they are the perfect fit for the 240x64 lcd
displays they all use an equivelent lcd display size dont need to cut the efoil
as they fit them all
they sell an invertor to fit it to
but e foils all work on the same low amp high
frequency ac voltage 200-400 hz the high the frequency the brighter the display
but also the higher the frequency the quicker burn out
they also work on dc
150v-200vdc but burn out a lot quicker with
this vaultage
the invertors range from 5v to 200-400 ac voltage
hz and 12v to 200-400 hz
it all depends where you are taking the voltage
from
the tx16w uses both on its floppy drive so its easy
for you to choose
also being in japan there is a chinese firm that
does them aswell
but those you will have to cut to size your self
but come in variuos colours
glowsafe efoils are the standard whitish blue
light
i used to cut my own but glowsafe are so cheap that
it safe me the time effert in doing it as its already done for me but they only
do the one colour thats the white blue light
with the manufacture of the vfd it will be exact
same header so all you have to do is remove the ribbon header and fit new ribbon
header
thats what i do with all the 40x2 vfd
displays
noritake itron uk i use but they have a usa factory
and one in japan
noritake japan
for the tx16w its the 40x2 vfd display
pdf for it is added
just solder the same 14 connections no back light
needed and no nasty whining noise from faild efoil
you buy direct from noritake good service fast
delivery and the best display there is you can stand 3 meters away and still
read what on the screen
unlike a lcd become total blank at a few
paces

optrex stop doing those displays becuase they were not rhos compliantthey have equivelents same spec but use led back lights meaning they are about 7mm thicker some synths its not a problem but others it isbut becuase yours is ccfl the led backlight versions are about the same sizewhere are you based as optrex factory is in the usaI'm in Japan, but nowadays shouldn't be problem to order from USA. I tried to find modern substitution but they differs in some spec parameters so I'm not sure if it will work...
just do the back light foils on most of thosesafeglow in uk £7 for the back light cheap as chips and they work great they come with long wires so it does not mater if the terminal are in a different place and as seeing the glue terminals are done at factor and you are soldering just the wires it does not distroy the backlight with solderingi have fitted them to my sy99 sy85 kurzweil k2000 kawai k5 and k500001w t1 and t3ex korg wavestation ex akai s3200 x6That's good, where you got backlight foils? What about their size, color, voltage, frequency, which inverter could be used for it?
im in talks with the manufacturer at the moment for getting them to make a vfd exact same size as the 240x64 and pcb fixing holes as its the most used display and they dont do an equivelent yetThat would be good. Will it be compatible to most synthesizers with 240x64 displays? Will be cable connected, or user has to solder it?
i have the schems for the tx16w ill see if i can find them for you and send you a pdfThat would be very helpful. Try to ask me if you need some Service manual, I have huge collection...
i would say the invertor is gone an easy fix is by a 5v to ac voltage invertor for back lights use the come in a small black plastic case with wire for efoil and wires to connect to a 5v supply just just fit a molex hard drive fitting and get a floppy drive extender cablethat gives you another floppy drive power conector and a male powerconnector for hard drives this is what i used with the fz1 as the invertor on those is dc to dc and they burn out the efoil quickerbecuase its an insulated product you can just leave it inside the case i taped mine to the side of the casethey work well and are made for the newer efoils so they connect straight inWhere I can buy such inverter and backlight foil?casio cz rangeyou can fit a 40x2 vfd in s900 /s950/roland d50/d550/jd800yamaha tx16wand lots of yam synth especially ones with out efoil circuits as the vfd uses neon lettering and does not require a backlight power conectionalso they dont require a angle voltage because they are good fromn any angle unlike the lcd modulesWhich model is it and where I can buy it?
