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.
Question 1:
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?).
Qustion 2:
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?
Question 3:
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!
