I believe that this model uses a DVD mechanism that looks just like the ones inside a computer tower. The whole unit must be removed from the main chassis and then the metal cover removed. Once that is done, the lens should be visible.

My sony DVD player says hello when cd inserted

It should not say "goodbye". So, by "hello", it is saying that it is "waking-up".

Cleaning The Lens of your DVD/CD/Blu ray Drives , Players and Writers

Sometimes it becomes necessary to clean the lens of your CD/DVD/BR player. The symptoms indicating it needs a good clean is that it won't play your discs or that playback is jerky.

There are two ways to do this
  1. Lens Cleaning Kit
  2. Manually Cleaning The Lens

#1 Lens cleaning Kit

Lens cleaning discs are very convenient and effective when used often. It is recommended you clean your lens with a cleaner once a month.

You can buy these kits at any department or electronics store and they cost about $5-$10.

The kit consist of a disc fitted with soft brushes and sometimes a cleaning solution. You just play the disc in the device for a few minuets and that's it.


#2 Manually Cleaning The Lens

The lens cleaning kits work okay , but sometimes it is not enough to get the lens clean. This is when you would clean the lens manually.

WARNING : Remember to disconnect the power supply before removing the outer case and do not touch any electrical component even after the power is disconnected.

You will need :
  1. Q-tip x2
  2. Isopropyl Alcohol , Lens Cleaner or Nail Varnish Remover.
  3. Philips and/or Flat Screwdriver
Not all DVD/CD/BR devices are opened the same way. Normally , with computer drives , the cover is fastened with 6-8 screws on the bottom of the drive.

With DVD/CD/BR players , the cover is normally fastened with multiple screws on the sides , back and under the unit.

With Portable players , it will not be necessary to remove the cover as the lens is visible without disassembly.

When the device is open and you can see the disc tray , you will need to open the tray in most cases to gain access to the lens.

ON PC DEVICE : Push a pin into the release hole on the front of the drive and move the tray out from the inside.

ON PLAYER DEVICE : Plug in the power , eject the tray with the remote and plug the unit out when the tray is extended.

Now you should see the DVD/CD/BR lens in the unit which looks like this :


Now , take a Q-tip and dip it slightly in your cleaning solution of choice. Very gently rub the q-tip in a circular motion over the lens being careful not to put pressure on the lens. Let the q-tip just rest on your fingers.

Now take the second Q-tip and pull at the cotton tip to loosen the fibers. Now also in circular motions , dry the lens gently. Make sure that none of the cotton strands stayed behind on the lens and then close up the drive.

And that is the instructions on how to clean your DVD/CD/BR drive's lens.

If you found this tip useful , remember to vote!
Kind Regards

Where is the lens to clean on Sharp component system?

To clean the lens, you have to open the device and access the loading mechanism. it is really a skilled job. If you want to clean the lens only, there is a simple way. Just put in a lens cleaning disc into the device, and play it for about three times at least. Take the disc ejected each time, and put it in after. The lens cleaning disc can be bought from most of the electronic spare part selling shops at your town, and won't cost more. You can clean the laser head lens, by this way, without opening the device. OK.

Poor webcam. very dark and grainy.

Usually this happens when the computer is "well-traveled" or an older model. It's likely that the lens is just dirty. Use a camera cleaning kit (usually less than $10 at Wal-mart) and clean the lens. If you don't have access to a camera cleaning kit, use 99% alcolol and a Q-tip. DON'T USE ISOPROPYL (RUBBING) ALCOHOL. Isopropyl alcohol is only 70% alcohol and will leave a residue on the lens that will be just as bad as the dirt.

Can not play disc

You can try a lens cleaning kit. If it is the kind that comes as a disc all it will do is lightly brush the lens which may not remove all the debris. If you disassemble the player you can easily get to the laser lens. It will usually be fairly accessible once you remove the DVD case. Sometimes it may be located within another box that needs to be disassembled before you can gain access to the laser. The laser unit will be located on a rail system and will have a small clear lens about the diameter of the eraser on a pencil. You can gently clean it with a cotton swab and lens cleaner or rubbing alcohol works just as well. Try that first before buying the lens cleaning kit or replacing the player.

Loading DVD

That means that lens are dirty.

Try first cleaning the lens with a DVD cleaner disk. If you can access the lens you can also blow some canned air on the lens.

If that does not work, then the unit must be disassembled by unscrewing the screws at the bottom and at the back to access the lens pickup and clean lens directly with cotton tips and isopropyl software.

Disk error

That means that the lens are dirty, and the unit cannot read any disk.

Try first cleaning the lens using a lens cleaner kit (the ones with liquid cleaninc solution), like the one here :
Allsop Ultra Pro Lens Cleaner for CD, DVD and Game Consoles

Ifthat does not work, then you will need to access the lens inside theunit by opening the cover and accessing the lens pickup, and gently clean lens by using isopropylalcohol and ultra soft soft cotton sticks.

Here is how the lens look like:

I put a dvd in and it always comes up as "No Disc", everything seems to be working and moving fine.

It looks like you have a dirty lens problem.

Start cleaning the lens with a dvd lens cleaner kit, possibly a good one with cleaning solution.

If that does not work, the you will need to take apart the dvd, access lens pickup, and clean lens manually with cotton and lens cleaning solution, or isopropyl alcohol.
