Question about Denon DVD-3910 DVD Player

1 Answer

Denon 3910 won't load some dvds/cds and vibrates while trying.."disc error"!

Hi, guys My Denon 3910 is killing me softly...
It all began with cds: taking longer to load, not starting at the beggining or failing to load and displaying all zeros...DVDs began to have extended load times, too. Progressed to: 1) vibrating while trying to load some new DVDs, failing and displaying either "stop" or all zeros. I finally tried a "Fellowes DVD Lens Cleaner " but it would only play the disc's main page and then completely stop, offering "disc error". This did help to allow for the playing of discs that previously would not, but not for long! I live in New York and seek a good repair shop and /or advice.
thanks, Mike.

Re: Denon 3910 won't load some dvds/cds and vibrates...

I have the Denon 2900 (about 4 years of use) and until recently, suffered from the same (growing) problem. CD's were very difficult to start/read. I recently found advice which I tried and was succesful with. It was manually cleaning the laserlens. I took away the outer housing by unscrewing all off the on top (6), side (4) and the back (2) bolts. After that I took out the top plate of the laserunit which took two very little screws taking out. Now you are looking at the cd-tray with the lens. Take a very soft and clean cloth and moisten it a little bit with clean water (be very carefull with the moistening, don't allow any waterdrop to come out of the cloth into the laserlens while cleaning! Carefully clean the lens and dry it with a dry part of the same cloth. Replace the top plate and the outer housing and the player will recognize the discs like it's new again. Good luck!

My Onkyo DV-C600 will not Load neither DVDs or CDs. It keeps flashing LOADING or Disc Error.

try cleaning the optics, with alcohol swab, if this dos not help you will need to replace the laser assembly. or and have further diagnostics performed on your unit.

DVD tray makes noise when it rotates

This noise can be casued by two things:

1) The tray is not completely in the loaded position and the "clamper" is rubbing. Replace the loading belt and the loading sequence will complete and the noise should stop.

2) The "CD table" that is part of the spindle motor assembly has slipped a bit. This will make the CD/DVD ride too low and strike the lower tray support. This will require that the table be "re-aligned" to the proper height which may not be possible on your model without special measurement equipment. The height is critical to proper operation of the unit.

Try replacing the load belt first and report your results.

I just doesn't load/read CD's.

I had the same problems with my four year Denon DVD-3910 and the only solution to it was to replace the laser unit with a new one.

There are some repair service on EBay that offer new laser units for only about 50 € and are also willing to change the laser unit for an extra charge of just 30 €.

After this replacement your Denon DVD-3910 will work fine again.

Mizuda dvd player wont read dvds


A couple of things To try.

1:) The DVD Player May be Region encoded, can only play certain region Dvds. ** Try different Disks**

2:) The Disk May Be Dirty-Scratched ( Towards The Centre )
** Clean The Disk With A Soft Lint-Free Cloth**

3:) The Laser Head may have a speck of dust or debris on it.
** Try a Laser Cleaning CD**

Hope this works For You.

Player does not recognize or play CDs

Thats how some manufacturers sell there replacement parts as they come into the country assembled. it cost let to import but more for us. i once needed a spindle motor for a unit, no replacement except the manufacturer part. Had to buy entire laser assy and thats what they bare selling you too. If you already tryed to manualy clean the lens, look on the side of the laser pick-up. it might be made by sony or a popular manufacturer go by the number printed on the label on the side or bottom of the laser assy unit itself. Good Luck
