Hi!
Ok, I have now two defect Canon lenses: EF 24-105 f/4L and EF 100mm f/2.8L IS.
Both having same symptons: When attached to a body, IS unit starts keeping tickling/rattling noise. As I turn on the power, same noise continues and also aperture value on upper LCD screen is blinking beetween f00 and f2.8 or f4.0.
I think it is caused by defect image stabilizer and if so, what is the actual reason within IS unit for this kind of behaviour?
What makes it more interesting is that aperture value keeps blinking/looping even if I disconnect IS and diaphragm units from the PCB!
I really want to repair these lenses by myself, I have fixed at lest 50 lenses (mostly AF and aperture problems etc), so I know what to do. These IS units are just new to me
