I have a meter with intermittent display segments.

Maker and model number?

I've cleaned the board and (carefully) the LCD glass contacts.
Not much help.
Neither did cleaning the zebra strip.
Is there anything I can do to the zebra strip to help?
I've thought about shaving down the plastic to get more compression
on the strip...but there's no coming back from that.

If you look carefully at the strip, you'll see that the connecting PCB
traces has created an indentation in the strip. If you rotate the
strip to a different side, the indentations will not make contact.
There are 8 possible ways to reinstall the strip, 7 of which won't
work. The trick will be to find the original orientation. Shaving
the existing connector won't help because it will reduce the
connection pressure.

However, I don't think you'll have much luck getting it back in
position. Find a replacement strip and it should work, assuming
nothing else is blown/broken/trashed. Search for "elastomeric
connector strip".

"There are 8 possible ways to reinstall the strip, 7 of which won't

The point of zebras is they have very great latitude for mis-positioning,
I've found replacing back-in in another 1 of 8 orientations often works,
admittedly I flip in a vertical sense and flip longitudinally ,not
necessarily solved the problem for very long though.
Assuming the zebra is nominally held in a plastic well, then "shaving down
the plastic " does work , and is a more long term solution. I mark and use a
file to remove about 1/3mm all round, just freehand, again zebra latitude
comes to the fore again - I wonder who thought up such a clever solution.
