Re: Re: LED Backlight

i fitted one in my k5m and theres loads of room you have to add washers

the one from rs also fits the 01w t1/2/3/ex and the wavestation sy99 and the k2000

and it uses the same chip set as the 5005 display

you only need to do the contrast mod on the yamahas

never had to do it on the k5m or the sy99

they are on back order for the blue they only have black on white

  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.
