Are there such situation(s) that can cause a camera (can be a point and shoot camera or a DSLR Lens) Lens to lose its image stabilization ability?

For why IS may appear to not be working you may also want to look at: photo.stackexchange.com/questions/6039/… and photo.stackexchange.com/questions/8803/…– forsvarirJun 12, 2012 at 7:06

@Miljenko -- rather than commenting (which adds noise) you can edit the post to correct obvious typos.– mattdmJun 12, 2012 at 10:53

2Is this theorectical, or are you trying to troubleshoot a problem?– mattdmJun 12, 2012 at 10:54

@mattdm: I recon this to be more polite. But noise-wise, you are right, and I'll do that in the future.– Miljenko BarbirJun 12, 2012 at 12:19

1@Miljenko -- on this site, just fixing simple problems is more polite. It's different from a typical forum, in that the goal is to collaboratively create the best possible questions and answers.– mattdmJun 12, 2012 at 12:23

If you're talking about lenses permanently losing their stabilisation ability this could be due to any of the following factors
- failure of the switch which activates IS
- faults of the motion detection sensors
- failure of the control system
- failure of the IS motors
- jamming of the IS lens elements
which in turn may be the results of
- manufacturing defects
- physical shocks to the lens
- moisture or water damage
I assume the optical IS function that is built into lenses is micro-gyro based, not image movement based, and so may be affected by a strong magnetic field.
Also, dirty contacts can cause all sorts of errors.
