Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.
At longer focal lengths, camera shake becomes an issue. The icon may signify that you changed to a longer focal length... make sure you have not got the camera Zoomed in too tightly.
Or, that your holding of the camera is unusually unsteady? perhaps.
Have you selected Auto EXR Mode? if so, then 4 pics will be taken and the best of those (the least blurred by shaking) will be stored.
It may also mean that you need to try using a tripod. Or possibly that your flash is disabled?
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 old is the camera? in months or years since you bought it.
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.
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?
