Acuson Aspen Replacement Original Monitor

problem with the original monitor of acuson aspen us, and its very difficult to find a replacement, so I need the VGA connector diagram (17 pin: 1 line 9 pin and 2nd line 8 pin) to convert for DB15 pin (computer monitor 3 lines of 5 pin each). Of course I will keep the softkeys and mount it separately. By the way, the original monitor has lost the contrast, whith the knob up to the max, the image is still pale.
