The process was actually really easy. The new display has a 1-1 pin layout. No additional pull-up or down wires or resistors were required.
I desoldered the ribbon connector from the old display, and resolderded it onto the new display.
On the backlight driver board, I desoldered the Q1 driver transistor and transformer. The supply voltage to the backlight driver board is an odd 7V. I decided to use an 100Ohm resistor in series. At 80mA the drop voltage will be around 4V, leaving 3V for the LED backlight.
I shorted the VCC to a (former) transformer pin, from which the resistor guides the current to the backlight LED.
The contrast was quite a bit of after replacement, but the range in the menu is quite large, so dialing it down from +14 to -20 did the trick.
On the pictures the image looks white on blue, but it actually is white on black. I’m very happy with the result!
Last night I watched the movie ‘Fifth Element’ from Luc Besson again. This movie has a great soundtrack by Eric Serra, espacially the track ‘Little Light of Love’. Watch/listen it here: http://www.youtube.com/watch?v=k5PFsP-Bux4
So we can conclude Peter Gabriel and Thomas Dolby didn’t have any involvement in this track. It is a track produced and performed by Erric Serra himself (credited as R.X.R.A.. which is ‘Eric Serra’ phoneticallt). It seems someone (hunkydorey2) had a bunch of tracks, among which ‘little light of love’ assuming it must be Peter Gabriel´s voice and put it ip for download in the early years of internet. Since then it has gone viral. Anyone who has more insight on this perhaps?
