Canon Rebel XTi wont power on

[tinalwrn]

Rebel is 3years old.
Went to start shooting baseball game and nothing....
No power...no lights, no motor, not even a flash or blink.
I have tried:
new batteries
start up without the lense/CF card
start up with a different CF card
connecting to the laptop
cleaned the battery, the CF card and the AV oupt doors and inspected
jiggling the on/off switch
jiggling the camera mode dial

Still nothing?
Any suggestions.
My thought is the power board.
