Tried hitting the reset button. Is there just a blank image when trying to turn on the calc?

Yes it doesn't turn on at all all there is is a blank image

Have you also tried new batteries?

Try to force your calculator into "OS Error" mode :

• press and hold the restart button on the back
• without releasing it, press and hold the [F2][4][AC] keys
• without releasing these 3 keys, release the restart button
• now only release the [F2][4] keys together
• wait a second
• now finally release the [AC] key
• press and hold the [9] key
• wait a second
• release the [9] key
• press and hold the [×] key

If the calculator turns on and shows you an "OS Error" screen, then it's not broken and you just need to reinstall a compatible OS.
