[Histonet] Benchmark Problems

We started having a strange problem with our Ventana Benchmark XT.  Out of the blue, our slides stopped staining.  With most antibodies we get no reaction, some that were very strongly positive are now only very lightly staining.  They do appear to counterstain OK.  Following Ventana's recommendations we completely changed out all of our bulk fluids, purged the lines, changed antibodies and DAB kits.  The last shot is some kind of instrument issue that's not triggering an error.  Anyone ever see anything like this?
