Canon Powershot G9 Does Not Turn On

Howdy! I have a Canon Powershot G9 that will not turn on.

I've heard of the issues that people have had with the DC/DC power board, and that seems to be the most common reason for them to break. I ended up replacing my DC/DC board, but still no luck.

Cleaned the contacts of the power button, nothing.

What should I try next?

Thanks
