Inverter Board from iMac 27 mid 2010 to iMac 27 mid 2011

Hi. I have an INverter board from an Imac 27 mid 2010 EMC2390, the question is if I can replace the inverter on an iMac mid 2011 with this one. It is compatible? At first sight it looks similar. Thank you

@macpatagon posts some good pictures of both your driver boards with your question. Let's see what you got going on here Ajout d'images à une question existante


@oldturkey03 - Please re-read my posting. There are two versions! The lower NITS display is the four conductor version.

Technically its a LED driver board not an inverter. Inverters are used with CCFL backlights.

The 2011 iMac came with either a four pin version iMac 27" LED Backlight Board V1 (4-Pin) or an eight pin unit iMac 27" LED Backlight Board V2 (8-Pin). To complicate things a bit both use the same P/N 923-0047. You’ll need to inspect what you have before you order the part.

As far as using a 2010 board I wouldn’t.

Hi dan, thank you to clarify.

the lcd board that I have came from a non working iMac 27 mid 2010.

this board has four pin just like the one in the iMac 2011.

it will be Work in that iMac? Is there any risk to test?

thank you to take your time


It's not the same part, see for your self a very different P/N 661-5576 iMac 27" LED Backlight Board

Again, I wouldn't chance it.
