That's an interesting thought. It's almost certainly an IC, though I don't know the details of the panel (though it looks like it's off-the-shelf, not RDI-custom). I suppose I could start with what's in the cooling airflow zone. My worry is if I found the marginal part(s) I'm not sure how I could easily fix it (with my luck it won't be a discrete part). -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- A penny saved is stupid. ---------------------------------------------------
