- I don't know, but they're probably crappy
It'll be a necessary first step to test and label all pinouts from a running 24" Machine to determine which wires are which.I would caution about determining the iMac PSU pinout- it is confusing. All the wires are black!
I used an external PSU (12V 5A CHANZON) for this mod. For a 20 inch, this is a much better solution than an internal PSU. For a 24 inch, however, I believe the screen required 24V rather than the 12V the 20 inch required- but I could be wrong.I think the 20-inch psu has some difference ... did you use that ??
The brightness how do you manage it ??
I’ve modified it to work with a third party PSU. I used the EQ Store kit for the display and connected the controller board, PSU, and inverter so they make kind of a triangle of wires. Basically, you plug a standard ATX power supply cable to the PSU, connect the 12v to controller board, 24v to inverter, and a green and white wire from inverted to controller board for what I would assume is brightness. And LVDS from controller board to Display.I'm in the process of upgrading my 2006 A1200 24" iMac due to graphics issues and the need for a faster machine.
I love the design and there's no way I want to get rid of this.
I accidentally purchased the 20" kit for the eQ Store and I've tested it to work fine on some spare 20" iMac parts I had, including having it all run off the original iMac PSU.
I'm trying to do all the research before I diassemble the iMac as although I've got a fair bit of experience working with the white generation, my 24" is in great condition and I don't want to mess something simple up.
Unless it dies, I am using the original PSU to power the controller and display/backlight as it seems wasteful to buy a new one.
The unknown for me is the inverter on the 24" display being built in. I've read in this thread of some 'control' wires and I'm not sure where these would go.
Has anyone successfully modified the display to work? I would also REALLY like to have backlight brightness adjustment as I find the stock lowest brightness far too bright.
