So, tonight ended in tears. My replacement Nichicon capacitors arrived two days early, and I got to recapping the power supply board. It was a long, frustrating process, but eventually I got it done. So, I went to putting the monitor back together, but first I wanted to dump out this black dirt...

Never mind - not long after I made this post, my DVD drive bit the dust and would cause the iMac to freeze every time I plugged it in! I think I will invest in another DVD drive, but first I have some other things I want to try out first, like starting up off an external hard drive.

You're right! I already have a Newer branded SCSI MicroDock for my PowerBook Duo, but it has an HDI-30 port. This lead me to assume that other SCSI docks I would find for the Duo would also be HDI-30, but I guess I was wrong. Thank you very much for telling me this!

I recently decided to try out my iMac G3 again that I got a year ago at the VCF East, since I haven't used it for a while, and it's just been sitting on my bench. I do remember that when I used it a while back, I was able to boot off my external DVD drive to install Mac OS 10.3 from CD. This is...

Thankfully, my SE FDHD that has a CR-44 (not sure about the M, might be slightly different) power supply was already apart, since I think that I'm going to do a recap soon. I pulled out the power supply, and checked my voltages without the motherboard or analog board connected. From black to...

Good luck, and be safe. Just remember that if you can't trace down the problem yourself, there are many, many others out there that can certainly help. Or, there are modern replacement PSUs with modern components that might be worth looking at. Please, do let me know how things turn out!

I'm not totally sure, but maybe try checking for shorts or corrosion damage. The voltage between the 12 volt rail and the 5 volt rail would be 7 volts, which may be related to the problem you're having.

Before you recapped, was the power supply outputting the correct voltages?

The faint scanning line is practically impossible to see in a video, due to the refresh rate of these CRTs. I don't have quick access to a video camera with an adjustable frame rate, so a picture is the best I can do. You can barely see it, but it is on the axis the arrows are pointing to...

I have a few PowerBooks: a 140 (that doesn't work), a 520 with a PowerPC upgrade, and a Duo 230. I accidentally damaged the ribbon cable for the floppy drive (which I will soon replace) while unjamming and lubricating the floppy drive in the 520, and the PowerBook Duo doesn't have a floppy...

I looked up the chip, and found some potential replacements (only one digit missing) which I'll link to here, and another one that is listed as "high quality second hand" here. Unfortunately, according to this forum, this chip is likely responsible for the floppy drive. Maybe try looking for...

Love your YT channel!

I have an SE FDHD with a similar problem to what is being described in this thread, except that the shake is a more intense, larger twitch. Also, there seems to be a faint line constantly scanning down the screen. Should I look into this transistor?

Also at the VCF East (See what else I got!) I picked up a Macintosh SE FDHD for quite a good price. I could see that there was something in the expansion slot: a bracket with DB-15 port. Taking the machine apart further (mainly for lubricating the floppy drive) revealed a Novy X103 expansion...
