Question about DVD & Blu-Ray Players

2 Answers

TV screen reads "this type of disc cannot be played. Please insert a different disc" However, the disc will play on another player. Other discs will play on this player (PV-D4734S), but some new ram discs will not play. Is there some programmable change that I need to do?

The laser lens is probably dirty and needs to be cleaned, please follow the directions below.

1. Purchase or borrow a lens cleaner disc and try it first. You can find these things really cheap at any large department store. They usually get the job done well. However, you may need to clean the lens manually if the store-bought cleaner fails.

2. Remove the outer casing of the DVD player. Remove the screws that mount the top casing onto the bottom of the DVD player and slide the top casing off. This will expose the DVD deck, which houses the laser pickup lens.

3. Find the lens. The lens will be glass and under the DVD clamp. The lens will probably have a blue tint to it. If you are having trouble finding the lens, you could shine a light on the components and watch for the reflection.

4. Use a cotton swab and some isopropyl alcohol to gently wipe the lens. Just a quick scrub will do. Dry the laser pickup lens with the other end of the swab.

5. Give the lens a few seconds to dry and replace the covering of the DVD player. Test the efficiency of the player. If necessary, repeat the process.


Let me know if this doesn't work and we can try other options to get it working.


Thank you for using Fixya and Good luck.

Technika combi unit dvd player wont read discs anymore


Hello,

how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it cannot read data/files on DVD discs.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Regards.

Hello
Either your DVD players Laser Pickup Unit is dirty or defective or its 'sled' motor has damaged. Sled motor is one, which spins the disc inside. if it does not spins, the main system IC won't get any signal that the disc is "IN", and will show the messege "No Disc". The same will happen if the laser pickup unit is defective or dirty. Insert a Head Cleaning Disc into the system, and play it for atleast 3 times. If there is any dirt or dust, this will solve your DVD's problem. If not, it should be serviced by any skilled technician. It is not a user reparable item, as you have to take out its loading mechanism completly out of it for repair. OK.
