Hey guys I have taken apart and put back together a LOT of macs, but I have never soldered anything to anything in there and I'm a little nervous here. I recently bought a used iMac G5 1st gen 1.8ghz and it boots up and operates quite well for extended periods. This week it started turning itself off spontaneously. So I opened it up and looked to find two bulging capacitors next to the heat sink. Bummer. I did some research and learned that the capacitors can be replaced. So I bought them, and a solder station, and I'm gonna give it a go. Gotta check the PSU as well, I think. Anyway, does anybody here have any experience with this procedure? Any tips or advice would be welcomed.
Google "Motherboard Capacitor Replacement Tutorial"; you'll get a lot of useful hits...it's not only Macs that are affected by this. My own recommendation is 'patience pays big dividends.' This isn't a particularly technically difficult job, just one requiring precision, and attention to detail.
One of these: <http://tinyurl.com/yadel8o> and/or some desoldering wick, like this : <http://tinyurl.com/ybsxq7z> are invaluable tools in this process.
Also a pair of these <http://tinyurl.com/ycqwpbg> or one of these <http://tinyurl.com/ydvyhxs > makes life enormously easier on the eyes in this process. The lamp solution helps also to keep the smoke out of your eyes.
