I recently got a Power Mac G4 (Digital Audio)

And when I connected it to a monitor and powered it up, vertical red lines showed up on the monitor, no weird noises, it does seem to boot up correctly by the sound of it.. The pc itself is in great outer condition and seems to be looking great from the inside.. what would you recommend doing?

Have I missed a screw or something or has the coolant done more damage than I first thought?

Could it be that coolant has corroded the socket pins together?

My Cube’s Firewire bus burned out last year after I plugged in an Acer Firewire DVD drive. Now the ports convey neither data or charge.
Looking at the ports, they look distinct from the rest of the I/O, and I’ve seen sale listings for discreet Firewire modules for other Power Mac G4s on eBay.
My Cube still runs fine otherwise, and I can easily add new files simply by removing the SSD and plugging it into a different computer, but the dead Firewire ports make it much less practical.
Can you repair or replace the Firewire bus in a G4 Cube?

I am new to posting questions here and am sorry if this is the wrong place.

Here’s an Image of the Chipset I found Online.

I acquired a PowerMac G5 with a bad power supply. I just replaced it with a working one from eBay, however when I plug the power cord into the back of the machine I hear a clicking noise and a white light over the power button flashes for a quick second. When I press the power button nothing happens. The clicking noise also occurs when I detatch the power cord from the machine. It is a PowerMac 2 Ghz dual processor 7,3. Any ideas on what to do? A video is linked here to show what’s going on.

Thank you

Was this option only there for RAID? If so, did the controller card somehow provide another power connector? I’ve looked everywhere and I can’t seem to find it.

I took it to shop- they told me it was in working order. They took parts from an older non working tower and swapped them (basically swapped video cards and ram). It worked for a day or 2 then no more. Then I took it to my brother (the shop obviously didnt know what they were talking about) and my brother said it booted up fine for him. He though I was crazy, EO. I went over to his house a month later to swap parts or figure it out on my own and he booted it up first hoping to show me it worked, and it did not boot. So we swapped power supplies. I did not test the PS when we had it out unfortunately.

QUESTIONS:

Is making the fans spin when testing a power supply really a concrete test? I tested the one we removed after I got it home. Fans spun fine on 14 & 23.

Any ideas on what this might be other than power supply? Do you think I can test PS when it is in the tower? I don’t think I can get all plugs unhooked without removing the processor.

I always get the click; the light (near the power button) sometimes comes on but not always. I have not tried the hair dryer trick yet.

Any ideas are welcome! I am at my wits end, they either work or are parted (which is better than garbage) but for some stupid reason I like this model-I know I’m not alone.

Now I’m just thinking that perhaps I could make use of the old DVD-R/W that’s lying around collecting dust and replace the original CD-Rom… would it fit? Would it work? Anybody out there has suggestions? Thanks… /cer

Thanks,regards.

PROBLEM: Reconnected the Mac and pressed the “ON” button which glowed for about 1 second and went out. The Mac did not turn on.

SOLUTION, PLEASE:
