Hello
To replace the optic lens, you have to open the device and take out its CD mechanism out. It is a very skilled job. You must hage all the tools to open the device and enough knoledge in electroncis to do this work. If you have experience in disassembling and reassembling this type of unit, you can do it by yourself. You cannot replace the optic lens only. It is unit, whic contains optic lens. The unit as a whole is known as Laser Pickup Unit. OK.

SOURCE: lanzar model SD43MU(( dvd/cd player wont work not funtions for that wont even appear?

I have a similar Lanzar unit. I had it in twice while it was under warentee for the same issue. I also had it in a couple more times for other issues. It cost me about $30 shipping both ways each time I returened it. About a month after the warentee expired, the DVD quit ejecting again.

Bottom line, I would look at purchasing a different uint or use an ipod instead of the CD.

This combo devices have two lenses, one to play CDs and one to play DVDs. It looks like the lens that plays DVDs is defective and will need to be replace.
Try using a lens cleaner. If the lens cleaner does not work, the lens is defective.
If your device is less then a year old, still under manufacturers warranty.
Let me know if you need further assistance.

My dvd player will not play any dvds or cds... It says disc error


Hello,

how long have you been using this player? The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load Cd's. The weak lens is also what's making it say disc error.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all Cd's with no problem at all.

Good luck.

My dvd player plays cds but wont play dvds says disc error or unknown disc


Hello,

how long have you been using this player? The problem should be from the lens (laser).

The lens is weak and that's why it cannot read/load DVD's. The weak lens is also what's making it says "disc error" or "Unknown disc". It can still play Cd's because, Cd's does not contain large files, unlike DVD's.

Get a lens cleaner and use it to clean the lens, but if the lens still does the same thing even after using the lens cleaner, then it means you would have to change the whole lens completely to a brand new one.

By so doing your player would play all DVD's with no problem at all.

My Sony DVD/VCR combo will play cds but not dvds. I took the top of the player off and I can see that the dvd spins but it won't play. It used to play everything very well but just stopped working...


Please clean laser lens with good quality cotton bud gently and check dvd disc playback, if still does not play, replace optical lens block.
Let me know model number of your Sony DVD-VCR combo to provide you optical laser block part number info.
Thanks.

No Disk issues on device players like DVDs are caused by the following problems

Dirty Play Heads (Optical lens)
Bad CDs or scratched CDs on the surface
Non Compatible CD formats such as DVDs that are designed for some geographical regions and play formats
Also low electrical current is a major problem too

Your issue could reside amongst any of these problems

Check your DVD compactible play formats if its compactible with the CD you want to play.

If its compactible, then I suggest you get a CD Cleaner to clean to clean to Lens.

Also check your current output and if low, get a voltage stabilizer

Check the surface of the CD if its scratched and get a replacement.

Plays cds but not dvds


If the lens is clean (clean with cotton swab and alcohol), then the optics are failing. DVDs require more power and accuracy to be read than CDs. The ability to read CDs but not DVDs is usually a good indication that the optics are starting to fail.
