I need to buy a new LED driver board for my iMac does it matter if i replace a 602HF driver board with a 604HF driver board
@samuraisammy looks like the part number for the backlight board for the 27” iMac Mid 2010 is/are 661-5576, 612-0075, GDY, GDZ. V267-602HF is the 661-5576 and V267-601HF is the 612-0075. So yes, they should be interchangeable
