Hi, I have a few questions regarding this topic.
I am going to try and “rescue” the LCD display from my 24-inch white iMac A1200 after the motherboard failed.
The LCD display is from LG.PHILIPS with model Nr.: LM240WU2 (SL)(A1). Inverter board already part of screen.
I have ordered a controller board from China specifically for this purpose, with HDMI, DVI-D and VGA connections, which hopefully will allow me to use it as an external display. I think it is the same as the M.NT68676.2 you show in the post above. I presume they will supply me with all the necessary connectors for the screen - they said they would after I gave them all the information.
I would like to use my existing iMac power supply, and my understanding is to take the +12Vwires coming from pins 6 or 7 (or both?) of its connector, however what is the ground wire that I should take? Is this one of the “0V” wires from pin 1 or 5 (or both?).
The inverter board already on the display should reveive +24V, however I was told by the person in China who is providing the controller to simply connect a +12V DC power supply (3 or 4 Amps) to the controller. Will the 3rd party controller board convert to 24V for subsequent delivery of power to the inverter on the screen?
The 12V output from the iMac power sullpy is more than 4A i think (more like 20A if i remember well). Does this matter?
Thanks a lot for any feedback!
