Error 99 How To Check For Shutter Failure

[RaoulIsidro]

Error 99 could mean anything. The internet is awash with procedures on how to deal with it.
This thread is to check if Error 99 indicates shutter failure.
This test is for cameras with the Live View function only.
Problem: The camera, after being turned on, keeps on locking up after the first shutter actuation and displays Error 99.
Turn camera off.
Turn On again.
Press Live View button. Is the screen black but the indicators and AF points work?
Turn camera off.
Remove lens.
Turn camera on.
Press Live View button.
Can you see the sensor? (it will be greenish in colour) or can you see black matte? (the shutter curtain in closed position)
If you see the sensor, it is not the shutter causing the problem.
If you see black matte, it is shutter failure.
Hope this would be of help for Error 99 events.
