powershot sx 530 flashing indicater light

[greacia]

When I turn on my camera, the lens protrudes a bit, and the indicator light flashes yellowish green, and all camera actions ceases no matter which button I press.  Sometimes I get an error code of 42, but usually the camera turns itself off.  Can anybody give me an explantion as to what is wrong and what if anything I can do to fix the problem?  Thanks in advance of any advice.   judy

A short search indicates the following for your error code 42:
This usually only happens if the camera is dropped or if the camera has previously been taken apart. The shutter could be manually opened, freeing the hinges; however, this may not fully fix them. In this case, the camera may need to be taken apart so that the shutter hinges can be cleaned and realigned.
