I noticed in another thread someone mentioned LED backlighting was available. What is the source/company please? I have both a K5 and K5m.. both with the output mod... i'm considering selling the K5m.. let me see but if anyone is interested let me know.

I'm interested in the LED back light option as well. Is it, possibly, just a matter of hooking up bright LEDs and placing them around the display? Using duct tape, of course, to hold them in place ;) Sent from my iPod

www.backlightsonline.com these are replacement backlights. They replace the original backlight panel behind the lcd

My guess is it's either an LED backlight foil to replace the current EL one with the inverter, or it's a whole new LCD display.
I'm under the impression that this display might fit as a replacement :But haven't looked more into it. It's using an LED backlight and has the same physical dimensions if I remember correctly as I looked into it years ago, but it doesn't mean the controllers are compatible.

Such as eBay no. 190756697843 ? Sounds like googling for Yamaha SY77 display upgrade gives a lot of good options. I've seen many cheaper LCD options compared to the Optrex DMF5005 or Futurlec, but they all use other controllers and a slightly different pinout as well. So far the DMF5005 and Futurlec(unknown model) displays use the same pinout as the original module. The replacement LCD modules might need replacement contrast resistors as I can see, and the LED-backlit LCDs are thicker than the original unit it would seem. That isn't a problem for the K5, but what about the K5m? One other problem for some might be the 20-pin ribbon cable. The original connector is crimped to the cable and soldered on the module, so it's going to be a pain to remove if all you have is a soldering iron + desoldering pump. A 20-pin ribbon cable + a cheap 20-pin male header are quite easy to find online though. -- Antoine Deschênes 2012/11/24 jammie <jammie.emma@blueyonder.co.uk>

i fitted one in my k5m and theres loads of room you have to add washersthe one from rs also fits the 01w t1/2/3/ex and the wavestation sy99 and the k2000and it uses the same chip set as the 5005 displayyou only need to do the contrast mod on the yamahasnever had to do it on the k5m or the sy99they are on back order for the blue they only have black on whiteSent: Saturday, November 24, 2012 7:28 PMSubject: Re: [k5synth] Re: LED BacklightSuch as eBay no. 190756697843 ?
