Greetings,

I finally got back to being in town and having enough time to do some in
depth troubleshooting. what I have found is that the flat ribbon cable, foil
ribbons, between the control circuit board and the LED display must be the
culprit. When I have the box open and the clock set, then set 8888 I get
Backward E backward C 1 on the left and nothing in the last spot. The flat
ribbon cable is in an inverted U. When I rub across the cable which flexes
it, the unlit segments of the 8888 light up and go off. This cable connects
to the landing spots on the circuit boards with no apparent solder
connections. Almost looks like a spot weld. Do either of you, or others
reading this message know how this connection is made? Can I strip off the
flat ribbon cable and solder fine wires in its place? Any other ideas?

Thanks again for your help!


Don't know specifically for that cable but these are low speed low power
signals so any way you can manage to connect them will be fine. Either
jumper over the defective wires or figure some way to apply pressure or
use conductive glue.
