My camera led light is on but can’t turn it on

@brucewadnizak common issue for this could be a stuck lens. Take a look at the front and see if your lens appears cockeyed. Try something like suggested on here Ultimately it does sound like it's time to open the camera up and to take a closer look at the power board, battery connector and DC_DC board etc.

Use these guides Samsung ST150F to work on your camera and check this Wiki Samsung ST150F Troubleshooting for further troubleshooting.
