This is lovely, my Canon XTI won't power on. And I must have this camera for a scheduled photoshoot next weekend. I bought it 2 months ago from Dell, it's worked beautifully until today when I went to use it and now it won't power on. I have 2 batteries, so I took the other battery I had on the charger off and put it in the camera and same thing. I flip the switch on and nothing, every now and then the power light will blink once but that's it. Anyone with an XTI experience this?
