What now? Replaced 27" iMac video card: backlit works, no image shows
Based on a lot of research, my iMac was suffering from the vertical lines hardware display issue and I found a place on eBay that replaced broken GPUs.
After replacing my video card the screen is still black. I see the backlight come on during boot and I can control the computer, play music via keyboard shortcuts etc, but no images display, no boot apple logo, etc.
I’ve checked the cables like 10 times and rebooted this thing so many times. What else can I try? I’m about to give up on this beautiful machine that still works but seemingly something is out of place. I replaced the vsync cable after a damaged one and that was working okay.
What else can I try to revive this iMac and resolve this pesky display issue?
