Screen stays dark when booting up, iMac G5 20 EMC 2055
Screen stays dark when trying to startup. I hear the normal tone/chime sound, but that's it. Nothing else happens. I thought it was the hard drive, so I replaced it. Now when attempting to boot from CD, I get the same symptoms as before.
When I looked around inside, I noticed that 3 caps were bulging on top. One of these had some crispy brown stuff that had come out of it. The motherboard was replaced a couple of years ago, or so, at the Apple Store for free, to deal with this very issue. Now it looks like the same thing. I was told that the replacement board was "new old stock" meaning that it was manufactured around the same time and sat on the shelf all this time.
I'd like to replace these caps with new ones. I went to TheCapKing.com but they were out of stock. Sent them an inquiry. In the meantime, am I on the right track? Any advice? I'm pretty comfortable soldering the new caps in, I just want to know if I'm on the right track here or if I should be looking at something more. Any and all advice is welcome and greatly appreciated. Thank you.
