You can purchase a DVD cleaner disc (assuming your Blu-Ray player model supports DVD playback), follow the pack directions, should shift the surface dust off the laser lens within minutes. You do not need to remove covers or go to a workshop for this one if it is just a bit of dust.

Cleaning the lens via this method is probably the cheapest, safest, and simplest option. Do this first. If cleaning it doesn't help, then the next step would be to consider taking the unit to a service centre and have them look at it, get a second opinion and a quote (while you're there) for them to clean it professionally and check alignment.

Up to you - and I also recommend that you lightly (and gently) clean the disc tray (with a soft dry lint-free cloth) as well to prevent further dust shifting from it to the discs then onto the lens in future. Make sure all the discs you use after that are clean before playing; this also helps.

CAN THE panasonic dmp bd35 PLAY 3D BLU-RAY DISKS

I understand the DMP BD35 is a normal blue ray disk player and not a 3D. Please see this manual if you want to be doubly sure.

However something like a DMP BDT360 will play 3D blue ray discs and you can view it on a 3D ready TV.

The DVD keep spinning but won't play

see the next steps and fix it. God bless you
Clean a DVD disc:
  1. Hold the disc by its central hub and outside edge.
  2. Blow dust from the bottom surface with a can of compressed air.
  3. Clean dirt and fingerprints from the bottom surface with a lint-free cloth dampened with CD/DVD-cleaning fluid or denatured alcohol, wiping from the center outward.
  4. Clean the objective lens:
  5. Remove the housing and lift the hold-down clamp to expose the lens.
  6. Remove dust with canned air or soft brush. If needed, use a foam swab or a camera-lens tissue dampened with lens fluid.

PS3 won't accept certain disks. A few disks i have won't play in my ps3. it happens to both blu-ray movies and games, and it seems to only happen with blu ray disks. i'll put the disk in, and...

The noise is actually a product of dust from a blue ray disc.Over time these discs heat up and leave a residue on the blue ray lens.
Try using a lens cleaner to remove dirt and clean lens.
Also i read an article that using a wireless controler can also cause freezing of the blue ray.

My 3D blu ray does not not play on my LGBX580

Hi you may need to update the firmware of the DVD player. If that don't work it may be the DVD player itself.

My Sony DAV-DZ720 Theater System not read the some dvd disc,.,i think problem is in lens system, me to fix lens pls,tanx

First try playing a CD. If that too skips you can clean the lens by opening it.Dust on the lens will effect all types of disc and will not be selective.
You can buy a lens cleaning disk from any Cd store and play it to clean.
The cleaning action takes place only if the disc rotates, so keep the top lid off to see if it rotates.
If you have crossed 500 hours of playing may be the lens is due for a change.

How do I clean my blu ray player?

Hi, Music and game discs collect dust and dirt on their surfaces overtime. This build-up can interfere with the sound and performance of both discs and the player system. Cleaning fluids and cloths will aid in keeping a Blu-ray discs clean, but to clean the lens of the player, some dissembling is required. Below are instructions on how to open up a Blu-ray player and clean the lens on the inside.


Things You'll Need:

* Blu-ray player
* Screwdriver
* Lens cleaner
* Cotton swab

Turn Blu-ray player over and remove the edge screws holding the bottom plate onto the drive using a small Philip's head screwdriver. These screws are located opposite each other on the bottom edge and one has a metal piece attached. Remember to reattach the metal piece when replacing screws later.

Remove the bottom two edge screws located near the center of the base and the three screws holding the base plate at the opposite edge from the screws in step 1. Again, one of the edge screws will have a metal piece that goes back in place later.

Extract the motherboard connectors. Once the screws are out, simply lift the lid and pull out the connector. The cable remains connected to the motherboard.

Remove the motherboard by lifting it and turning it to the right to pull out the cable connection. Do not yank the cable out. Grip the end plug firmly to release the cable.

Turn the player back over the right way and remove top cover to unscrew the four sides and one top screw holding the lens cover in place. The lens cover moves to the right so lens is accessible for cleaning.

Use cotton swab dipped in a little lens cleaner and clean the lens using a circular motion. Dry the lens using same motion with other end of the cotton swab.

Reassemble machine by reversing these steps.

Thanks for using fixya........

I have Acer 6930G. DVD drive will play CDs but says no disc when I insert DVD Blu ray or normal. Help!

POSSIBLE solution... (don't shoot the messenger on this one, lol!)

I'm sure you have tried, but have you cleaned your optics lately? The best thing about Blu-ray is that it uses a much narrower laser beam to read the data, so more "stuff" can fit on a disk... however, this leaves far less room for error. It may be able to read a DVD, since the DVD's "grooves" are much wider, and a CD's "grooves" are like the grand canyon compared to Blu-ray...

Using a Q-tip and a small amount of rubbing alcohol, and GENTLY rotate the swab across the lens, rotating it in the opposite direction you are wiping. This should "lift" any dust or grime from the lens. I would also clean the tray with a soft lint-free cloth (using an air-can just moves the dirt around, doesn't solve the problem)

Hope this helps!
