KENWOOD LVD-K9100 CD, CDV, LD, LASER KARAOKE PLAYER Original owner, in superb cosmetic condition, this unit was just professionally cleaned and serviced, all parts function correctly, except the laser is weak and will not read Karaoke LD’s. Do I need a new Laser, and if so where do i get it?

    When inserting a LD, the player ramps up and the Track number display shows”00”. When play is selected, nothing happens. When disk side “B” is selected the track display goes blank. Again nothing happens when play is selected. I have used several LD’s with the same results. The AV service Tech that just cleaned the unit said the laser is too weak to read the LD’s.

    When I press the play button, nothing happens, how would I get the unit to read the CD cleaner kits?
    Also I have searched for other Kenwood CD,CDV,LD players and found none. Did Kenwood make this product or is it a Pioneer? The unit has made in 1993.

  • R_Schemenaur Mar 14, 2008

    My AV tech, said the lens are clean, he also told me that because I?m a smoker, that he feels that smoke has gotten into the laser assembly. The only correction would be to replace the laser. He said he would charge me to open up the case and try to find a part number, he also thinks the laser might be from pioneer.

If the laser diode inside the optical pickup is dead or weak it will do exactly as you have described. It is a very common problem with cd and dvd players.

Things You’ll Need:

  • Lukwarm water
  • Soft, clean cloth
  • Karaoke machine cover
Maintain Your Karaoke Machine With Regular Cleaning Step 1:
Clean the exterior of your karaoke machine regularly. Use a soft clean cloth to wipe down the karaoke machine housing. You can use warm water to help clean the unit, but it should be applied to the cloth, not the machine casing.
Step 2:
Avoid using cleaning solvents to maintain the karaoke machine. These can tarnish the surface of the machine. Solvents can also affect how the machine functions if they get inside the housing or into the buttons.
Step 3:
Clean the CD laser lens occasionally. Use a CD lens cleaning disc for the best results. Place the disc into the karaoke machine and run it according to the enclosed instructions.
Step 4:
Try cleaning the CD laser lens manually. Open the CD player and locate the CD laser lens. Wipe it off gently with a clean cotton cloth. Do not use any solvents.
Properly Store Your Karaoke Machine Step 1:
Turn off the power to your karaoke machine after each use. This will help the machine from overheating.
Step 2:
Store your karaoke machine in a cool, dry place. Moist conditions can cause the machine's cabinet to warp and could cause rust on interior electrical components.
Step 3:
Keep your karaoke machine away from direct sunlight. Direct sunlight can warp plastic buttons and screens on your karaoke player.
Step 4:
Consider covering your karaoke machine while not in use. This will help prevent dust from accumulating inside the buttons.
Handle Your Karaoke CDs With Care Step 1:
Store your karaoke CDs in their original cases to reduce the risk of dirt accumulation. Dirty CDs can cause tracking problems when put in your karaoke player.
Step 2:
Keep your karaoke CDs away from direct sunlight. Even while in their cases, CDs can easily warp when exposed to direct sunlight. Warped CDs may get stuck inside the karaoke machine.
Step 3:
Pick up karaoke CDs only by the very edges of the disc. This will help keep the discs free of dirt and fingerprints.

Here are some generic things to try.

    Considering the age of the player, it may not pay to fix it.
    If the unit needs the laser, you may not even be able to get it.

Your problem is pretty straight forward..The lens is damaged or needs to be cleaned.. You can get a lens cleaner CD with liquid(costs about 5-10$) insert it in you player and press play. THen take it out put the liquid on the brushes and clean it once again.. Then check if it works.. If it doesn't work then you will have to replace the laser( Lens mechanism).. Let me know if it worked so that we can proceed further

Probably your best bet is eBay, you may be able to find a LVD-K9100 or K9200 that is not working but has a good laser.

Have you tried cleaning the lens with compressed air?

You could ask on alt.video.laserdisc on Google groups, you may get better results as they would be Laserdisc enthusiasts and may be able to help better.

It was seem that the Internet has forgotten about the LVD-K9100, the K9200 seems a little more popular, and they maybe use the same laser/lens???

    Here is a link to where you can purchase the service manual for the LVD-K9200: http://www.user-manuals.com/advanced_sea...



    Unfortunately there are no resources for the LVD-K9100 on the Internet.

    That makes sense, it would be easier to look at the laser for a part number as there is nothing on the Net. Unfortunately you don't have many other options. And it isn't a guarantee to find a replacement even once you have the part number.

Perform disk cleaning process. You can obtain disk clean up kit in most IT stores . Choose the one with liquid. inform the outcome after cleaning. So I can post possible next step solution.

My kenwood D R350 CD player keeps skipping on some but not all tracks. I have tried to CD cleaner but this didnt work, what can you advise


The problem is in the laser pickup assembly, overtime the laser becomes weaker until it can not track properly resulting in skipping and eventually not been able to read the disc. My next step would be to get a CD cleaning kit which you have already done. The only option is replace the assembly which is not cost effective, but far cheaper to buy a new CD player.

I have a Pioneer LCV-300 Laser Karaoke player; but without the "receiver" or "commander" unit. Is this unit necessary for the disc changer portion to operate or power on?


I may have a CD-V300 commander Auto changer if you can supply me with an owners manual for a LC-V300 laser changer. I also have an auto changer CD-V2000 if you can use it. If you can please contact me. Thanks.

I have a kenwood MIDI M-45 /MIDI M-757 audio system. The CD player won't play. The disc loads but error comes up NO DISC, can you help????


The cd unit is not reading the disc, the laser pickup may be dirty, or the pladder motor that cd sits on may be defective. If you can get at the laser pickup lens, clean it with rubbing alcohol with a Q-Tip very carefully in circular motion and allow several minutes to dry.

CD player says no disc...cleaned using lens cleaning disc and and worked normally but now saying no disc again...recleaned and working normally again but if I skip a track it doesn't seem to find the next...


You need a new laser. Even if a technician turns up the laser power level and it works it won't last more than a few months or so. Time for a new laser or most likely a new unit because that is almost always more cost effective. Good Luck!!

Dr Dray would like further assistance robotek!


no worries mate... firstly, remeber that mains voltages can kill and you should always disconnect the unit from the power before taking the covers of and work safe.
What we plan to do is to
  1. Clean dried grease from the worm drive gear that move the laser optics back and forth.
  2. Clean the laser lens
  3. lube the spindle motor bearings
You will need

cotton buds
methylated spirits
light oil
fine sewing needle

Using a cotton bud moistened with metho, clean the the old dried grease of the worm drive gear. Removing the laser transport from the unit is often the best way to do this. Be sure to not touch any of the connections to the laser itself if you unplug it from the main board. They are very electrostatic sensitive, and can be damaged by the static charge on your person. Be meticulous to clean it well. I use light oil(sewing machine) or if you have it, some graphite grease to then relube it. Apply a drop of oil to the top bearing of the spindle motor (use a fine needle with the oil in the eye to get under the platter to do this. Clean the laser lens with a moistened cotton bud and then polish with a dry one to be sure there is no residue.

Reassemble the unit and see how it goes. If you have any more dramas, a replacement laser assembly can be got and basically plugged into these units with no extra setup. I reccomend using a marantz original if you can . It is described as a cdm12.1 transport. Let me know how you go.
