Hi, Click
this link for more info. Hope I
helped you.
If you have necessary tools and test instruments, know safety precaution in
basic troubleshooting try the steps below to solve your problem. I've suspected that you're spindle motor (Steps #3) is already faulty. Below is the steps that will guide you fixing it yourself.
Assuming that the disc is good.
1.Clean the lens. -
Sometimes because of dust and any fine foreign objects the lens can't read any
disc. If you have a CD Lens cleaner, play it to the affected area. 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. 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 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.
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.
Have a nice day!
Thanks for using Fixya.
