Hi there and welcome
Can you remove the battery please then hold the shutter button down for 60 seconds then release.
Wait 5 minutes, put the battery back in and try to turn it on.
Tell me please if it now starts
Is the red light still flashing?
If you put the battery in the charger, does it show it as charged?
It is the internal mainboard that has faulted.
A corrupted firmware can cause this. But we have ruled this out by trying to hard reset it.
I am really sorry about this and you are going to have to return the camera to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
You have already paid the deposit which was for the service I provided to go through all possible causes and rule them out to confirm the problem.
This is what we did and what you paid for. If we were only paid for fixing an issue, no one would have taken your question due to the possibility of it not being resolvable.
You now have the issue confirmed and know what you need to do.
We operate on trust here, so if you still want a refund after receiving the service, you can get one by emailing***@******.***
If you need anything else, please let me know
