Does anyone have any experience with the PAVs on slot loading (Rev. E and later) iMacs? Not the rev. A-D iMacs, those use a completely different design.
I've got a 2000 iMac G3 350Mhz. 160 RAM, 10gig drive that I salvaged from a dumpster eMachines. One of these:

These iMacs have no fans in them (!) and relied on convection cooling for the sake of fashion and quiet operation. These things run incredibly hot! Typical Apple decision, putting form ahead of function. These things take 120V into the PAV (Power/Analog/Video), which is pretty much the chassis for the monitor part of the iMac. The motherboard is then fed 12v/5v/etc through the DCU (Down Converter). So pretty much, the computer portion of the iMac gets its power like this:
120V Wall-->PAV-->DCU-->Motherboard
Anyway, these iMacs have an extremely high failure rate. Usually the DCU or the PAV dies according to Google. I cracked mine open and saw the cause of death immediately:
The DCU and PAV are both completely populated by 85C G-Crapxon and Sh'itscon
The CRT, PAV, and DCU are all manufactured by LG.
Anyway, on my particular iMac, the screen kinda shimmers when I run it at 1024x768. It's unnoticeable at 800x600. I notice it happens mostly when there's heavy HDD activity, but sometimes it happens even when the HDD is idling. I was wondering if anyone with experience on these could tell me what's up? My gut feeling is that the DCU is on its way to shitsville and isn't isolating the PAV very well from the motherboard. Thoughts?
Recapping this one is gonna be a bitch, but I have to save it. My school got iMacs when I was a 2nd grader and I wanted one sooo bad as a kid since I used them all the time at school. iMacs stand out as a significant icon of my elementary-school years. I bought the one I have off Craigslist and it makes a decent music machine for my room running OS X 10.3.9 and iTunes 7.6.
