Originally posted by Pentaxacapture The wheel is not stuck at 125x mode but in AUTO and M modes, the mechanical shutter sounds the same (1/125 seconds) all modes, expect in B mode. There is no life in the LED displays in either AUTO or M settings.
New thought - this is exactly what my ME sounded like when I last took the batteries out. You've told us yours are fresh. So for your camera,
either the electronics are dead,
or power is not getting to them for some reason. If it's the latter, the fix may be easy.
You could try looking at the cap of the battery compartment - my P3 (which I inherited after years unused in a cupboard) had shut down because corrosion had interrupted the circuit, and a little bit of gentle scraping right in the middle with a flat-head screwdriver fixed that and brought it back to life (something which has repeated itself at least once since then, with the same simple cure).
Barring that, you are looking at professional diagnosis and repair.
