Are the disks copys? are they badly scratched? if not you could try unplugging the player. take it apart and locate the lasor lens usually under a plastic plate held by two small screws? get a cotton bud and dip one end into isopropyl alchohol or meths and clean the lasor lens rubbing lightly in a circular motion then with the dry end of the bud wipe lightly the lens dry, put the set together and try a disk, if the above does not work a new lasor is needed,

SOURCE: It won't read disc. After loading, it reads No Disc

Sounds like a read error fault , possibly a laser malfunction sometimes dirt on the lens will cause this try a good CD cleaner if this is no good I suggest a free engineers estimate at least you can then ask again on here how to fix it . My honnest guess is either a duff laser or software corruption . I have known seating of the tray to cause this also not returning fully back into machine , usually caused by children and alien matter ? shall we say such as choclate or M&MS kids shove stuff everywhere ? bless them lol
hope this helps Regards Vortash

SOURCE: when i insert a disc in my dvd player it reads "no

Hi mgarragh1,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust the lens can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Replace the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.


Ifyou already cleaned the lens, and confirmed that the ribbon is good as well as the motor then I would advice you to send it to repair shop because the next step should be done with an expert because it is quite technical diagnosing the fault between the pick-up lens and the main board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hi,
It seems that optical laser block gets fail to read data on disc and possible cause could be dirty/ clogged lens or optical laser block failure.
Put lens cleaning disc in unit to clean optical lens and check DVD playback, if that does not solve the issue then optical laser block would be defective and requires replacement that would cost approx new player price.
Hope these info will help.
Thanks.

HOW DO I TYPE NAMES OF CD OR DVD ?


You can't add a title to a disc from a player (such as this). You can only add a title on a disc writer before finishing the disc. (The only exception is RW (rewritable) disc which can be unfinished.) If a title (disc, chapter or track) is on the disc you can display it. Press Title on the remote. If you want to read all of the information on any disc, insert the disc and press Load on the player (when in Stop mode) or press the TV/DiscExplorer/DVD button to set the unit in Disc Explorer mode. It takes about 30 seconds to load the data. Press Stop to cancel the data search. Then use the folder buttons (ALL,DVD,CD,A,B,C,D) on the remote or the player to read the various items. Press Return to leave the folders. If you enter the Disc Explorer while playing a disc, the playback will stop and you will have to press Play to restart (Resume is not an available option).

Once loaded the player will store the data even after you remove the disc. It will clear when a new disc is inserted or you press Load.

The manual for this unit is available at: http://esupport.sony.com/US/perl/model-documents.pl?mdl=DVPCX850D .

I hope this helps.

DVD player cannot read DVD disc.


Have you tried other DVD's in this unit and they work? If so it might be just an incompatibility issue with that DVD in your TV.

Player Does not play any type of Disc


Press case lid where it attaches to player. If this makes unit react you have a defective lid switch. You can probably put some weight over it to hold lid down and it will operate. Otherwise switch must be repaired
