The shutter fires correctly at all speeds except 'O'.<br /><br />When the shutter is released at 'O' setting, the shutter stops midway because the bottom roller becomes too fat and the wound cloth rubs against the body casing. A slight push on the roller and the shutter is wound up.<br /><br />As you can see, the spring has 'juice' and the cloth seems tightly wound on the roller.<br />This problem appeared suddenly : it was working perfectly till now.<br /><br />Help welcome...
