Vintage Synth Repair

i had 6 from him and had no problems

but i think you might be right

as all backlights have now been removed from there site for synths

i reckin he made some for himself and had a few spare

and you must off had the last of them

i also use a guy from china and his displays are the same size and the cables come out at the side and not the middle like the glow safe 

but you have to trim them to fit the 01w

as for backlight4you there terminals also come out the middle and you have to solder wires to then so that you can solder wires to the terminals

but all connections are done out side of the glass

or buy your own sheet if you have plenty todo then make them up your self that way you can put the wires whre you want them

itseasy todo

i just used the glow safe ones as it was already done for me

  Subject: [vintagesynthrepair] LCD BACKLIGHTS WARNING!!!


    

  sorry guys I also forgot to mention that these backlights are not easy to install at all
  although they come with ready made wires protruding, the area where the connection is made is more to the center then the original Korg backlight that has 2 very thin ‘film-type’ wires coming out of the left side.

  although the backlight itseft is thin and easy to push under the LCD, the connection where the wires are soldered isn’t and also worse then this the guy puts silicone adhesive that makes it more thick and if one is not extremely careful could break the LCD glass.

  if you manage to push it in like I luckily did.. you will end up with a non-professional display with a slightly blackened LCD where the connection is made as this is touching/pushing with the glass.

  so I am still looking from other sources that have the wires coming out from the side as in original korg factory ones

  keep your eyes open everyone!

  ----------------------------------------------------------


  my experience with Glowsafe is different:
  out of 2 backlights sent 1 did not glow (so for me it was not safe like they say at all!)

  have been trying to contact them and sent several emails to no avail – no replies!
  however when I contacted them 1st time by email about sales I was answered immediately by a guy named Paul.

  so at this point I’m stuck with a non-glowing backlight... but the Lord works in mysterious ways and so I leave my faith for the righteous to go forward in HIM.

  so also... I do not recommend Glowsafe at all and be careful!!
  this could be not a company at all but just a one man band freak trying to rip out money from decent people trying to make a living.
  he could even be lurking somewhere around here.. so be warned fellas!

  it’s a pity as I have several 01/WFDs coming all needing backlight replacement plus a general refit etc..
  so guess now with whom I will make my order with:

  If any tech on this forum has alternative sources please be kind enough as to mention it here thanks
  after all.. that’s what forums are for, right?

  Cheers and good work and health to you all.

  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

  go onto there web site and

      optrex stop doing those displays becuase they were not rhos compliant

      they have equivelents same spec but use led back lights meaning they are about 7mm thicker some synths its not a problem but others it is

      but becuase yours is ccfl the led backlight versions are about the same size

      where 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 those

      safeglow 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 soldering

      i have fitted them to my sy99 sy85 kurzweil k2000 kawai k5 and k5000

      01w 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 cable

      that gives you another floppy drive power conector and a male power
      connector 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 quicker

      becuase its an insulated product you can just leave it inside the case i taped mine to the side of the case

      they work well and are made for the newer efoils so they connect straight in

    Where I can buy such inverter and backlight foil?

      you can fit a 40x2 vfd in s900 /s950/roland d50/d550/jd800

      yamaha tx16w

      casio cz range 

      and lots of yam synth especially ones with out efoil circuits as the vfd uses neon lettering and does not require a backlight power conection

      also 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?


    Thanks for answers.
