The most common mechanical problems that can prevent a dvd player from playing or reading the discs

The most common mechanical problems that can prevent a dvd player from playing or reading the discs are the following:

1. The spindle motor not functioning properly (this is by far the most common, if the spindle motor is not spinning the discs then the optical lens can not read them). For the most part it is an cheap part to replace averaging around 25-35 dollars if you can replace it yourself. If you do not know how and have to take it to a repair shop expect to pay 50-75 dollars in labor. The key is to listen closely when you insert the disk into the player, you should be able to hear it spin up. If you hear nothing then that is most likely the problem.



2. The cd tray could be out of alignment. This is another easy and cheap fix if you have the proper tools. This could happen if you drop or pull and push on the cd tray.

3. The small gears are plastic and often break, this will cause the players other parts not to move and function properly also. They are hard to get to, but inexpensive to replace from the manufacturer. A visual inspection is usually required to determine if the small teeth have been broken, which requires for the most part taking out the carriage assembly.



4. The small belt drives either break or come off. Again, this will cause the other mechanical parts not to function. They are a pain to put back on also. There are usually 2-3 of them inside your player. These are located in the drive assembly and will usually require removal of the optical reader assembly to be able to get to them.

5. The Optical reader has malfunctioned. This is the most expensive thing to replace, so you might as well buy another player unless you can find a great deal on one someplace. You can check to see if the laser is firing with a visual inspection (DO NOT LOOK DIRECTLY INTO THE LASER) put in a disc with the case off and you should see the glow of the laser hitting the disc.



6. The tray also has a drive motor which can fail and cause the cd tray not to open and it also has a track that it rides on. Check these two components if you are having problems with your cd tray. The picture below shows the drive assembly with the tray open.

My DVD has problem read disc DVD. When I put inside disc VCD everything is fine. I have region 0 on my dvd.


hi,
i have got the same complaint some days ago. your players spindle motor is faulty.
its winding have some problem. spindle motor is that one on which the dvd spins. when u insert the dvd it is not rotating at the required rpm. thats why it is not reading. the problem will not be with video cds . because it doesn't required a high rpm. replace the spindle motor. it will not cost a lot. its sure that ur problem will be solved.
if then also the problem remains,
your player's laser pick up unit have some problem with its DVD laser. there are two types of laser in dvd players. one for reading and playing audio cds, mp3 and video cds and the other for reading and playing dvds. in your player dvd laser have problem. dont think that these are two separate unit. the lasers are mounded in the same unit. if any of the laser get damaged you have to replace the whole unit.
if u need any more assistance feel free to contact me through fixya.
bellow is the image of laser pickup mechanism

Hello Keilabb,
I am sorry to hear you are having a problem with your dvd player, but hopefully the following advice will help you correct the problem. The following are some common reasons why dvd players fail to read a disc or give you some type of error code such as "bad disc", "no disc", "disc failure", etc.

1. The disc is scratched or dirty- If discs have scratches, pits, or are dirty (finger prints are the most common cause) then the laser that reads the data on the discs will be unable to properly read the data. This commonly happens with older discs, but can happen if you rent from a movie store. If you hold the disc up to the light and tilt it back and forth you will be able to see any defects. If this is happening to ALL your discs then it may be your Optical Lens. The following link to my tips and tricks will provide you with instructions on how to clean your discs and give you other suggestions to keep them in good working order.

2. The Optical Lens is dirty- If the optical lens over time will accumulate dust and dirty on them. This component is where the laser comes through to read the disc data. It will present with the same errors that I mentioned above and usually will happen with every disc you try either old or new. The following link will take you to my tips and tricks section and give you details on how to clean it manually and offer other suggestions to help keep your dvd player operating in good working order. The following example picture will give you an idea of what the optical lens looks like:

3. The Spindle Motor has malfunctioned- The spindle and motor are the components that spin the disc. The disc must spin in order for the laser to read the data on the disc. If you listen closely when you insert the disc and close the tray, you should be able to hear the disc spin up. If you do not hear anything, or you hear the disc start and stop over and over and sometimes a squealing type noise, then the spindle motor is most likely at fault. The following link to my tips and tricks will give you more details on the most common mechanical failures of dvd players with pictures so that you will be able to see what these and many other components look like. It also provides you with other information such as average part and labor cost. I never like to suggest people try and fix an in depth problem that do not feel comfortable or have experience working with electronics or sensitive devices, because it if done incorrectly can cause further damage to the device and personal injury.

4. The Laser assembly has malfunctioned- This is basically the laser and it's components. This failure is not as common as the others, but it does happen. If the laser is not firing properly it will not read the disc data. You will also find this in the link provided in number 3.

I believe the problem in your case is most likely either 1 or 2, so try those solutions first. I am sorry for the long post, but I like to provide as much information as possible so that everyone I try to help are fully informed of the possible causes and help them find a solution to their problem. I hope that helps solve the issue you are having and please let me know if you need further assistance and I will be more than happy to help in any way I can.

Remember to ensure your safety when working inside any electrical device due to shock hazards (even when electronic devices are unplugged, they can still deliver a shock because Capacitors hold an electrical charge for some time even when power has been removed). When dealing with lasers, never look directly into them because they can cause eye damage. I wish you all the best

If you would not mind, please rate my help. I would greatly appreciate it. Thank You

my DVD player won't play the DVD's so what is the problem, it just started not playing them


Hello,
Sorry to hear you are having some issues with your dvd player, but hopefully the following information can help you determine what the problem may be.
The most common problem that causes dvd players to not read the discs is because the optical lens is dirty and needs to be cleaned. The optical assembly uses a laser to read the data from discs and over a period of time dust and dirt build up on the lens which prevents the laser from reading the discs properly. The dvd player will usually give you some kind of error message such as "no disc", "cannot read disc" or some other message along those lines.
The easiest way to clean the optical lens is by purchasing a cd/dvd cleaning kit (you can purchase them at most stores that sell electronics such as Best Buy, Wal-Mart, Radio Shack, etc).
The next common problem is that the disc is dirty or scratched. If you hold the disc up to the light and tilt it back and forth you can see if the disc may have small scratches or has some form of dirt (such as finger prints). Again, you can purchase kits that will help you remove scratches and dirt.
Dvd players can also encounter mechanical problems that will prevent them from reading discs. The following could also cause the player to not read the disc.
1. The spindle motor: Discs spin inside the machines so that the optical assembly can read the data. If you listen closely when you put a disc in and close the tray, you should be able to hear the disc spinning up inside the player. If the disc is not spinning at all or it spins a little then quits and continues to do this a couple more times then the spindle motor is likely the problem and will need to be replaced. The part is not expensive (average cost $25-40 dollars), but the labor could cost you between $50-80 dollars if you pay a technician to replace it.
2. The optical assembly- This is where the components are contained that uses the laser to read discs (including the optical lens). If a component inside the optical assembly has malfunctioned, the player will not be able to read the discs. Fixing this can be expensive depending on the part and of course the labor.
The following link to my tips and tricks page, will provide you with more detailed information on the components I mentioned plus a few more malfunctions. It will also provide you with pictures so that you will be able to see the components.

If you have the technical skills or feel comfortable working on any of the items I have mentioned, it will save you a lot of money. Remember, when working on any electronic component that you should exercise great caution because of a SHOCK hazard (which can happen even it the device is unplugged because capacitors hold electrical charges for some time even when no power is supplied) and when working with anything that contains a LASER can also be harmful to the eyes.

I hope this will help you determine what the problem may be so that you can get it quickly resolved. Let us know if you need further assistance.

If you would not mind, please rate my help. I would greatly appreciate it. Thank You

I haven't tried this yet, but based on the description, it looks to be the spindle motor not functioning properly. Read below:
