"seems like a sensor in the optics don't have connection to the mainboard anymore or intermittent connection. Probably because some soldering has shaken apart.
the Zoom Lever Spring of my Canon PowerShot G7 seems to be broken since yesterday.
i assume it's not about some soldering – opened the camera and saw that the spring beside the lever is loose; didn't disassemble the camera further because i don't have an idea how to lift the top part with all the knobs – had anyone else fixed that issue?
