Hi dear awesome Guide writter,

I have used the guide on a similar model, the Casio Exilim Z77 (if i am not wrong), in a context where sand and dust were disturbing the mouvments of the lens.

Most of the steps have been simulars. I additionally open the lens were most of the sand had entered.

After my first try yesterday evening, the canera refused to switch on again...

I will re-open this evening to see if any module appear disconneced from the other.

Do you have suggestion how to proceed ?

I have only simple iFixit tools, but no voltage or current measurment (yet).

Best regards,

Michel.
