Electrical – Powering a 6-Pin DAC-08B035 LCD Inverter

displayinverterlcdpinoutpower

i have an old LCD Panel(N141X6 -L01) from a Fujitsu Siemens laptop and an inverter(DAC-08B035) for it. Before connecting the whole thing to a raspberry pi(and buying the necessary controller board), I want to test the inverter(and the backlight of the display). The inverter has a 6-Pin connector with

  • white
  • grey
  • dark blue
  • blue
  • green
  • yellow

cables. I tried to figure them out myself, but I didnt find any documentation for this board nor anything useful. The white and the grey ones are doubled and there is a fuse(transparent thing with a thin copper wire in it) attached to them. They also have the widest road on the PCB. The dark blue one is going backwards under the connector and coming out there. The blue one goes up and the green and the yellow ones seem to be doubled, too. front back
I will be happy to hear your thoughts! Thanks!

Yes that is a Fuse (labeled F1 on the back). And based on the connections, White + Grey are VCC (Likely 12V, but it's can vary, its not voltage specific). Green + Yellow are Gnd. Use a multimeter to confirm, as they will be in continuity with the ground pad around the screw hole.

That leaves Purple and Blue as either Enable or PWM. Which is which, and if they are active low or active high is questionable.

Based on the OZ Micro OZ960S Intelligent CCFL Inverter Controller, you can trace them out easily. Pin 3 is Enable (3.3V on/off signal) and Pin 14 is DIM (3V Analog/PWM?)

FYI: You could simply replace the inverter with one that is documented. A LCD inverter isn't anything special, just a high voltage transformer. Any CCFL inverter or even a neon inverter would work.
