E18 is lens error. When the lens will not retract and camera is not functional (no picture on
display, and does not shoot) , and you already tried replacing
batteries with a new fresh set (ensure please) , and then restarting
camera with no memory card inside, then camera is faulty.
easy fix by pushing gently the lens (do not force them, just help them)
while you turn off camera at same time. Try also switching the mode
If still no luck , then the camera must be disassembled to fix the problem.
Possible reasons are :
- Faulty lens mechanism or jammed lens (camera usually turns off by itself in this case)
- Main board faulty.
- Ribbon cable to main board broken or connector defective.
- If there is no power at all it is the connector from batteries to main board, this is also a ribbon cable.
If the camera is less than one year old will be replaced by manufacturer.
