The images look ok in GIR_Editor:
They are the same size/resolution as the images in my AU1690 so your two EU1690s should have the same as well. You could substitute the 4 x PNG's and try reflashing the logo bin. Do you need help with that? If flashing the logo bin containing 'known good' images doesn't work then the problem is elsewhere and the device may need to be cured with [Only registered and activated users can see links. ].
EDIT: Not only are the images the same, i've found that the logo bins are the same. So just flash your 1690 logo to the 1695, or even easier for you, i'll upload the logo bin and attach it in Post #1 here.
