Hello and welcome to JustAnswer, I look forward to assisting you today. How old is the camera?
Do you have it connected to the computer while trying to turn it on?
I have found others that have had the same problem with this camera. You may want to try warranty service by going to this LINK. In the mean time, you can transfer the photos by removing the memory card from the camera and inserting it directly into the camera.
Okay, just wanted to make sure.
Are you able to transfer the photos from the memory card by inserting it into your computer?
Please let me know if I can be of further assistance.
