Hi Michael, Sorry to hear that... I just looked up a Favourite I had saved with a step by step to reseat the flat multicable leading from the Card Reader but it seems to have been removed from the 'net :<(
It may be worth Googling "D70 repair" and see what pops up?
Hope you can get the D70 going again!
