But when I turn it on I still get the lighted display with no words or anything.  And I hear a click a second or two after I turn it on. . .like a relay.  I've priced the three biggest chips but it's to much for me to invest for now.  The only suggestion I didn't do was to lift the display up to resolder the chip holder that's under it. I'm afraid of breaking the display. Nice looking rig.  Sure would like to use it someday.  If some of you will recall, I picked this up with the front board and control board complete.  I carefully (or so I thought) retraced every step in the manual and am up to phase 1 of the testing and calibration.  I made sure every piece was installed correctly (as best as I could being a rookie).  I found a couple of things but it was usually just pieces not seated in good, which I fixed.

As Bob it's probably pin #1 on U1.
I had the same problem because I had a cold solder joint on pin#1 of the 
socket.
I fixed mine by using a needle point soldering tip that I purchased with 
my Hakko 936. I made sure there was NO solder on the tip, boosted the 
temp to about 800F, and stuck the needle point in the corresponding 
socket for a 2 count, no longer.

This only works if your sure you got some solder on it the first time.
