White screen not reading disc including CDs, DVDs. It appears that the lens/motor is not running. plain white screen is displayed. what could be the problem.

take it to a shop that installs remote starters dvd players etc... have them make sure the connections to the radio are right also try the neg cable wire make sure there is no corrosion on it

Hey,

have you tried a lens cleaner? the lens may have gone bad and would need to be replaced. Do you have warranty on the player?

Have a detailed answer on wiki.answers under how to fix a dvd player. My conclusion is : 1. If the cd or dvd player won't start a disc (might display 'no disc') open the box and get good access to the laser lens (quite easy in many models). Clean the lens with an ear-bud (q-tip) and add some alcohol (I used after shave) on to aid the clean if there are still reading problems. Persevere with cleaning before trying option 2.
2. If it's selectively rejecting certain dvd's (and the problem might have become worse with time) consider ever-so-slightly bending the fine wires that suspend the lens over the laser, in an upward direction. Be very careful and read all the observations above first (on Wiki).

means it has a problem in the reader or lens...

well, the 40gig model of the ps3 can have either the dual laser lens, or the single laser lens in it. they started out with the KES-400A single laser lens, but somwhere along the line, they started putting the KES-410A dual laser lens in them, which is supposed to be a more reliable laser lens, but they do fail as well. the most common reason why a ps3 won't read ps3 games and bluray discs, but will read dvds or cds is because they have a red diode that only reads dvds and cds, and a blue diode that reads bluray and ps3 game discs. i would say your blue diode has kicked the bucket and needs to be replaced. you will either need to send the system to sony for repair, or to a third part company to have it replaced, or you can replace the laser lens assembly yourself

This problem is normal and exists with many CD/DVD drives.
On some of the drives, if you put in blank discs and try to open the disc in My Computer or Windows Explorer, Windows displays no contents or a blank disc. Whereas on other drives, you get the error message that you mentioned about incorrect function.

What software are you using to burn CDs or DVDs? Are you able to burn CDs but not DVDs or you can't burn both the discs? Did you try a CDs with a different make/manufacturer? Some drives refuse on some disc makes. Try another disc and another writing speed, or try the lowest writing speed available with your software.

Hope that helps,

what do you mean not recognized? not detecting the drive or not reading? if not recognized by windows you can check the driver for drives in the windows if not reading it is the lens problem..if the lens problem, the solution only is to replace the lens or to replace the whole drive

Reset you player by doing the following:
With the player on, hooked properly to your television, and on the correct station:
Open the tray
Close the tray (with no DVD inserted)
Hold the stop button down for a full 5 seconds
The CyberHome screen should appear. You should be able to play your dvd's now.

s it possible that moisture got underneath the lens? NO
try a music cd,
sounds like the lase maybe getting weak.

upgrade the firmware on the product.
