Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers and other electronics. I have been a photography enthusiast for more than 30 years. . It would be my pleasure to assist you with this.
Please check for this:
The camera has two micro-switches to verify that the (a) memory card door and (b) battery compartment door are fully closed. There are some tabs on the doors which push on the respective door switches. Check to make sure your doors have a good fit and that the tabs aren't damaged in any way are able to close completely.
Please let me know the results.
If the switches are not engaged then the camera will not power up.
