SOURCE: moultrie I40 getting error code 480 and wont go into auto mode

I lightly dropped my I40,about 24" off the ground,in grass.Thought I broke it.I had a 480 code. Opened battery compartment to reset and that fixed the problem.If your lucky this will fix alot of your sensitive electronics. Kill the power for 10 seconds or so and your cured.

Does the flash work? Could be flash circuit or day/night sensor.If you have another D40/D50 camera that flash works but has other problems,swap out the sensors.If not the sensor but the flash circuit then most likely one of the large charge capacitors which has to be soldered in.I use a digital multimeter with I/O capacitor test function..these caps should be about 250mfd.
