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 usa
I'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 x6
That'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 yet
That 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 pdf
That 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 in
Where 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 modules
Which model is it and where I can buy it?
