How do i replace internal battery on the minolta
Unscrew battery compartment on the right grip, and remove the battery holder (AAA's in most Maxxum 7000's) In the compartment you should see a silver colored metal plate, held on by 6 small phillips screws. Unscrew these, and carefully lift the plate, and move it aside (there's a tiny wire soldered inside the plate, so don't break it off).
Inside there should be a CR2016 lithium button battery. Replace it, and reassemble in reverse order.
NOTE: This probably won't fix any issues regarding the removal of the film, as the 2016 is just a memory backup battery for when the main batteries are removed.
to remove the film, install fresh main batteries, turn on the camera via the "Lock" switch and rewind the film. on the back of the camera, just behind the LCD screen, above the film door, you will see a grey button marked "R". Push and hold it, while sliding the gray slide switch immediately to the left of it to the left. The film should now rewind.
When the film is done rewinding, open the back via the sliding latch on the left side of the body with the gray button in the middle. Push the button, while sliding the latch down.
To insert film, place the cartridge in the same place and orientation as the old roll, and pull the leader over to the red dot on the bottom right of the film compartment, and close the back. it should advance to the first frame if done correctly, or blink 0 if done wrong.
