Hello heatman Hi. I have a problem. I have pentax optio which was working fine but one day when I turned it on, it powered up but the screen shows grey. I tried to turned it off and on many times and it turns on and off fine but still the screen is all grey nothing else but grey color on the screen. The flash works and it blinks like it takes picture but still the grey screen. If someone knows what the problem is let meknow. Thank you so much in advance. Now i have read the solutions and it says either the ccd or shutter not working. 1: whats a CCD and or can i fix it or do i just repair it or buy a neew one? Cheers Vesna

You cannot fix this problem. Contact the local dealer or customer service to have it repaired.
For your information -
A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. CCD a major technology for digital imaging.
In a CCD device, the charge is actually transported across the chip and read at one corner of the array.
An analog-to-digital converter turns each pixel's value into a digital value. CCDs use a special manufacturing process to create the ability to transport charge across the chip without distortion.
This process leads to very high-quality sensors in terms of fidelity and light sensitivity. CCD sensors, as mentioned above, create high-quality, low-noise images. CCDs use a process that consumes lots of power. CCD sensors have been mass produced for a longer period of time, so they are more mature. They tend to have higher quality and more pixels.
