Turn the power off and on again message
When i turn on the camera, the lens focusing two or three times open and close, then the message comes "TURN THE POWER OFF AND ON AGAIN" in the display.
The Sony Cybershot DSC-W55 was released in early in the year 2007. It is upgraded with a 7.2 megapixel camera compared to the previous model's 5.1 camera and has 56mb of internal memory.
balaji, this message most commonly appears when the lens does not fully retract or opens.
"Lens won't fully extend ¶
Screen shows Turn off and on again. ¶
Turn off the camera, remove the batteries from the camera and wait a few minutes. Replace the batteries and turn the camera on.
If the lens will still not extend, replace the batteries and turn the camera on.
If the lens will still not extend, check to see if there is any particles in the lens barrel. Blow air in the lens barrel to remove any sand or grit that may be preventing the lens from extending completely." I've had some good result by using a vacuum cleaner to assist the lend to extend and to clean it out. There is also more generic information about that on here. You will find a decent video (not exactly your model, but same problem), on youtube Hope this helps, good luck.
