Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Is the question answered and the problem solved, then?
If not, let me know, and I will advise you specifically about it... Thanks.
So something is seriously wrong then.
The next thing I would try, is a factory settings reset. It will wipe out all White Balance settings and such things among your preferences, but will not erase pictures at all, nor alter the real-time clock and date settings.
Would you like to try that?
Also, about your camera's history:
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?
I'm glad to hear that it has been by and large taken good care of. Keeping it in an insulated leather case (or equivalent for insulation and dryness) is always good, even in a heated environment like a beach.
(How old are the batteries in it, that you have used lately to power it?)
To do a factory settings reset:
go over to the 'wrench' tab with three ticks on it... the right-most tab, really, or next to the right-hand-most tab...
scroll down to the menu choice
CLEAR ALL CAMERA SETTINGS
and press SET
then select OK
and press SET.
The camera will be reset to all default settings (except Language and Date/Time settings, pretty much.)
Let me know how that goes, and whether it helps.
It is called, literally
and is one of three settings, with slightly different phrasing for the other two (because they do slightly different partial clearing of camera settings.)
Where do you no see the choice?
Have you scrolled down in the menu? it's often 'hidden' by being two or three screens down.
