I purchased a used 1998 Crown CE1000 for our once a month, all volunteer, benefit concert series.   It worked great the first time we used it.  A month later at the next show, we couldnít get it to work (no output on either side).  The fault light is on for both channels.
I donít know if it is a coincidence so I will mention this:
We have 4 main speakers (2 on each side of the stage).  Prior to the second show we have always put all 4 speakers on our QSC amp and we fed 2 monitors using the crown with 2 separate inputs.  For the second show we decided to put the outer 2 on the QSC and inner 2 speakers on the Crown.  We went from one channel on the snake to the crown using a balanced splitter, (1)1/4Ē to (2)XLRs.  My sound guy assures me that it did not cause the problem, but I am throwing it out there because it was the only thing different from the show before.  
I have the schematic (by email from Crown).   I work at an Electrical Engineering firm.  There is a person or two familiar with schematics here.  Is there a shortcut for checking each of the 5 items that can cause the fault light to come on?  Of course I would love to check voltages on the top of the board and not have to remove it to check the bottom of the board.  Every dollar that I can save is a dollar that can go to one of our 3 charities for the year.
Sorry for the long post.  I am sure I left something out and should have left some other things out.   wink.gif   Robert
