Dear Community,
I have an iMac Mid 2010 with an i3 processor.
Since a couple of days I haven't been able to boot the device. You can hear the boot sound but unfortunately the screen stays black. I've tried using an external monitor, but still no screen.
I opened the device up and noticed the following diagnostic LEDs:
Does someone have any advice?
Thank you in advance.
Frank.
iMac, macOS Sierra (10.12.2)
See page 26 of this manual http://tim.id.au/laptops/apple/imac/imac_21_mid10.pdf
I still have my training wheels on, but it looks like video card failure.
You may be able to replace it, very, very hard...
a mid 2010 5 series or mid 2011 6 series will fit,

Fun thing is, you can put an i7 processor in at the same time.

I would use a i5-750S, or i7-860S / 870S processor...
Max memory increases from 16 to 32 gigs....
