Before you attempt to repair your DVD Player yourself, make sure that you have necessary tools and test instruments like philips screw drivers, multimeter, soldering iron, soldering lead, soldering pump, etc...
This is a DVD/MIDI Player with a "no disc error
" upon loading any disc that played before...
Watch this VIDEO
First I've loaded it with disc and observe the movement of the optical lens and the spindle motor. First thing I've noticed that the spindle motor
upon spinning and it's spin slowly
unlike the normal RPM...
I've suspected the spindle motor was already bad but still to be confirm...
Unscrew the disc holder plate from the assembly to keep away the magnet touching the spindle motor, this may affect the reading and spinning of the motor upon testing with the multimeter.
This is how it looks like after removing the disc plate holder in the assembly. Spindle motor is secured with 2 small screws in the lens assembly.
Pull-out the connectors from the main board to see the underside of the tray.
You may test the spindle motor with your multimeter set in resistance measurement (ohms X1
) even connected to the small board.Bad motor
will read either less than 5ohms(shorted winding) or infinity (open winding) and will not spin.Good motor
will read more than 50 ohms(depends the size) and will spin upon testing. Watch this VIDEO.
Onced you've confirmed that the motor was already faulty, unscrew it from the lens assembly.
Replaced the spindle motor with new one. Before you install the new motor make sure that the clearance of the disc holder
is the same as the old one. Compare first the clearance because if it is to high the optical lens will not read the disc same if it is to low....
After replacing the motor re-insert all the connectors to the main board.
I've load same disc which does not read a while ago and observe what will happen. Observe the disc and the sound oscillation
from the spindle motor in this VIDEO.
Hope that the above information, pictures, and video will help you fixing your DVD player yourself.
Thanks for visiting Fixya.
Have a nice day!
