I've done a lot of reading on the CZ's in the past.
I discovered the difference in the character sets of display when I upgraded the display
in my CZ-5000 (black on yellow). All of the special characters related to the notation are something other than
what is written in the CZ. After I saw this I tried a few other brands
of display, which I forget the names of now. all were the same or similar to those pictured
below. This does not affect the CZ101, 1000, or 3000. Does make using the sequencer
Cross fertilizing is certainly possible as the display from a FZ1 appears to be from a
graphing FX series from 1987, FX-7000 calculator IIRC ???
the display doesn't fail as frequently as the backlit does. however not being careful
with the display assembly will cause the display to fail due to the joints of the cables
on the driver board and the rear of the screen
The original back-light in the FZ is held in with a rather strong double sided tape.
thats where the issue arises from others around the world who say they've
damaged the screen from changing the EL foil.
space behind the screen itself is a tad over 1mm so there is not much room to play with.
The recess in the rear half the the LCD housing which give that space.
I wouldn't like to remove the foil from the back of the LCD as that
will more than likely take the ribbons cables with it as the foil backing
is over the ribbons. it looks to me as if a previous owner has explored
that avenue, as one of the corners looks like it was peeled back a tad.
I would really love to see my FZ running again, I really like the sound of the old
melotrons in it.
Some picture below to help illustrate the issues. first two CZ-5000 screen.
last two the FZ-1 out of the synth.
1. the top right of the screen would normally show A crochet symbol followed by and equals sign then the tempo.
2. this image should show a crochet and a semibreve
3. FZ-1 screen cables and board
4. FZ-1 screen cables and board
Edit: I believe I had the data sheet for CZ-5000 screen somewhere, now i am curios to compare
that to the CZ 1000 .....
