The Lumix LX2 from Panasonic is (almost) the same as the Leica D-Lux 3. I bought this camera some days after I had bought a Lumix LX-3. It was offered with a defect. I was able to find the internal error message*, but I have no idea what that means. I think the sensor is broken. It does not display an image on the screen, but the menu works.

* - 18000300: ENC1 detect error (C.B. motor encoder 1 detect error) FP9001-(5) signal line or IC6001 (VENUS 3).
