let it run for a couple hours.. it should go away.

After about 30 minutes in, it began popping more consistently and frequently. About two minutes between each pop. What is the process for testing a flyback?

yeah if its still doing it after a couple hours, then it might be the flyback doing something that it shouldnt.

That I have not. I was wary since the loud pops the iMac could make scared me too much. I'm just a little too jumpy for that! :O I'll leave it on in the back of the office and tr…

did you let it sit on for a couple hours?

I gave the CRT, Analogue, and Power Board a good dusting, hooked it all up, and powered it back on. The screen still pops, though not as violently or loudly. This one is a head scr…

If it's just a dusting, that'll make things so much smoother. I disassembled it just in case I need to get to the analogue board. The entire enclosure was caked in heavy amounts of…

i found that if leave them on for a few hours, that noise stops.   seem they do that due to moisture and dust build up. if you can blast them out with the air compressor that woul…

Here is the thread. It's still pending, the work is simple enough to do, but with his move, wthww has been pretty short on personal time and connectivity to make the fixes.

I don't know if they're prone like the early iMacs, but it's definitely an known issue. Probably needs an analog board recap.

So today a friend of mine came in with a big and beige PowerMac. It powers on and works, but the screen and picture tend to pop and go out. Are these models prone to flyback failur…

General DTK question: has anybody looked at operating systems other than Mac OS X on them? Windows 7, 8.1U1 or 10TP would probably do really well on this thing, especially if the P…

I agree with Macdrone. Apple Utility HD will format the drive if it is working. That is a Big if. What kind of noises is the drive making? Anything other a constant high pitched w…

Well you can try Apple HD utility on a system 7 floppy.  But I am gonna jump out on a limb and say the hard drive inside is stuck or dead unless you know it was erased.

Hi, I have a classic two which has to support for hd20 emulation. It has a hard drive in it, which spins up and makes noises, but it does not mount when I boot up the mac. Is there…

In re piracy links: Please don't. especially Mac OS X itself and OS X-era software. All of that stuff is stuff you know is actively being developed, and most of it's still activel…

Your best bet truly is to image the drive that came with it (unless you also got whatever installation media Apple shipped with it) and then put a new drive in to install some othe…

I deffinatley have a copy of that around (i'm not going to post a link here as per the rules though)

Thanks haplain! It's supposed to be build 8F1111. It was once very popular, but like almost every torrent I know, it died many years ago. Back then, I don't think people saw the hi…

I'm fairly confident that I have the correct version of 10.4.3 for Intel on my NAS LaCie... I'll report back.

Unfortunately, 10.4.1 is extremely finicky regarding the supported hardware: the Intel GMA900 and GMA950 chips are effectively the only GPUs supported with graphics acceleration.  …
