The zoom does not respond

Hello. The stuck lens assembly is triggering an error condition--and you get the "press reset" to make you reset the internal computer in the cam. Was the unit dropped or did it have some sort of impact--this would cause the internal lens mechanism to become mis-aligned. Also, leaving the cam in a hot car can cause grease(or other lubricants) to flow to movement surfaces, thereby causing a "glue" effect. Look into the lens(cam off) under a bright light and try to determine if the internal lens assembly is crooked. Also, try to see if there is any "wet" area appearing anywhere(especially if the cam was exposed to heat--classic symptom) If the lens assembly is indeed mis-aligned, the cam must be sent to a repair facility. (Also, make sure the battery is fully charged as a weak charge will cause lens jamming(and a whole host of weird phenomenons)---Rick
