Hi, thank you for contacting My name is***** will do my best to provide the right answer to your question.

Spontaneous changing of the mode of camera operation, may be a symptom of either poor power supply to the camera's control circuitry, or static discharge into the control circuitry having disordered it somewhat (or more than somewhat), or simply aging circuitry losing its excellence of function.

Try removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera again.

Then try cleaning the terminals in the battery compartment, after removing the batteries, first by rubbing off with a fresh pencil eraser, then by wiping the terminals off with cotton swabs moistened in rubbing alcohol, then letting them dry off for 5+ minutes with the battery compartment door open, then try turning the camera On again.

How long has the battery or batteries in the camera been in-use? If over a year, then you might possibly have a battery/batteries that are getting weak. Rechargeable batteries do get weaker with time, and eventually fail to deliver enough power to start up a device like a digital camera; they then need replacing. The replacement battery needs to be charged up for 6+ hours before its first use, owing to its having been on a shelf for a considerable time.

How old is the camera? in months or years since you bought it.

Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?

Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?

Has it ever been subjected to a humidity higher than 85 % or gotten wet ?

Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?

Customer: replied 1 year ago.
I have 4 batteries and it happens with them all.
Year and a half old; not used all the time.
Do not think it has been dropped.
Has been used it temps above 100°F; Has been used at the beach; has been in high humidity but not in water. No indications of sand in the battery well.
Also have a P900 used with the same batteries and no issues with that; both usually used in the same environment.I will try cleaning the camera battery connections points.

OK, thanks for the requested information.

It sounds as if the use in 100+ degree heat (and humidity) may have caused the problem... and the camera is, regrettably, out of warranty.

I hope cleaning the battery terminals helps.
