Wrong disc/No disc error can be a DIY like the following steps.
Assuming that the disc is good.
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.
Hint : 50% 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.
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.
Thanks for using fixya.
