I have recently had problems downloading video from my MV750i (never a problem before). My PC no longer recognises that the camera is attached. I have unsuccessfully tried a number of working Firewire cables so it seems the DV terminal pins in the camera may be damaged. Does anyone know if the part can be replaced and where I can get a service manual (preferably free) to see how it is done. I have tried a number of sites but they are looking for fees. I am currently unemployed so even a small fee is high to me.
