DVD wont play

Check a CD. If it plays, the Optical Pickup for the DVD is worn out and will need to be replaced.
If you are interested in having your LG repaired, please look to my website at audioserviceclinic.com. Thank you.

When you say play DVDs you mean watch DVD movies? Assuming the drive is not broken you need to use the DVD app. You could use VLC Player which you can download. It's an orange traffic cone icon.

usually this happens when lens cannot read the the disc. Due to few reason 1 Your disk is scratched 2 Your DVD lens is covered with dust 3 You need to replace DVD lens
Try another few CD/DVD to rectify whether there is any problem with dvd you are trying to play
if this error occurs on all the dvd you played then the most likely proble is with your DVD lens either its coverd with dust use Disk cleaner if not you got to replace a new DVD lense as per model

TROUBLESHOOTING

Troubleshooting specific errors
If you experience one of the following errors, follow the appropriate steps to resolve the error.

* There is no disc in the drive. Please insert a writable CD into drive.
This error can occur if the CD-R drive or CD-RW drive is not recognized as a recordable device. This error can also occur if the device driver has been corrupted. To resolve this issue, see Method 3 in the "General troubleshooting" section and Method 1 in the "Advanced troubleshooting" section.

* Drive not accessible, incorrect function
This error message typically occurs when you try to write to a CD-R or a CD-RW, and the Windows XP built-in disc recording feature does not recognize the CD drive as a recordable drive. This error message may also occur if specific third-party programs are installed. For more information about how to troubleshoot this error,

when you access the CD-ROM drive, the DVD-ROM drive, or the CD-RW drive
* Error Deleting File or Folder.
Cannot delete file name. Files on this CD-ROM drive are read-only. You cannot copy or move files over to this CD-ROM drive.

This error message can occur because individual files cannot be deleted from the CD-RW. You cannot use the CD disc recording feature of Windows XP for random-access storage while you are writing to disc.

Unable to read a CD-R or other recordable disc. Question: Unable to read a CD-R or other recordable disc.
Answer: Unfortunately this can be a difficult question to answer because of the amount of potential reasons for this issue to occur. Below is a listing of several steps and recommendations that can be taken to help identify the cause of the issue and/or resolve this issue.
Drivers Verify you have the latest drivers installed for the CD-R or recordable drive. There are numerous driver related issues that may cause a CD-R drive or other recordable to stop reading a CD-R disc. If you are running Microsoft Windows verify your drive is properly detected and listed in Device Manager with no conflicts or errors.
If Windows Device Manager detects an error on the drive or if it has other drives listed in Device Manager with errors on them remove the device from Device Manager and reboot the computer to let Windows re-initialize the drive.
If Windows shows no errors, the above steps did not resolve the issue, or you are running a different operating system check with the drive manufacturer for updated drivers. A listing of disc drivers can be found here.
CD-R disk Not all CD-R disks are compatible with all types and speeds of CD-R drives or other recordable drives (especially earlier CD-R drives). Verify the manufacturer gives 100% guarantee for supporting all drives and disc speeds, for example, TDK discs often give a 100% guarantee.
Pre-mastering/Mastering Software Pre-mastering software can sometimes produce incorrect tracks due to bugs. An incorrect ISO image could be generated, or incorrect sub header codes could be recorded in the case of Mode 2 discs. A good way to check whether the incompatibility problems lie with the originating software or with one of the other causes listed above is to test the same disc on several CD-ROM drives. If one drive is capable of reading the disc back correctly, chances are that the problem was not in the mastering, but is one or more of the other factors listed.
Disc is a recordable disc that the drive or player does not support Verify the drive supports the recordable media you are attempting to read. Below are some situations to watch out for.

• Old CD-ROM or early DVD drive - Some early CD-ROM drives and Gen 1 DVD drives (some of the first DVD drives released) do not support CD-R discs and/or CD-RW discs. Not only does this apply to computers but also home entertainment DVD players.
• CD-RW in CD-R or CD-ROM drive - CD-R drives are incapable of reading CD-RW drives. If you are using a CD-RW disc verify the drive is a CD-ROM or CD-R drive is capable of reading the disc.
• DVD recordable discs - If you have a DVD recordable disc and are unable to get it to read verify that the DVD drive is not a Gen 1 DVD drive and/or that it supports reading the DVD recordable media you are using. Additionally a standard CD-ROM, CD-R, CD-RW, etc drive is not able to read DVD discs.

Disc was created incorrectly Make sure you're creating the disc properly. For example, a common mistake users make when creating audio CD's that they can listen to in their computer, car, or home stereo is burning the MP3 files or other files directly to the CD as a Data disc and not an Audio disc. All this will do is burn the data files to the disc and not create an audio disc. This may allow you to listen to the audio files in the computer but will not allow you to listen to the music in the majority of other CD players unless they support MP3 format.
Disc or DVD contains media content not supported by the player Not all home entertainment DVD players are capable of supporting and playing all the different formats movie files and audio files are stored in. Make sure the format or codec of the movie or audio file you're saving to the CD or DVD is supported by the DVD player. If you're computer is capable of playing the files off the DVD but your home entertainment DVD player is not able to play the file it's likely you're encountering this issue.
Bad disc If after reading through the above recommendations you still continue to have the same issue it's possible that the disc is a bad disc. Try re-burning the disc and if possible try a different type of recordable disc.

Computer DVD Support

Click on the above link should get ya back up and going/Good Luck....Please dont for get to Vote.Thank you.

Try some factory CD and DVDs and just try to get them to open in Windows (not play in a media player program). If you get errors on every disc you try, it may be your CD/DVD hardware packing in.

If it reads some CDs or DVDs and not others, particularly media discs, you may be having software driver problems, otherwise, it is likely hardware.

Try inserting the disc and spinning it up while resting the laptop on its side, or even upside down. If it reads sideways or upside down, the CD/DVD reader hardware has gone and cannot probably be prepared (this is a symptom of physical controller failure and is ot fixable by normal means).

Good luck...

When you say it won?t read are you trying to play commercial DVD movies or read DVD data disks? If you're trying to play movies then you need a couple of things the first being some type of player program. Real player works as does Windows media player but usually DVD drives come with a striped down version of PowerDVD or WinDVD. If you in fact have a player installed and when a DVD is inserted in your drive it doesn't play it may not be configured to automatically play DVDs. Try opening your player program and trying to manually play your DVD. Let us know if you have any success or if you need more assisted. If you do let us know what player program and operating system you have and any error messages that may appear.

those kinda players wont play DVD rom disks and certain ones that are made up. DVD-RAM or ROM wont work. Try blowing inside the player for any dust. if it still doesnt work its the maufacters problem. The player will play CD-G audio only, not graphics The ability to play back DVD-R, DVD-RW, DVD+R, DVD+RW, CD-R, CD-RW, and CD-Jpeg discs may depend on recording conditions.
