Dealing with autofluorescence

I'm having a bit of a problem that I'm not sure how to deal with. If I run freshly isolated unstained mouse spleen cells through our FACScan, the cells autofluoresce equally into FL1 and FL2, to about 10^1.5 or so. In other words, there seems to be a perfect diagonal of a few cells that autoflouresce (the majority are below 10^1). Gating on any population does not affect this pattern. I prep the insturment using Calibrite beads, but have not tried adjusting any of the settings to fix this. I've harvested spleens in serum-free DMEM (with phenol red), serum-free HBSS (with phenol red) or PBS and have washed 2x in 0.5%BSA-PBS, all with similar results. Are there any suggestions as to how I can get this under control?
