Capacitor number of the board.

Number of capacitor on the silkscreen.

I know see I said that really really bad. Sorry bout that. And that it was very bad wording...

FYI these are called a reference designator.

So that's what they are called! Thanks!

My DV SE 400MHz definitely does. I haven't had it apart yet but the inner bezel is yellowed and I can see multiple large cracks through the bezel.

Interesting information... perhaps the difference lies in where they were manufactured, rather than the era. There are definitely a couple of distinct plastic compounds that ive come across, and at least in Australia, the crumbly Spindleresque stuff has always been in the 500 and 600mhz machines.

Welp. A recap to the PAV board and Video_B/D board did the trick! It turned onto the flashing folder and mac. So !!!!!!! YAYYAY. It still has a crinkling noise so not sure there. But YAYAYAYAY! I am really glad that did the trick. FYI I didn't do a full recap to the PAV board... Why? I didn't buy enough 1000uf Caps! But at least it works! I did hear the electrolytic sizzle. So I caught it in time. Is the crinkling noise bad? Thanks! Hooray!

Me might be dumb. The HD might have been sending me to spend gobs of money. When I plug the HD into my laptop via adaptor it doesn't spin! And when it is plugged into the iMac the iMac stays on white screen! HMMM!

White screen is Open Firmware isn’t it?
Maybe it’s hanging there with the HD plugged in.

I don't know... I will research that thought to learn more about it! Thanks!
