Why Does My DVD Player Say 'No Disc'?

A TechLore "Ask the Experts" Question...

Question:

I have a Sony DVD player model DVP-S560D. When I insert the dvd into the player I get a message on the player telling me to insert the disk.

Why isn't the player recognizing the disk already in the player? Does something need to be cleaned?

Thanks for any help.

Answer:

I'm going to assume that you're having this problem with all DVDs and CDs that you insert into the drive. If this problem only occurs on one disc, the problem is usually with the disc itself.

There are many reasons why a DVD player may be incapable of recognizing a DVD when inserted.
  1. Many DVD players are not able to properly detect and playback recordable DVDs. If trying to play a DVD disc that is a DVD-R/RW or DVD+R/RW, you'll need to refer to the DVD players documentation on compatible formats.


  2. Insert the disc and listen closely by placing your ear to close to the drawer of the DVD player. After the disc tray has closed, you should be able to hear the disc spinning. If you hear no such sound, it is common that the disc is not spinning up, which is why you would recieve a "No Disc" message when a disc has been inserted. In some cases, it can be difficult to hear the disc spinning, so you could remove the lid of the player to actually see if the disc spins.


  3. If this is the case, you could try to determine the cause of this, which is usually the "hat" above the center of the disc is stuck and needs to be repositioned to lay against the top surface of the DVD. If you are uncomfortable doing this, you'll want to bring the DVD player to a service center.

  4. In your case, the DVP-S560D is an older DVD player, and I'm sure it has had its fair share of use. Over time, dust and deposits can accumulate on the laser that reads the disc. In many cases, DVD players with this problem can still read CDs. You could try a DVD laser cleaner, which is usually a disc that has a tiny brush glued onto it. Run the cleaning disc 2 or 3 times, and try it again. Try both CDs and DVDs, since CDs are easier to read than a DVD.


  5. After a DVD player has been used for awhile, another common problem is that the laser in the DVD player becomes misaligned, inhibiting its ability to read DVDs. In many cases, DVD players with this problem will still be able to read a CD. I'd try a cleaning disc first, since the only way to fix this problem is to bring the unit to a service center for repair.


  6. There are other possibilities for the players failure, such as a defective laser motor (the motor that moves the laser), bad spindle motor (the motor that spins the disc), as will as other various circuit falures that could be the cause.
Try all things you can do yourself to repair the unit. If none of them are successful, you will need to have the unit repaired, or purchase a new DVD player. As a general rule-of-thumb, if the unit repair cost exceeds 2/3 the cost of a new comparable unit (in both features and quality), then don't bother fixing it. You'd be better off with a new player.

Let us know how it goes by following up in the discussion page below.

i am has replace with new one my optic & motor but my dvd player still send message error

November 12, 2008 2:43 PM

if you replaced the laser mechanism ( with the comunication board ) and the motor then it is most likely the processing board and thier usually not cheap and sometimes not available , and after some time will not be made or sold ,also always check to see if parts for your device are available or if they have been having problems getting the parts before spending money at the repair shop on a device that will not be able to be fixed

it may not be able to read that type of formated dvd
check your player for the compatible formats

March 14, 2009 9:08 PM

you got very good comments switch to a more updated player with the format to mp3,wma,and varies format

I had a dvd lens replaced coz it used to spin very well but could read any disc! Help me

July 14, 2009 4:13 PM

I have an iview-102dv. As you said above in #2, mine is a 'hat' no contact problem. It is a hand me down from a friend. He said the shelf above dropped on the player, and after a while it stopped playing completely. I openned the thingie and found the bottom spinning but it did not make contact with 'the hat'. I tried to push down the hat, still it did not work. So I tried raising the bottom up with a flat screw driver and it made contact and it spun. Since the there was no dvd in there as I could not put a dvd and use screwdriver at the same time. I noticed that when I open the tray, the bottom thing goes down, and comes up when closed with the msg 'loading', so my dilemna is I cannot put a piece of wood or something to raise the bottom tray height as it would want to go down upon opening. Please help.

if it will not stay up , you need to determine if it is because of the tray not pushing on the plastic pin which in turn lifts the laser mechanism up to the cd/dvd
if helping the door close ( by pushing in on it ) makes it read the disc , then you may just need to replace the belt , otherwise it may also be wore down where the plastic lifts up on the laser mechanism

July 17, 2009 1:54 PM

Thank you repairdude. The player was bought only a month ago by my friend (who does not know how to set alarm on his clock radio, and I am no techie myself either). Nothing is worn or anything. Only the shelf above dropped on it once per my friend and it still worked for a few days and then stopped working with 'no disc' msg. Like I said the lower tray comes up, raises up when door is closed but for some reason does not make a complete contact with the top 'hat'. They seem to be in contact but perhaps not. Pushing the 'hat' down while 'loading' does not help but force-raising the bottow a wee bit does the magic. If anyone comes up with a solution please let me know, I thank you all in advance.

July 17, 2009 2:31 PM

if the plastic that lifts the "laser mechanisn" is not worn ,and the belt is not slipping, then the focus on the laser is failing and the lens can't stay lifted that high anymore or the lens is blurry and makes it hard for the laser to see , try cleaning the lens manually, otherwise you have a focus problem

July 18, 2009 5:07 PM

I know you're trying to help repairdude but maybe it's me who is not explaining things properly, not a techie remember. Okay, (1)insert dvd, no disc (2)unscrew the top and watch inside, close the door (top still open please remember) and watching, loading message comes up but the 'hat' is not moving and you can hear the 2 to 3 spinning going on underneath (4) unscrew the 'hat' and close the door (top still open), what do I see?- the bottom tray has risen up and is doing the 2 to 3 spinning and stops w/no disc (5) I screw back the hat and try it again with/(A) after closing the door (no dvd inside, please remember) and when it says loading, I press the 'hat' gently to make contact with the bottom that is going to spin, no contact, I hear spinning underneath which is the bottom tray doing it and with/(B) I repeated the exercise again but instead of pushing down on the 'hat' (no dvd inside, please remember) I raise the bottom tray a wee bit and I notice the 'hat' makes contact and the hat spins along with the bottom tray. Since there is no dvd inserted, I can never find out if there is other problem beside no spin. If I insert dvd with the cover unsrewed, there is no way I could raise the bottom tray, if I could I would be able to see when the dvd is being spun by the bottom and the top and whether it plays or I get 'no disc' again, then I would worry about lens cleaning, right. If I dont hear from you repairdude, thank you for trying to help me.

ok the belt is probably slipping that pulls in the tray and lifts up on the bottom tray( laser mechanism and motor assembly ) , you should be able to see this belt from the motor pully to a larger pully(gear pully) under the top tray in front , cleaning the belt or getting some liquid belt renewer(coating) , should fix that problem of the bottom not being able to lift up to the hat , unless the belt is to stretched out
also the hat can be popped out of the top cover and placed on a dvd in there ( because the hat should have a little magnet in the center and attach its self to the metal in the center of the cd/dvd spindle , holding the cd/dvd down and secure. hope this helps

July 21, 2009 8:49 PM

This one sounds more like it! Let me go home and see if I can follow your advice. Thank you Repairdude, I'll keep you posted. BTW I have to come to pub library to access the internet that's why the delay in checking your posts. Bye for now.

July 21, 2009 9:16 PM

no prob. I'll get a message when you post a message here , so no problem .

July 28, 2009 5:15 PM

I noticed the magnet deal, so it locks into each other. Earlier I had thought otherwise. I checked the belt. It was fine. I pulled the tray out completely and unplugged and found the lower part stayed lowered. I 'discovered' the latch in the front sliding which raised and lowered the spindle and all. I checked if that was out of groove. I unscrewed the four screws that and tied the spindle set and laser mechanism and everything to the floor and turned it around and checked. No deal. Not being someone in the know I will never be able to figure it out or fix it. To me it seems like the whole thing i.e spindle and hat when connected if raised a wee bit, like an eighth of and inch or so does the trick. I am giving up for now. Thank you for all the help. I know it must be something very simple for you guys but alas for me...! Thank you once again repairdude! Maybe I'll check here someday if you have to say something else. Same with my email, I must come to the library to check it. Bye for now and good luck with your life.

July 28, 2009 8:13 PM

ok, then the plastic pin that is guided by the grooves underneath the cd tray that lifts the laser and motor might not get guided good because of friction(needs some grease) or the plastic pin that lifts the laser and motor has friction and needs grease. but look for any wear on the pins and guides for the cd tray and the laser/motor assembly. hope that helps

August 3, 2009 7:45 PM

I could not locate "the plastic pin that lifts the laser and motor...", where do I look for it? I looked underneath but did not see any plastic pin grounded on the floor. The other pin "that is guided by the grooves underneath the cd tray" I noticed. It look blunt not pointed as if it is broken or is it snub-nosed to begin with. It had a little bit of freeplay on it, other than that I noticed on either extreme when I slide the latch it goes up and down ie to say the latch goes to the end on either side and it seems the tray is up completely, or down completely. Since the hat and the spindle do make a contact, it seems to me the whole thing needs to be completely 189* and it falls short a few degrees, right? So let me know about the pin and any other advice you might have. Thanks repairdude!

August 5, 2009 2:33 AM

hope this helps , it may just need some grease in there where the pin slides back and forth for the motor and laser( in between the crack that is just in front of the top slider pin and motor )( you will need a flashlight to see in there)
Photobucket

inspect the cd tray guides for any dammage and you will need to grease the pin and guide for the motor / laser. dissasembly of it will be required to inspect the pin and guide for the motor and laser . again hope this helps , let me know how that works

August 10, 2009 11:00 PM

I had the same problem with a 3 disc player. I took off the top cover and watched what was happening with the discs. The discs were not being picked up in the center and would not spin. The disc tray was off a notch or two. Possibly from being nudged too hard. I removed the center screw and centered the tray and screwed it back in. Now it gets picked up in the center and works perfect now. Hope it works for you too.

August 11, 2009 5:32 PM

Hi guys! Sorry repairdude I did not respond sooner. The bottom pin could not be found. I found one that was sideways with a spring surrounding it. Looked ok. Here is where I am at: I tried to raise the thingie (that gets raised anyways)by forcing it, it has a metal part, against the plastic that is part of the area that has the latch that I mentioned earlier sliding which makes the tray go up and down. So once it was jammed thus, I tried putting the hat on top of it, it spun!!!.. but alas with a cd inserted it would not spin as if the laser had hard time reading the disc. The disc would make just a half-hearted attempt at moving. So I surmised perhaps the laser is too close to the cd. In the meantime the hat came apart, the plastic part and the part that has magnet in it. So when I tried with plastic part alone, I noticed it spun fast the way it must which I had failed to notice earlier. So I have decided rightly or wrongly that the problem could all along be the hat which I noticed was out of sinc. Perhaps the hat always had the contact with the spindle and not spinning perhaps was due to the hat being defective, could I be right? So I have nudged back the tray down that I had jammed and am looking for a replacement hat. Radio Shack does not carry any dvd parts, so said the clerk there. Another thing I found out from my friend who originally gave me the player is that it never worked after it got banged when the upper shelf on his tv stand came down (the shelf has only three hooks, two on one side and one only on the other side). So it got banged. Something must have gone unaligned. The player was bought in late May or early June this year. The reason I did not respond to you earlier as I am in the middle of it all. I dont know how long it will take, that is why I am responding now instead of waiting for a long long time. Wish me luck.

August 11, 2009 8:44 PM

Thanks jchart. I'll look into it. See if I could center the tray in anyway. Thanks again.

August 13, 2009 8:43 PM

since it got hit on top of it , it may have made the spindle get pressed down more on the motor shaft,or , which also could have cracked the plastic frame and or bent the motor shaft. also check the laser lens carefully whith a flashlight to see if it has a scratch.( then clean the lens with a Q-tip to make sure its not seeing blurred vision , and then test it), as for the hat , can you glue the magnet back on? because that magnet holds the cd to the motor spindle so it can spin at a certain speed. also without looking directly into the laser ,check that it comes on and does a focus check on a cd
let me know if you detect any of these problems or if you need to dissasemble it more to check the mechanicals that raise and lower the laser/motor .

August 13, 2009 9:20 PM

Thank you. The laser comes on everytime, does its two flickers, ie, comes in flickers, spindle spins w/no cd in, and laser does its flickering again, and then I get the msg of 'no disc'. I have cleaned the top with q-tip once or twice. Tonite I am going to look for a crack. Also look for the other stuff that you mentioned. About gluing back the hat, like I said, the hat seems to me to be defective, always must have been, but I just noticed it. See the top portion that refuses to spin but spinned when raised, is I think because the top is not completely flat in its circumsference, that's why it would not spin, but spinned when it was raised that is when the top was not touching any physical part and that too not so fast a spin. So that leaves me w/looking for a replacement hat. I'll keep you posted. Thanks again repairdude.

August 17, 2009 9:34 PM

Oops, what I meant was the top of the hat (the one with magnet) was slightly lopsided, the reason being the bottom plastic which has three plastic stumps that was supposed to be fit into the openings in the metal part and be secured. On of the plastic stump was not properly fit into its slant in the metal opening, I had always noticed it but maybe not quite. I should have done something then. Now I am afraid I will have to tread it through the hat's cover, plastic in the bottom and metal on the top. I may not be able to make them completely perpendicular, both discs should be equedistance from each other. I am going to try it one of these days. Thouhgt I should let you know.
