Its a compact camera from the 1990's.
Low/weak battery, trash blocking the lens door, trash in the film compartments or a major motor or electronics failure.
Common household dust can build up and block the lens door from opening fully, paint chips or small pieces of film can block sensors in the take up compartment, corrosion on the DX can prevent them from reading the film cassette.
Blow it out with compressed air and clean the electronic contacts with a pencil eraser or similar. Replace the battery with a name brand fresh one.
I would be interested to hear how any electronic device can provide an error code indicating it's battery has been installed incorrectly but that would surely hijack the thread . . .
Early camera electronics did not have a blocking diode to prevent damage to the camera circuity if the batteries were installed incorrectly then camera manufacturers started including them in circuit design.
An extra diode that blocks correct polarity will pass incorrect polarity which then can be connected to an error light/lcd readout with minimal circuity involved and very low cost. Especially useful when targeting the amateur/advanced amateur market.
Hi guys, thank you all for the messages, I have been on hollidays and not be able to answer. But coming back I check the bateries and is not that. I got new ones and it s still "error 9". When I put on the camera instead of getting out the lens (as before) I can hear a very low sound as if the lens would ty to get out but it is jamed. The front cap when moved with the hand opens.. So I am guessing is a mechanical problem of the zoom lens??
Well you have a bad camera. Remove the batteries. Remove the screws on the back of the camera. Gently unsnap the back shell from the front. The shells use a latch system that gentle prying between the two sections will release the latches while brute force will crack or break something. Some latches have to be pushed inward to release while others will release with slight outward pry.
Once the back shell is off ensure nothing will short out and reconnect the battery. Power the camera on and check its operation.
Possible causes of the failure are 1. poor electrical contact at the battery compartment from battery leakage that may require replacing the wire; 2. sticking or jammed lens movement from heat warpage or bent/broken mount from being dropped; 3. bad lens extension motor; 4. bad electronic components.
Thanks shutterfinger! It s not the battery leakage (I checked) so, I think I'll get it to be repared, I now nothing about reparing cameras or electronics
