PowerShot SX720 HS Will not turn on

[Cyrus17]

My brand new PowerShot 720 will not turn on - battery is charged 

I already returned one because it wouldn't turn on.  What to do?

Update: It's been almost 2 months and I'm still doing my happy dance. My PowerShot SX720 HS still powers on without any hiccups. Try DIY solutions first before sending in to Canon Repair. Save yourself some big bucks. Yippee-Ki-Yay!!!
