Hi markcurto!

Thanks for posting.

Does the BUSY message appear only after performing a certain action, like pressing the SHUTTER button?
Is the built-in flash popped up when you see the BUSY message appear?
If you press the PLAYBACK button or the MENU button, does anything appear on the LCD?

If this is a time sensitive-matter, additional support options are available at Contact Us.

Hi Mike,
I am having the same issue. Error 99 used to pop up, but doesn't anymore, just what the previous guy said happens.
It only happens when I push the shutter down, the flash isn't up and no button will turn on the back LCD.
