Good evening. I know that this post is now rather old, but I am hoping that someone can help me. I have the same problem as the O.P. regarding the shutter and mirror not returning to their correct position, but with my EC TL. As it is most likely the timer that is at fault I was wondering if some kind person could make me the replacement IC that is shown in the replies. I do not have the electrical knowledge to make it myself, but I do have the skills to solder the wires from the body correctly to the new timer. I am in the U.K. and would of course pay for the work and shipping costs. Please contact me if you can help. Thank you, Chris.
