hello
I have a problem with a late 2012 iMac (21.5-inch slim)
model number A1418
EMC 2544
Mother board 820-3302-A
It does not turn on
So I filed the screen
There are 4 diagnostic LEDs
test 1
with power supply cable connected
Black
Black
Black
green
test 2
If I press the button, there are just
Black
green
Black
green
nothing happens on the other
no ventilation which turns
no beeps nothing
however these LED corresponds with this model?
Usually: power unit + motherboard + video card + screen
The I find bizarre as it skips the second and there's only 1 and 3 lit.
thank you for your help, failure arrival alone
