when opening a late imac 2012 27” EMC 2546 there is a display data and power cable. while it’s quite easy to discern what way “up” the display LVDS cable should go, is there a trick to determine the correct orientation for the power cable for the display? (in case it gets flipped around) does any one know pinout for the power plug for the display? ( i believe it is Screen Panel LM270WQ1(SD)(F1))
if a cable requires a specific orientation it is keyed somehow so that it won’t go together any other way without significant force. AC Power cables have 2 or 3 pins. You can’t reverse a 3 pin cable. most 2 pin cables are reversible, but there are some with a key. If it is a DC cable is will also have a key if necessary. No tricks involved, just don’t apply undue force.
