Dvd and cd's will not read on player - Denon DVD-2910 DVD Player

Richard: This is what EHow.com said: "

Turn on the DVD player. It generally takes a few seconds to get going. Take out the DVD if there's one in the drive already.

2 Make sure the disc isn't scratched or dirty. Use a soft rag to clean the disc if you see any smudges. Insert the CD into the DVD player's disc drive and close it.

3 Press the "Play" button on the DVD player or remote control. Some DVD players will begin reading the disc automatically. Pushing the button works just as well.

4 Use the "Scene Selection" buttons on your remote to select a track. Some DVD players have odd ways of ordering the buttons on the remote. You might have to play around a bit before you find all the right buttons to work the CD playing function of your machine.

5 Crank it up and enjoy your music. The DVD player will act just like a CD player and play the tracks of the CD through the TV.

Check for scratches on the disk surface - these can inhibit the player from reading a disk correctly.

Some players will read olny certain type(s) of disks. This is an issue mostly for disks created on a computer, not those that are prerecorded and available for purchase or rental that contain movies and music.

As stated above, dIsks created on a home computer may not always be readable on a home player. Re-writeable and recordable types that are not listed as being compatible will not work. Check your manual to see which types are acceptable and not. DVD types are: DVD-R, DVD-RW, DVD+R, DVD+RW and DVD-RAM CD Types are CD-R, CD+R and CR-RW. Older home CD and DVD players generally work with "-R" types and the newer players with both "-R" & "+R" types. "-RW" and "-RAM" types are the least likely to be readable in home players.

Additionally, most players require that disks created on a home computer be "finalized". This is an extra step that isn't required by most CD / DVD drives in computers. Just because it works in your computer doesn't mean it will work in your home player. If you're using compatible media and still not able to read disks, check your CD / DVD recording software options to enable finalization.

Good luck!

The only discs that a DVD player is guaranteed to read are DVD discs. Support for CD-ROM, CD-R, and CD-RW may be included, but is by no means guaranteed.

CD-R was designed to be read by an infrared 780nm laser. DVD uses a visible red 635nm or 650nm laser, which aren't reflected sufficiently by the organic dye polymers used in CD-R media. As a result, many DVD players can't read CD-R media. Some DVD players come with two lasers so that they can read CD-R.

But as I have already stated that Most DVDs today have the tendency of playing CDs. So if your DVD player is new then it must have that support. Have a look at the quality of your CDs also.

if it doesnt read any kind of dvd discs at all it only means you have been rip off. It happened to my sony dvd player that I bought from this website. I tested it and it only reads cd or audio cd. Good thing my couzin fixes electronics, He checked on the lens and it turned out that the lens has been replaced with an audio/cd lens like the one we use for our car stereo. Too bad!!!

Hello,
This DVD player unfortunately does not support most of the Copied DVD /CDs.
it works stemless with only genuine / original CD and DVDs..
If your DVD or CD originallly recorded by manufacturers but still can not read ,
than I recommend you to obtain and apply it to clean your laser eye of the DVD player.
Hope it will solve your problem.
Please remembr to vote me too..
Regards
Compatible disc formats: DVD, CD, CDR, CDRW, Video CD

Some dvd have a multiple laser function for dvd and use a single laser for cd. common fault on not reading dvd is dirt on laser or fault on multiple laser that cannot read dvd. If cleaning doesnt help only repair tech can fix. Just check that the dvd is working in another dvd player to ensure it is not disk

EITHER CLEAN or replace THE OPTICAL LENS , try first to clean it directly with a DRY Q-tip ,and test player again. if it doesnt read , then replace the optical lens, hope this helps , AJ

No-disc errors are usually caused when the DVD or the laser-lens pickup has become dirty and causes the DVD player to not be able to read the DVD.

i have LG DVd writer combo drive. it reads cd but does not read dvd.

Just like with CD players...not all Players will read the CD-RW format..but they will read the CD-R's. Check your manual to see if your DVD-Player is compatible with DVD+RW formats.
