I found a listing on my craigslist for an "apple Imac g5 all-in-one" that needed a new screen. It supposedly chimes: http://memphis.craigslist.org/sys/5175934325.html. The listing also says its requires a second restart to get it working. Sounds like bad caps. Good thing I enjoy soldering . My favorite (albeit 'miss speld' guide is here: http://www.instructables.com/id/Imac-G5-DIY-capacitors-repair/step7/Soldering-and-replacing/) A new screen is $30 (if it turns out to be a screen not the GFX card, which I have a heat gun for). What else?
