You can google and find a variety of relevant links.

E.g.: https://www.youtube.com/watch?v=uLCbQ4A5m1U

You should watch a few of them first..... no warranty or guarantee the the procedures offered will work and/or not cause damage.

However, I would start with your User Guide and a visit to Canon's website.
