Re: No Disc

Kimi's solution would be valid for me if the disc would spin, but it is not spinning.

Re: No Disc

If you sure that the system supports the disc's format.. and it wont play other discs... try to clean the CD lens. CD lens cleaning discs: Every CD, stereo equipment, department, discount, store - and even sidewalk venders - carries CD lens cleaning discs. Are they of any value? Can they cause damage? I generally don't consider CD lens cleaning discs to be of much value for preventive maintenance since they may just move the crud around. However, for pure non-greasy dust (no tobacco smoke and no cooking grease), they may not hurt and could even do a good enough job to put off a proper cleaning for a while longer. However, it's also possible they will ruin the lens. Consider that the worst thing to do to a precision optical surface is to wipe it with a dry cloth as this is likely to scratch the surface as it rubs the dust over it. To the lens, a speck of dust is like a boulder. Once the lens is scratched, replacement of the entire optical pickup is the only remedy. And, since there are absolutely no sorts of standards for these things, it is possible for a really poorly designed cleaning disc to damage the lens even if the dust itself is non-abrasive. In addition, if the cleaning disc doesn't look like a CD to the optical pickup or disc-in sensor, the lens it may not even spin. So, the drawer closes, the drawer opens, and NOTHING has been accomplished! (But at least no damage will be done.) As if this isn't enough, NEVER put one into a high-X CDROM (DVD player or DVDROM drive). The high speed rotation may cause the cleaning disc and/or player/drive to self destruct. And, don't try a cleaning disc on an automotive CD player that sucks in the disk - it will get stuck.

How do i repair the no disc display


The first check should be by inserting an other know good disc into the tray, and attempt to play it. If it does, or do not, make sure that the laser pickup unit to to set is faulty; and have to be replaced. An other possibility is improper disc loading, due to faulty loader mechanism and with a faulty sled motor. Contact any service technician in this case. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

My bang & olefson cd 50 will not play. hear "spinning" sound when disc inserted.


THE CD50 DOOR MECH IS BELT DRIVEN IF THE BELT IS WORN THE DOOR OPEN/CLOSE SWITCH WHICH IS TRIGGERED BY THE MAIN CAM UNDER THE MECH MAY NOT BE FULLY CLOSED OR THE SWITCH MAY NEED CLEANING,ITS A LEAF SWITCH.THE MOST COMMON REASON FOR THE DISC TO SPIN BUT NOT READING DISC IS DISC MOTOR NOT GETTING UP TO CORRECT SPEED.IT CAN BE REMOVED,DISMANTLED AND LUBRICATED BUT CARE MUST BE TAKEN TO MEASURE THE TURNTABLE HEIGHT,BEST MEASURED FROM THE BASE OF TURNTABLE TO CHASSIS WITH FEELER GAUGE,CAUTION THE MOTOR SHAFT HAS SEVERAL VERY FINE WASHERS INSTALLED DONT LOSE THEM.

When I insert a disc in my hi-fi it reads no disc


Hello
The problem may be due to its Laser Pickup Unit itsef. Just put any other good CD, which was played with this set earlier, and see whether it ireads the xisc and starts to play it. If not, put in a lens cleaning disc {which can be bought from most of the electronic spare part selleing shops at your town, and won't cost more}, play this disc at least three times, by ejecting it out from the set, and reinsert it in to it each time. This will clean the laser pickup unit's lens. If the fault is due to accumulation of dust or dirt, this will help you. If not, there is no other way than replacing the Laser Pickup Unit of the device, with same type and number. OK.

Displays no disc when Cd is player


Hello
Put it an other good known disc, which the set has played without any problem at all. If it also doesn read it, and displays no disc, the Laser Picku unit of your set has damaged. Put in a lens cleaning disc into the player, and play it for at least three times. If the fault is due to accumulation of dust or durt, the cleaning disc will clean it, and your set will be OK. If not repalce the Laser Picku Unit, sith same type and number.
The lens cleanig disc can be bought from most of the electronic sparpart selling shops at your town, and won't cost more. OK.

My CD player keeps displaying no disk and wont play the cleaner disc, is something dirty or broken?


Hello
If it does not play the cleaner disc, just inspect whether the disc inserted in spins inside it. You can check this by open the upper cover of the player, and inserting a disc into it. If inserted disc spins inside, and the player won't read it, the fault is with its laser pickup unit, and it should be replaced with same type and number.
If the disc dos not spins, the fault is with the sled motor [the motor that spins the inserted disc], has damaged, and should be replaced. OK.

WON'T PLAY CD'S READS "NO DISC"


  • Check the disc you're using for scratches and dirt. If the disc is damaged it won't play properly, regardless of the CD player's ability to function. You can use a CD repair device like the "Disc Doctor" to repair the CD or purchase a new CD.

  • Clean the laser lens with a CD laser lens cleaning disc. CD laser lens cleaning discs can be purchased at most electronics retailers or online. Insert the laser lens cleaning disc and follow the instructions.

  • Insert a correctly-formatted, undamaged disc into your player. Listen to see if it begins to read the disc. If it continues to make no sound and gives you the same message, then the problem is probably that your disc is not spinning in the device.

  • Clean the lens while the DVD player is open. A dirty lens is most likely the cause of your no-disc error. The lens should be cleaned with isopropyl alcohol and a cotton swab.

    RCA RP-9515 stereo, CD player won't play


    RD probably stands for "Reading Disc" and ND probably stands for "No Disc". If the CD player doesn't recognize any discs, then either the laser is dead or the motor has died. MOst likely you will have to replace the unit.

    The "no disc" message will show up any time the unit tries to play a disc and fails. This can be because the lens is dirty or the optics have failed. Try opening up the unit and cleaning the lens using a cotton swab and alcohol. If that does not resolve the problem, the optics are failing and will need to be replaced.
