Hi Leostg,


Turn them both all the way to the lowest setting.  You then have to watch the position of the little hole on the cogs. They have to move in opposite directions.  Move them 4 clicks each in the raise drive direction. Test the Discs.  CD, PS1, DVD, PS2 silver, and PS2 Blue.  Keep raising the cogs equally 4 clicks, and testing until you get all the discs reading. You should be sure that everything is working on your Laser and dsic reading before you do this though.  Use a Magnifying glass and Flashlight to look at your Laser lens real close to see if you have any film or smudges.

Please do not vote until this is repaired, you only have one vote so please dont cheat me out of a solved vote. I have given you a good tip.

Hi, I have a NSM ULTIMATE that all of a sudden is giving me the error message 'No disc found' even though the disc is spinning. Any ideas?

Sounds like the laser pickup unit has damaged. Replacing this part to Blu-ray players is a very skilled work. It will be best to contact any experienced service technician to replace and to align it.

Hi, my Philips DVP5100 keeps ejecting DVDs. When loading a disc, it reads it for a short time showing LOAD. Then it ejects disc. Does it mean laser is gone?

It sounds like the drawer assembly may be out of alignment...may be caused by shoving the door in instead of pressing the button to load the dvd....the timing of the drawer and the laser assembly is critical to the proper operation on most dvd's...another possibility is that if the unit has a belt drive for the door load components, the belt may be slipping enough to cause it to not fully load...It makes the player think that you never put a disk in it so it will keep ejecting because it never received a "full load" signal from the drawer components. You can take the cover off and watch the operation of this to see if it is loading all the way..if not then you will either need to have repaired or try to obtain the service literature yourself to re-align the gears to make it load properly

CDP CX355 Seems to Skip- sound similar to what happens with LP record when dirty.

If the player "skips" after 15+ seconds the likely problem is the split rack&pinion used to position the laser. The split rack is sprung to remove play or backlash when meshing with the driver cog. This split rack can jump cogs over time, eventually becoming ineffective. The solution is to remove the laser assembly and gently disengage the driver cog, compress the split rack and re-engage the driver cog. This should solve the skipping problem.

Disc not reading

If you're getting a Disc Read Error (DRE), it could be one or both of these things.

Your laser lens is dirty or broken and needs to be cleaned or replaced, or your disc tray is faulty and needs to be serviced.

Try cleaning the lens and see if it will read. If you can hear the disc spin in the PS3, then your disc tray is fine.

Sony PS2 format disc

If it's the latter, make sure that the disc you are entering is in fact a PS2 format disc and that it's seated correctly. If that doesn't work, try using a different disc, and take that disc to a different PS2 to make sure that it's not defective. If the discs are fine, but the PS2 still does it, it could be a permutation of the famous DRE syndrome.the most sure-fire way is to order a new laser and install it yourself. (That is unless you are under warranty. If you are under warranty, get it to Sony right away.)

PS3 wont play disc's

If you have problem with loading your disk or some kind of media a most common error is Disk Read Error,or in a short way DRE.
Ps3 Laser is a very precise mechanism and optic and also a well none proble for the all machine right now on the Market.
Sony had the same problem before with PS2 and tried to fix the same issue all ready but without any luck at all.Actually i do believe is Part of the Market Strategy making the laser not to strong so people can buy new laser and keep the techical support alive.Most common error on Ps3 is DRE and some other like power supply Failure or Hd defective.
What is sad actually the fact the laser is Collapsing onthe spot.
On the ps2 you have some time to realize the laser is bad since the machine start not reading well or freezing during the game.On ps3 the laser stop working and that`s it.
I suggest to replace laser or try to clean first because sometimes if you are lucky the laser start working again

How do you align a laser in a dvd player?

Hi there jhill255,

Normally the lasers align themselves off of the disc place in them. If there is something where the laser is "out of whack" and not tracking regrettably most DVD Players don't have a tracking feature (again because its mostly automatic).

One option you might want to try is a DVD lens cleaner. Some claim to be able to re-align the lasers but they will at least dust off the lens and clean it up.

I hope this helps.
Go Ahead. Use Us.

Dvd's not playing

This might be a problem with the alignment of the actual laser in your device. You mentioned that you cleaned the player? Question, how? The reason I ask is because if you used alcohol and canned air you many have left a residue on the laser facet which would cause such a problem. I would suggest that you use an apporved fiber optic cleaning solution and attempt to clean the laser, (it is best to let a pro do this). Then check the laser alignment and power with a laser power meter.
