you know if it was after the most recent update (assuming you update the firmware)?

gsr, do you have any DVD-Audio discs to try?

I do, but playing them in my Oppo won't tell you much . I don't own a DVD-A1UDCI.

Ah, gotcha

My firmware is up to date according to the machine. I am a UK user so there might be differences of course. I had this difficulty about two weeks ago when trying a couple of DVD-A discs I had been given to review. The situation was that some discs played and others did not but I have so few it was not very important to sort it out. The important stuff for me is the SACD and Blu-ray repertoire; these all play just fine. All the DVD-As played on a friend's Ayre Universal so it wasn't the discs themselves.

Others have noted that two lasers are used in the DVDA1. Is one for CD/DVD-V and the other for the hi-rez discs SACD/DVD-A/Blu-ray? If this is so then any problems I have experienced cannot be down to laser alignment because I regularly play discs from both groups.

There should be one laser for Bluray (blue) and another for everything else (red), AFAIK.
