Did you also clean the contacts on both the circuit board and LCD with a good quality circuit board cleaner ?. It could also come down to pressure, maybe you need a little more pressure to squish the zebra a little more - just a thought!!
Cheers,

I thought I had it solved when I substituted a strip from a similar vintage 12C I have. The 15C came to life, passed the keyboard test, etc. However, after sitting a bit, the same symptoms came back.
Does anyone else have experience curing issues like this?
One of the problems with the legacy voyager lcd glass design
is the lack of a vertical zebra retainer/stabilizer which makes
(re)assembly a bit of a challenge. Unless the zebras are located
near normal to the pcb before compression, they tend to distort
and potentially buckle to varying extents which will lead to
intermittent or even failed connections. This is aggravated by
the fact the stainless compression frame fingers need to be
sprung apart to seat into the pcb mounting holes. In the process of doing so the display tends to move around and the zebras
along with it.
Eyeball the glass from either extreme side, sighting under the
glass along the zebra length. If the zebra is flexed outward
where it mates with the pcb, you can push it back normal by
carefully pushing under the stainless frame along the length of
the zebra, where and as needed. If it flexes inward that is much
less fun, but you could try to pull it outward into alignment
with a taut music wire or preferably a thin metallic strip
which will have far greater rigidity in the needed direction.
If you need to fish under the display to coax the zebras into
position, you'll also need to navigate around the two alignment
studs which pass through the pcb.

It would be helpful to know what the actual problem is...
