My Denon DVD A1UD Universal player, central my hi-rez system, despite working OK, has never had the smoothest of disc drawers. As it opens and shuts it has always 'juddered' very slightly as if it needs lubricating. On other players I own, notably a very old Sony CDP502ESII, smooth running is achieved by polishing the rails with a clean lint free cloth. Lubrication is probably the last thing one should or could do of course. I'm scared to open up the Denon and in any case I suspect the drive is a separate sealed unit. Any suggestions anyone?
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.
