After assembling 10 of the LE, I had 2 of them with a 7 segment display that stayed blank, dig2.
After checking all solder joints for shorts and opens, I started comparing the defective boards against a good board.
What I found
SAA1064 pins
good board bad board
pin 2 3.1 V 2.5 V
pin 11 1.3 V 2.5 V
pin 14 2.0 V 0.2 V
Black meter lead is on pin 12.
After rechecking for shorts, I removed the 2700pf cap beside the SSA1064 chip. Finding the ceramic material it is maid of, was insulating it from the board. Soldered it back in, and presto the display is now working. The second LE, the same cap is bad. A 14 cent part at mouser. I will get it with my next Mouser order.
