Originally posted by Senseicameratech I can say I know of problem like this one and solution. Mostry 1 of 2 things causing.
SR mechanism driven by many magnet that is very strong. Sometime USB connector pushed too hard and become loose from circuit. Since it metal it become wedged in SR from magnet. This result in SR mechanism become blocked and do not stop moving. Also, sometime screw from inside become loose and cause same problem. Most time can repair and not replace SR/sensor.
I have the same problem, but I don't using USB connector (I just taking out the flash card).
If that just electrical magnets then I think it possible to fix problem via taking out the battery for a long time?
