until (hopefully) the lens motor springs into action and pushes the lens out.
If unsuccessful, or if the power light isn't even coming on when you press the power button, the camera will have to be returned for repairs.
However, since that model was introduced 4 or 5 years ago, it's likely it's warranty has expired so repairs will not be free. Get an estimate for the repair cost if you can because it might make more sense to buy a new camera instead.
I forgot to even mention the battery -- It may simply be a flat battery so make sure it is fully charged up then try using the camera.
