Very Bright Outdoor Photos with lines

Hi!
It sounds like that the shutter cable inside lens is partially broken. It moves with the lens while it zooms, so it could loose contact while stretched - when you have zoomed the lens. Z750 and Z850 have this problem with shutter cable - it breaks. The white horizontal lines are because shutter doesn't work. I'm afraid the cable will brake soon and pictures will be too bright with white horizontal lines even at normal zoom. It is considered a hard repair - the shutter part or whole lens unit has to be changed. You can contact your local Casio service center and ask the price, but it will probably be very high. I work in a Casio service center and new lens for this camera costs about 250$. It's not a good idea to put on used lens or shutter, as it will brake again sometime - it's just a matter of time. I suggest you get another camera.

Hope this helps!

don't work shutter, repair lens unit.

If the photo shoot out show white , the obscure (quality variation), and even horizontal line ( white lines), and so on over-exposure cases, even if the use of anti-tremor, set to default values are invalid, because the camera shutter fault.

Can't repair by yourself.
It's need repair camera machine shutter.

It is the shutter (or at least it was for me) I found a simple test here: http://www.mydc.com.tw/repair/knowledge_en/casio-exilim-ex-s600-overexposure-t17.html
I repaired it myself, but it took me a whole afternoon and lots of patience.
The hard part is taking the camera apart, once I got to the shutter I just activated it manually so to dislodge any pieces that might have gotten jammed, then placed it back together again and it worked! :).
It's really hard to take apart, it's like a puzzle sometimes, to find which screws are keeping it together. I also had a bit of hard time when it came to put the zoom back together again.
But I guess it beats throwing the camera away.
I'm still puzzled on how the CCD works so that an overexposure would make horizontal overexposed lines, but everything points to that. Fixed shutter, lines be gone.

buy a new camera!

It appears this problem is due a failing CCD device in many brand cameras. All the manufactures use the same source(s). I have not persued Casio as yet, but other companies are offering a recall to replace the CCD for free. I plan to use this approach with Casio. Search the web for "failing CCD in digital camera", it describes exactly what we are observing.

I just took mine to casio and they repaired it for free even though warranty was up. I would contact them. 

Same problem with mine!  Fine Any suggestions?
