The film advance is on "wind-lock" because the shutter is already cocked. If after cleaning the battery contacts and installing a fresh new battery the shutter still refuses to release, then the most likely issue (very common with AX-1 and AX-3 models) is a dried out elctrolytic capacitor as mounted under the front edge of the double-sided pcb under the baseplate. It is a blue polarised cylindrical 6.3 volt electrolytic of 4 7 microfarads. Electrolytics should never have been used because of their l known propensiity to dry out - and indeed later models of the AX-3 used a Tantalum. Because the legs of the capacitor solder through the pcb and make circuit to both the upper and lower tracks, you have to be adept with a fine-point soldering iron. Remove the two obvious screws which secure the pcb and allow it to hinge upwards by the half dozen fine wires at its rear. You will then be able to access the capacitor culprit. Remember that the capacitor (and its replacement Tantalum) are polarised. Ensure that the negative leg goes to the forward edge of the pcb. Voltage rating of the Tantalum can be 9 volts if you cannot obtain a 6.3 v item. Since Tanalums are significantly smaller than electrolytics, the 9v version will still fit comforatably. |
