DVD SOHD-16P9S drive doesn't read any kind of CD or DVD


hi,there is no problem in drivers .
check the hardware parts
there are 2 possibilities in your case
1.the laser beam which reads the dvd or cds is malfunctioning
2.ensure that the cable & buses are properly connected

..
in case laser beam is damaged you got to get it repaired for proper functioning



all the best

WHen A CDROM Begins To Fail... It will Produce Symptoms Such As What You're Experiencing..
Typically This Happens With Multi Drives....
Multi Drives Are All In One Drives.... DVDrw/CDrw

And WHen They Begin To Fail.... THey Will Only Read Certain Brand CD/DVDs... (typically The Generic Ones Aren't readable/writable)

Or When Some Begin To Fail... THey'll Only Read CDs and not DVDs, or Visa Versa...

try to load this software, this should allow you to play DVD in windows media player

Try to check the regional settings of your dvdrw and and make it is set to your region.

Try This:

1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-
BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer
8) Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone

Hi - I would suggest that buy a cleaner for the drive, and try playing you cd's afterwords. If it still playing up then copy some music from the computer onto a brand new cd and play back. If that still has the same fault then you may need to but a new drive.

I hope that helps you.

Please let me know how you get on.

Regards,

Philip

Hi,
Sorry I can't offer any help, but then again, even Liteon couldn't help and posted a notice on their website a while back stating that these units were subject to drive failure.

" DVD-RW Drive SOSW-852S
NOTE: This is a system integrator product. Due to compatibility concerns, which may cause drive failure, we are not able to provide any firmware upgrade for this product. For technical support, kindly contact your vendor."

My recommendation is to get the exact replacement that Acer recommend. OR a third party equivalent.

In saying that as long as one has a warranty for said device, then really anything else is a moot point.

I think you will find that the Panasonic drive will be more than suitable.

replace the drive but stay away from Slimtype and sony
