Ok, I got the contrast working now, I can se the bars.. But to get the volts down to 4,2 on my pin 15, I needed a 560K resistor... And when I got that volt it didnt light up.
So I think my backlight must have been broken.
Contrast working is good news. The lcd may be working after all. The 560K is way too big. You will need no more than 560 ohms.
