Won't play any media types

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,

Hello
Check its Sled Motor. Sled motor is one which get spins the disc we insert into it. If it is faulty, discs won't spin, and the set won't read anu discs, and will show no-disc display. OK.

The clicking noise is the optical unit trying to read the disc. When its working normally the CD spin's and the system reads the table of content ( info: on the CD ) and the disc stops till you give the next command , e.g PLAY etc. Now when the laser beam is weak due to dust on the lens or age, the unit starts to hunt for the CD by popping the len up and down trying to focus the laser beam to get a strong reflection. This constant up and down movement is the clicking sound you are hearing.
Either unit has dust on the lens or is due for replacement ( if it has done more than 500 / 750 hours ).

Please try to put in an ordinary audio CD track and see if this is detected. If yes the optical is working, if not there is no laser scanning and the possibility of the head being faulty is high.
Certain cleaner disks may not work but the best is to cleaning manually the laser head eye with a cotton bud, very gently and without pressing of the lens eye.
If there is still no result then watch the CD if it spins or tries to spin. If the head unit moves up or down to focus or in and out of the drive, if so the board seems to work correctly and the possibility that the optical head unit is the suspected fault.

Now certain cleaner disks are not read and so will not be tracked. Hence the rejection but the best is for cleaning manually the laser head eye with a cotton bud very softly and without any pressing of the lens eye.

Have you tried a DVD+/-RW ?

The noises that you are hearing will be the spindle motor trying to spin the DVD as the lifting presentation tray for the read/write head has not located, if the media is not spinning this will never be able to read the lead in on any DVD as it has not presented the disc in the correct place.

If is is out of guarantee then I suggest that you check to see if the DVD is spinning by removing the top cover with the power OFF then eject the tray and try to load the media a small touch of the DVD in the clockwise motion should cause the media to start spinning, this is for diagnosis only if this is the case then the spindle motor will need changing

What you are hearing is the attempt to read the disk. The unti detects that a disc is present and attempts to read it by spinning it first at CD speeds then at DVD speeds. It will attempt this a number of times before giving up and reporting "no disc". If you can get at the optics, try cleaning the lens using a cotton swab and alcohol. Next try to read a CD. If you can read a music CD and not a DVD, it indicates that the optics are starting to fail and need to be replaced.

Try to clean optical lens of dvd player with soft and nice quality cotton bud / swab by opening top cover of player.
There might be chance of lens sled mechanism stuck so move lens left-right for 2-3 times.
If cleaning doesn't work, you need to replaced optical lens.

A read of the disc has failed for a list of possible reasons; dirty media, dirty optics, failed laser, alignment all come to mind. In short, it's time for a shop service...accordianman
