This one is a doozie...
I wanted to see if I could run a very early version of Linux on this Mac, so I got an installation disk for Linux. I tried to boot from the disk, to my surprise nothing was showing up on the TV that the Power Mac was connected to. No grey screen, no boot menu, nothing, even though everything else appeared to be operating fine inside the Power Mac.
Here’s what the diagnostic LEDs are showing inside the Power Mac.
Did I brick my machine by trying to boot from this installation disk? Did my graphics Card die?
Things I I have ruled out:
- The VGA cable is fine, I tested it with my Mac mini and it worked.
TL;DR: Screen is black, but startup chime is present, fan is running, and 2 LEDs are lit after trying to boot from a linux installation disk.
Is this the CUDA button I am looking for? I cannot distinguish between them. Tried pushing both of them, the one on the right made the Mac power on and off, the other one on the left made the Mac do the boot chime and made the optical drive rev up. Still no dice when it comes to the display, there’s nothing being shown. No flashing folder, no grey screen, nothing.
I removed the PRAM battery for 30+ min and that didn’t help either.
CUDA button was a no-go. I left the PRAM battery out for a full day now, thats a no-go too. Boots up, fans are running, optical drive operates, but no video. One thing I have noticed is before this incident happened, on boot up ALL of the LED’s on the logic board either stayed lit or blinked after booting up. After the linux incident only 2 of the 4 LED’s stay lit after the initial boot up. Could this be a sign?
I am leaning towards a graphics card issue. I just don’t want to be pouring money into unnecessary places.
I am afraid that this machine is a brick now. I'll try a new GFX card as a last resort.
A new Graphics Card didn’t work. This machine is officially a brick.
