    Would you know how do I remove the lens parts? My zoom is broken and I can find new parts on ebay, but I don't know how to remove and replace it. Thanks!

During my vacation two capicators on the motherboard failed and 'exploded'.

I've ordered the motherboard and replaced it exactly as described here. Thanks for the explanation!

But since I've replaced it, I have autofocus problems, the camera isn't capable to focus, especially in wide zoom.

Is this something that needs to be calibrated or something?
