Lens wont retract so camera turns itself off

If the lens will not retract, and you cannot get to the menus, you need to have it repaired or sell it for parts on a site such as Ebay.
Since it is not working anyway, you may want to try the following, be warned that it can cause more damage, as the camera turns on, push on the lens in a gentle twisting motion. Do this until you see it retract, or it will not fix. At that point, you have to make a decision.
