Contax 167mt

Hi there,

am not sure I have the right category here, so apologies if that's the case. I am seeking some advice regarding my Contax 167mt which I use with the base battery pack (which has the centered tripod mount) the problem iam having is that despite changing the batteries in the "power pack, for want of a better word" and in the camera , without the "pack" attached, the camera is not working and all that happens when I press the shutter release button is the LED display continually flashes. any help would be greatly appreciated.

Thanks
