The battery check light and signal are worth little other than to check
if there are batteries in the camera. The problem is that it doesn't put
a load on the batteries. By far the most common cause of this problem is
low batteries. As they age and lose the ability to deliver the required
amperage without losing voltage, the camera senses when the exposure
cycle starts that the voltage is too low to assure an accurate exposure
- and intentionally locks up, the REAL battery test.
This is an especially bad problem with any battery other than silver
oxide ans still a problem with EPX76 batteries, which have a very long,
gradual voltage curve with use.
To reset, looking at the camera from the front, on the lower right side
of the lens mount, there is a tiny button. Push that in and rotate the
shutter speed ring to the red 60 or B setting. That should drop the
mirror down and reset. It may well work again until the battery gets
tired again, then lock up again.
As I said, this is a very common problem, but if a reset and healthy,
new batteries don't fix it, you could have somethign more serious.
