Sometimes, meter needle sticks to the post. Set to auto, open lens all the way point at very light and lightly tap body. This may dislodge needle, but it will stick again. Meter string under housing could be broken or unwound. Problem could also be that meter coil is "open", would require meter replacement if so. Lots of new and used parts in stock. An overhaul may seem like a big investment, but you'll end up with a fully functional body with new foam and a six month warranty. John, www.zuiko.com
