horizontal lines in my photos

[great34]

Hi everybody,

My Minolta Z3 took great pictures that day, but later, I tried something, and that's what I got.... Like a blind effect, horizontal lines. Click the photo for a better view.



I tried switching memory card, removed the batteries, took away my filters...

Also. above like 1/200, there's way too much light. The camera is just a few weeks old...

Any Idea of what could be wrong ?


Thanks a lot,

Mike
