<p>I have a Nikon N90s, and I've taken it out to use it, it's been stored for a couple of years in climate controlled conditions, and I've noticed that the meter seems to work fine, but I'm not getting any aperture readout on the top display or in the viewfinder, only lines. I've tried several different lenses, no change. I use older manual lenses, I've never used af lenses on it. I just put in new, topped up eneloop batteries in it. I've tried with and without the MB-10, no change. I do have an MF-25 data back on it, which seems to work fine. I think I could use the camera as is fine, I'm used to checking my aperture setting on my lenses visually anyway. Anyone have any tricks to 'wake up' the aperture readout?</p>
