Some time ago, I was disappointed to discover that my LiteTouch AF600 would no longer auto-load film. Reminder: like many P&S, this camera is supposed to auto-load and wind the film to frame 1 as soon as the back door is closed. Opened camera shell: nothing obvious, except one broken latch piece fell off. Careful with the flash capacitor; better to discharge it with a 1k-ohm resistor. Re-assembled, hoping the broken piece had jammed some film advance gears; no joy.

Then started tinkering and found the following. Power the camera ON with the back open. Install film leader as per instructions. Fiddle somewhat with the film, pulling away then back onto the film gate, sliding right-left. At some point, the winding motor wakes up. Close back door without delay; camera winds to frame 1. From here on, behaves normally.

Glad I found this workaround; was not ready to buy another AF600 at current (gasp!) prices. Still wondering about the root cause. Corruption of firmware code seems unlikely. On the other hand, the camera µcontroller definitely has some persistent data. During my tinkering, at some point, I removed the battery during powered rewind; when I re-inserted the battery, rewind resumed.

Would anyone know how to perform a full reset of this camera? I already tried powering on while another button (flash mode, timer, shutter) is kept pressed. To no avail.
