Oh my goodness, don't disassemble and don't go banging your A95's up for this problem. Sorry I missed this post when you first submitted it.

Call the 800 number. Originally the A85 wasn't included in the repair recall, but they added it in 2006. I had the same problem. Hope this helps!

Sencor is bad,I have repair this before.

Yup, it is a common problem. The shutter is jammed. I bet outside pictures are really overexposed. The horizontal lines are caused by the electronic noise created by the shutter solenoid trying to move the shutter. If the cameraq is no longer under warranty- Sometimes, you can free up the shutter by banging the camera in a hard surface like a desk or table. (Do this carefully, don't get carried away) If this doesn't work, you will need to replace the whole lens unit. this is best if the warranty is still good.
