Does the yellow-goop on the circuit board look like blown capacitors to you experienced EE people?  The price was "free" so couldn't argue with it.  It powers on and fans spin, but the LCD screen shows nothing, and not surprised considering this looks like the main control board.  Before I call Sartorious wanted to get some feedback.  Nothing else looks out of place on the rest of the boards and connections or fuses.  Thanks.

The yellow stuff could also be some sort of adhesive. But maybe still worth to check the capacitance, if you didn't find a obvious fault(like blown fuses or maybe a switch that isn't closed)

Thanks.  I poked it and it did seem to be adhesive.  Chances of finding whats wrong with it low now as they don't service it but will sell spare parts.  Maybe it's just a bad screen.
