A DVD player that does not play CD’s repaired. Model: Hemilton

This is a China made DVD player that was brought to my shop with the problem it does not play DVD’s.

When I hear such kinds of symptoms in a DVD player, a few things come to mind. The pickup LED is not working or the spin motor is not spinning. There is only one way to find out which one is causing this problem. Let us begin.

dvd spindle motor

The customer explained that when powering the DVD player, they only see the logo of the DVD player. There is a message on display that is it loading but there was no loading taking place. I powered up the DVD player and played a movie in there but the DVD movie was just sitting there and not spinning.

 

I gave it a push with my finger, and it started to spin and I could see a movie starting on TV. It was clear to me that there is a problem with this motor and it has to be replaced.

It is very easy to replace the motor. Only three tiny screws holding the motor to its stand.  Once these screws are off, the motor is loose.

This is the spinning motor from beneath the board. It is a 3 volts motor and as you can see, the part number is written on it. From experience, it is better to replace it with the same exact specification and part number otherwise you will face a problem.  That will save you time and effort.

It was an easy job replacing this motor. As I said before, about three screws and I were able to replace it with a new motor. I soldered the red wire to the positive and the black to the negative and gave it a try.

As you can see in the photo, the DVD movie was spinning and when I checked the display on TV, the picture was not clean. The picture was distorted. There was one thing left to do and that is cleaning the pickup LED. Once I did that, the picture was clear and it sounded even better. Mission Accomplished.

    Waleed,
    Good ,Waleed can any 3V spindle motor will do ??.... i saw many technician in india are just mach the motor physically for proper fixing the screw posision and they replace.when i asked to shop owner of spare parts he said many china make DVD player exact parts are not available so they are using this trick.

      Yogesh: no all the motors have the same voltage rating. you have to match the voltage rating other wise it will not last long. that is why I never throw any parts away. I keep them for future use and if I do not find it I buy it or order it on line.

        Hi everybody, here in my country we use the motors of CD/DVD tray of the optical units of PCs, and they last a lot. Why don't you try it on with this?

        Hello Waleed, there is one thing missing in your explanation. Please explain how did you determine the height of the disc holder, after installing new spin-motor. Thank you for the answer. Milos Nikolic.

    Thanks Mr.Waleed for the Article.am working on a Vcr the problem is the spin motor works (spins the cd) for a very few seconds then stops.your idea on this will be highly appreciated.Regards.

      Joshua: you are most welcome. i am confused, are you working on a CD player or a VCR? I guessing you are working on CD player. any way, check if you have the right voltage reaching this motor. or it might be a bad motor. try spin it with your finger..it a free spins or it stops soon. if you an analog multi meter, use the X1 setting to check the meter. of course you have to disconnect it from the board to check it.

    nice job Waleed...i am amazed your supplier has the motors at all - presumably damaged motors happen often?

      Moshe: thank you. well, it depends on the brand name DVD players. some models, the motor dies fast and others do not. I have replaced so many of them so far.

    sir,
    i owned a dvd player in which optical pick up sf hd 65 is used. I purchased a new and replaced it. but I noticed that when loaded cd/dvd the pick up coil works but there is no laser produced. I checked the laser diode also. but the same is in good. there is a voltage regulator with 6 pin. but i dont know the pin details. can you send me a circuit diagram for optical pickup sf hd 65 for dvd player. Thanks a lot for your free repair guide postings sent till now.
    I once again thanks.

      hi, did you neatly remove the soldering lock from the lense assembly ? Also you try replacing the ribbon cable that connects the lense to the main board.

    Hi Waleed,

    Nice article that's great to replace the motor but it takes a lot of time and money in traveling back and forth. We use to check the resistance of the motor terminals it should be around 20ohms if not spray a zurich or WD40 anti corrosive liquid at the contacts or carbon brushes then give some drive as per specified voltage of the motor in either direction a couple of times ( similar to cleaning the contacts of a relay) and then connect back to the original position . The motor works eine . This problem arises due to non usage of the player for many days and thats why corrosion occurs in cotact areas and 3v is very less to start the motor.
    We use to do these tricks with all our sony products when i worked for sony once upon a time.

    Best Regards

      Anand: thanks for sharing. yes, totally agree with that but sometime even if I spray it but still does not work, the only way to solve this issue is by replacing with a used or new one. I am working an LG DVD/VCR machine right now and the motor is not opening the CD tray and it is not loading the way it should be. I sprayed all kind of stuff on it and nothing worked. so I replaced it with a new one, and it is working like a charm

    Dear Tony,

    First of all you check the display on monitor ,if display is ok then most probably BIOS program of your motherboard is get corrupted and i request you if you are familiar with the repair process then go ahead and check the RAM on motherboard but my suggestion for you to let this thing handle by some professional.

    Thank you for the nice article.

    I have across this problem many times and it remained unsolved. Now I can fix a no spin problem

      Tarning: first you need to check if the motor is getting the right voltage. the voltage rating is usually written on a paper on the motor. check how much voltage you are getting there. if no voltage traced it back to the source and find out why there is not voltage coming out. sometimes, the motor itself is shorted and taking the voltage down. isolate the motor and check again. if voltage there when the motor is not connected, replace the motor.

    Thanks Waleed for sharing... I had a problem with a DVD player, actually I still do.. The DVD player was suffering from no power symptom and I manage to solve that problem but when I tried playing a DVD some times it would work and sometimes not. I had diagnose the motor was the problem and I just cannot get the motor to buy. Any ideas?

      Andre: you can order it on line from Ebay or simply just get a use one from any dvd player that matches the specs of this motor you are replacing.

    Wow! this is another great article Mr. Waleed Rishmawi. i had many of such problems brought to my small workshop when i was in Zambia, since i was just beginning practicing electronics i was not able to tell what could cause such symptoms like No Disc, continuous Loading, etc.
    tell you what, through this website I have learnt a lot! keep us updated!
    Mission Accomplished Indeed!!!

    have only replaced 3 spindle motors in as many years, lucky...

    fill them with servisol switch cleaner aerosol, run at 3v then run reverse polarity, not forgetting to isolate from motor drive circuitry or remove motor.

    i do increase voltage sometimes up to 6v or 7v for very short bursts and on reverse polarity. many have been fixed using this rather crude method.
    after this i clean again with servisol spray and allow to dry out after using compressed air from aerosol.
    never had my customer return (yet)
    Yes better sometimes to replace motor.
    Also works with battery operated razors etc

      Trevor: thanks for sharing. it seems like it is working fine since no one returned the machine back. i will give it a try next time although I still the like the fact to replace it with a new one.

    thanks every body in this forum there is a trick about the spindle motor
    First remove the cable positive and negative connector from the board and check through multi-meter if you are getting resistance of the motor put in power supply 9v dc but don't take a long time like only 5sec the motor will spin fast and reverse the polarity,do it 6 or 8 times then put it back to the main board the motor will be fine. i did always like that in my repairing try only this one if you cannot find the spindle motor in your place Thanks to Mr Waleed he is right its better to replace new one
