The loading mechanism has the trouble. The inserted CD or DVD does not engage into the laser assembly unit properly. It may be due some fault with its loading motor or loading belt. Check these.

It won't press the button even though the power is on

Since you don't indicate what you mean by "won't work", let me provide a few possibilities:

1) You close the door and you can hear the DVD spin, but no reaction on the screen other than some type of "loading" message. This indicates that the optics are attempting to read the DVD but are having difficulties. The operation may ultimately be successful and the DVD may start, but the movie will be unwatchable because of freezes etc. In this case, try cleaning the lens using a cotton swab and alcohol. A dirty lens can cause this.

2) You close the lid and do not hear the DVD spin. In this case, the optics can not even determine that a disc is in the machine. Again attempt to clean the lens. If that fails to at least cause the disc to spin, the optics have failed and need to be replaced.

3) Try a music CD. If that plays OK, but a DVD does not, then the optics are defective and need to be replaced. DVDs require a more powerful laser and will typically fail sooner than CD levels.

Hope this helps,

When you try to play a DVD game on Xbox 360 it tries to play as a movie?

c on your Xbox 360 console, you may receive an error message. This article presents step-by-step guidance to help you determine whether your disc is playable.
SYMPTOMS When you try to play a disc, you may receive the following error message: Can’t read this DVD.
CAUSE The DVD or game disc may be dirty or damaged. Because the console cannot read the disc well, it may even mistake a game disc for a DVD and report this error. If this problem occurs with multiple discs, even clean and undamaged discs, there may be a problem with your Xbox 360 console.
Note If you receive a different error message, such as one of the following messages, the problem is a different problem:
Error message 1 Can't play DVD. Wrong region code. Error message 2 Can’t play DVD. Family settings restrict playback of this DVD. If you receive one of these error messages, see the corresponding Knowledge Base article: 907620 While attempting to play a standard DVD movie using your Xbox 360 console, you receive the error message: "Can't play DVD. Wrong region code" 908645 While attempting to play a DVD movie using your Xbox 360 console, you receive the error message: "Can’t play DVD. Family settings restrict playback of this DVD"
THINGS TO TRY Here are some things that you can do to try to fix the problem or to determine what caused it.
Determine whether the disc is dirty or damaged Discs that are smudged, scratched, or otherwise damaged cannot be read by the Xbox 360 console. You will want to examine the disc to see whether it has smudges, scratches, or other damage. To do this, follow these steps: 1. Examine the disc for dirt or damage: a. Pick up the disc by its edges. Do not touch the top or bottom surface. b. Examine the shiny side of the disc to make sure that the disc is clean and has no damage.
NoteScratches that follow the curve of the disc are very damaging and prevent a disc from being read. If your disc has even one of these kinds of scratches, the disc is damaged, and you will no longer be able to play it. If this is the case, see step 4. 2. If the disc is dirty, clean the disc by hand: • Use a soft, clean, dry, chemical-free cloth to clean the disc. • Lightly wipe from the center of the disc outward. 3. After you clean the disc, try to load it in the Xbox 360 console. If the disc still will not load or you receive the same error message, the disc is damaged, and you will no longer be able to play it. If this is the case, see step 4. 4. If the disc is damaged, do one of the following: • Because DVD discs are not game discs and the disc was damaged because of misuse of some type, such as not storing the disc in its case, the only thing that you can do is buy a new one. • If you feel that the disc was damaged by the Xbox 360 console in some way, please contact Xbox Customer Support. To do this, please visit the following Microsoft Web site:

I don't know if my first REQUEST for Assistance was received, at any case, I REQUESTED to find WHY my GO.VIDEO COMBO Player is NOT READING any of my blank DVD DISC( SONY, IMATION, MEMOREX, DVD+R ), IT KEEP...

If there is nothing on the disc, it will read, "no disc". It will only read and/or identify discs with media loaded or burned onto it. Your unit is a player, not a DVD+R (recorder). Can record VHS, but not discs.

I have thinkpad T61 it was loaded with vista. It

what kind of media are you loading? is this a DVD or a program disc? If this is a DVD disc, try loading a music CD or other type of disc to see if it is recognized. If so, its possible your PC DVD is unable to recognize that specifc type of DVD. Try other DVD's which you know worked before using Vista. Even though your machine says the device is working properly, check the Lenovo website for updated drivers for the DVD and the board chipset. Let me know if updating the drivers does not work. Meanwhile, I'll see if I can find out any more information from Lenovo.

My NAD cd/dvd T550 displays NO DISC.

I have the same problem. When I insert a disk, my NAD T 550 DVD player displays 'No Disc'. It started with new disks while still reading older disks, but at some time it stopped recognizing any disk. Did you receive any suggestion yet or has anyone a suggestion?
