So I got an XD7 recently and it only works in metered manual mode. When in AE/Shutter Priority- the LEDs will slowly ramp up from the proper shutter speed/aperture to the overexposure indicator
XD-7 was the Europe version of the XD-11. Does that mean you are in Europe?
In the US, I have seen John Titterington's name associated favorably with Minolta repairs. I can't find his website but I believe he may be an active seller on ebay name Titterington.
I have an XD11. I sent mine to Garryscamera.com. His service an turnaround were quick. Took about a week and I received it right before I needed it for a funeral.
