OK.. One thing I have learnt from years of 'remote fault finding' is the
qurstion that Iforget to ask is the one that gives the real clue to what
is going on :-)
I just
got done trying this. No dice, with the membrane disconnected 3
of the LEDs light up constantly and that's it (no beeps or anything
You did
remove the metal clips from the PCB and not just pull out the
membran tails I trust. If you do the latter, said clips short all the
pads togther and cause all sorts of problems. else).
With the membrane connected I get 4 LEDs and a few very short
(shorter than I recall under normal circumstances) beeps. So perhaps
the membrane isn't to blame in this case.
Thsi, AFAIK, makes no sense. A
correctly working membrane assembly is
open-circuit between all conenctions. So the cotnroller PCB can't tell
whether it's connected or not.
