iMac doesnt start after changing graphic card
I’ve changed the graphic card on my iMac (late 2009) and now i can’t start my mac anymore.
I’ve already changed the graphic card once and the imac worked perfectly after that.
But now, first when i started, I heard the interior start, but no chime, no start/boot. Then i removed it and put it back in and now there is also no noise anymore and no booting.
The card is the right model and I dont think I’ve connected the cables the wrong way.
I’ve also checked the power cable, unplugged, re-plugged after 10 seconds etc.
Unfortunately I can’t see the diagnostic lights, because of the black tape covering it and I can’t remove it correctly without maybe damaging the motherboard.
Any ideas what the problem could be?
Thanks in advance,
Ok, thanks, I’ve removed the tape (how difficult can one make it?)
So LED 1 is on, when i hit the power button, the light goes off and no light is on.
Does this indicate the power supply is damaged?
Is this a good question?
