Hi, problem can solved. since you said motor is fine, that means the lens is bad and will need to be replaced.

When a lens light does not indicate, lens will not function.

If the lens was showing light and doesn't play, you can say it needs cleaning. But in case not light indication. you will have to replace the lens.

Take it to your nearest repairer if you can fix it your self, to prevent further damage.

Take care.

Disc inserts and ejects with no problems but once inserted, the disc will not spin. Laser mechanism thumps back and forth trying to read disc. Play indicator light blinks on a 50/50 cycle.


Hi tiro079,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust and any fine foreign objects the optical lens can't read any disc. If you have a DVD Lens cleaner, play it to the unit. If this is not available you may manually clean the optical lens. Open the cover and gently clean the eye of the lens by smooth,clean,soft cotton buds. Be careful while doing this, just a gentle stroke only.
2.Check the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc, this is because of the movement of the optical lens back-and-forth. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the spindle motor - Check the spindle motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.

Hint : Most of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.


Hope I helped you.
Have a nice day!

When putting a disc in, it attempts to load and makes a noise then reads "no disc". When checking it further with the lid up, the disc does not spin but the laser light does come on.


The pladder motor that the dvd sits on has an open winding in the motor, or the 5 volts to the motor is missing. Unfortunately it will be far cheaper to replace the dvd player than having it repaired.

DVD player will not recognize any DVDs I put into player. I even took top off and cleaned laser eye and still does not play. Now red light is on in place of green power light. What's up with this thing?...


No disc error can be a DIY like the following steps.

Assuming that the disc is good.

Since you've already done the #1 now proceed to #2.

1.Cleaning the lens. - Sometimes because of dust the lens can't read any disc.

Try clean the lens by soft cotton buds. Be careful while doing this.

2.Replacing the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser.

If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.

3.Checked the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.

Good motor - reading should be fairly high and it will spin.

Bad motor - reading will drop to low resistance and will not spin.

If you already cleaned the lens, and confirmed that the ribbon is good as well as the motor then I've advice you to send it to repair shop because the next step should be done with an expert because it is quite technical diagnosing the fault between the pick-up lens and the main board.

The CD player will play some purchased CD-s but will not play others. The ones that it will not play do NOT iniate the disc motor but a click is heard and the display reads NO DISC. I have cleaned the...


If you can disassemble the CAP(disc holder) and place it on the disc while it is on the spindle and at the same time push the (hidden)lid switch you will see the lazer"s lens move up and down while trying to focus on the disc. If the lazer see's the disk it will tell the motor to turn. If it dosn't see the disc it will not turn the motor. Some model will kick the disc to spin a little while trying to see the disc. This type of player can be tricked into seeing the disc if you spin the disc a little by hand when the lazer's lens is moving up and down. At that point in time it might see the disc and take over the motor and spin up to normal speed. If the disc is an illeagal copy sold as a original the quality of the disc could be the cause. If the player is very clean (no small hairs stuck to the glue that holds the lens in place) (never clean with a cotton swab, use a shammie swab with rubbing alcohol or isopropal 99%) the problem could also be that the lazer is just not strong enough and the whole lazer-motor assemble should be replaced. Older units could use 1 drop of light motor oil on the motor shaft at the bearing to help start the motor when the system kicks the disc to spin. If the player reads the disc at the time you manually spin the disc maybe a good cleaning and oiling is all that is needed. The disc spins clockwise. if the disk spins counter clockwise replace the whole assemble. Maybe simpler, just give the disc a good clockwise spin and quickly close the door and push play while the disc is still spinning. if it starts, there you go. Don't use caned air on the lazer assemble. it will blow the dirt further into the lazer mechanism under the lens and make matters worse! Good luck!!

Sony 5 disc dvd player - discs lock in - spinner needs push to go


You can spray WD-40 contact cleaner but very little amount in spindle motor (you call it spinner) and please take care, DO NOT spray over optical lens which is so close to spindle motor.

If problem still exist, you need to replace optical lens assembly and I will provide you part number if required.
Good Luck.
