RX100 III switching itself back on after my powering off

[Whitesocks57]

I'm going to throw myself on the mercy of members here. I have researched my problem online before coming here and all I can see are a range of similar people having this experience to which the responses are "Me too" which offers no comfort or solution.

My RX100 III was working perfectly until a few weeks ago. I'd not used it for a couple of weeks and then this thing began. If you power off, it will turn itself back on, the lens extends and it stays like that and I guess flattens the battery. If you power it off manually, it will turn itself back on after maye 10 or 15 seconds.

When it is on, I can no longer use the NFC feature to transfer images to my phone. It just doesn't register. 

My software version is 1.2 and I can't see any benefit of installing version 2 as the update is to do with using the camera in a waterproof case, which I don't do.   I've been a Sony nut for years, TV, Hi fi, phone and cams.

In the last 6 months both the RX100 and my lovely HX400v have developed faults. 

If I find some good advice for this problem, then I will open up a thread for the 400v another time.

I really do appreciate any input as I can't afford to send it off to be looked at. 

Regards  Keith

You might as well update the firmware, it might fix whatever is going wrong.

Have you tried turning the camera off and removing the battery for 5 minutes of so?

Have you tried a new battery?

If none of that solves it then sending it to be repaired is the only option.

Thank you for the response.

Before posting, I'd tried everything. Since posting, I have I believe, solved the problem. I read as much as I could find and one article said when attempting a firmware update, remove the SD card. I'd never done this. I went through the update process for the umpteenth time and this time it worked. Took about 20 minutes for the update, but I've had no more trouble since.

I hope the soultion I found is of some use to others with this annoying problem.
