Hi,
I have a Imac 21.5 inch,
the unit won't boot up just gets to the apple logo and then thats it.
I have had it to a apple authorised repair centre and they say that the logic board has a problem board id. 661-00147
is the 661-00147 board the same as a 820-4668 board?
is the board fitted to other models ? as I have a chance of getting a 27inch unit which has a damage screen/case (same year)
thanks mark.
