How can I repair the ribbon cable on an OM-10Quartz databack?
1) Remove Bottom Cover. Four screws. 2) Within the camera body, near the battery compartment, the ribbon cable is soldered to two wires, one is ground the other I think is the x-sync contact from the flash circuit. Determine which wire is ground, this should be obvious from where the wires lead to. Looking at the flex circuit cable that runs to the back, trace the ground to the circuit track. You should be able to work out which of the two copper conductors on the QD back is connected to which wire on the camera body. Write this down. For example: WIRE SIGNAL COPPER TRACK ———————————- Blue Ground Top Trace White Sync Bottom Trace whist looking at back from above. 3) Unsolder this connection and remove the broken stub of flex board. Keep this bit for practising on. 4) Solder the replacement cable to the wires in the camera body. Cover the soldered connections using heat shrink insulation. 5) Feed the new cable through the hole in the body that leads to the hinge (a
