I have same problem in my DSC-F717 camera which I bought 2 and 1/2 yrs ago in US. Now I am in India and a faculty member of Dept. of Biotechnolgy, University of Calcutta.Last three months I didn't use my camera. when I turned last weak-end sept 03, 2005, I found that some redish lines then totally dark on LCD. I took the to service centre of Sony, they told me that CCD had gone. I will have to pay US $400 to replace total unit. I am very much surprised and shocked. It was US $1000.00 when I bought (so expensive!!) and within couple of years, it is gone. I would like to ask sony what is the quality control they are mainting in high price digital camera? I am requesting sony to take steps to solve this problem and help us.
