iM 4,1-14,4 2011 iMac Graphics Card Upgrade

Just for verification:

1. Are you sure that you have got the correct LVDS vBIOS from Ausdauersportler?

2. Are you testing the 21.5in LCD panel with eDP input on an early iMac 2009 with LVDS output?

It's a 24" model so it has LVDS right?
I used M5100-EnableGop91-LVDS.rom

If you've tried every thing, The GPU is faulty. For a maybe temporary fix, you can reflow the gpu using an oven at 190°C (375°F) for 10 - 12 minutes.. Good luck tho

I've tried that already indeed. Was of no use sadly.
