Hello all,
I recently purchased an official Apple GeForce4 Ti 4600 from an eBay seller who claimed the card worked, but when I received the card it wouldn't work in my machine. The seller graciously refunded the money for my purchase without requiring me to return the card, so now I am looking to diagnose it in the off-chance it can be fixed.
I have a 2003 PowerMac G4 MDD with 2x 1.25 GHz CPU, 2 GB RAM, ATI Radeon 9000 Pro (which works perfectly in OS 9.2.2 and OS 10.4.11). There are no cards in any of the PCI slots. Swapping the GF4 Ti 4600 in place of the Radeon 9000 Pro results in a black display throughout the entire boot process. I can hear the boot chime, but the display remains black; I have no idea if the machine is fully booting and reaching the desktop, or stopping at some point in the boot process.
It appears the card is attempting to send a signal to the display, because it's not simply blank but rather black. The power light on my display is amber when no signal is being received, and white when one is being received. When the G4 is part way through booting, the power light switches from amber to white. It's an HDMI display, and I'm using a DVI-to-HDMI adapter to connect to the display. At one point, the display stayed mostly black but showed a somewhat-flickery small green bar through middle.
I have removed and re-seated the card several times with the same result. Upon swapping the Radeon 9000 Pro back in, everything resumes working perfectly.
Anyone have any idea if this card can be saved, and/or how I should go about diagnosing it further?
