Thanks I did do that and cleaned up the smudges and it seems to be working better albeit still intermittently. Now sometimes when I boot it I get no sound and the disk drive doesn'…

The "leaking capacitors" problem afflicts many compacts. A standard troubleshooting step for these models is to open up the Mac and carefully inspect the logic board for telltale s…

that just means you didnt kill the internal power supply, logic on the other hand is a very fragile thing, you basically shunted 5 volts down a (less than) 3 volt data line and mos…

It is powering up. To a black screen. The floppy is getting power as well.

So after days of waiting for my Macintosh Classic II which was shipped to me via Parcel Post I finally got it! It started up perfectly the first time but after that every other ti…

Not sure why you reflowed all 2,000+ joints. Click to expand... False hope and I needed something to take my mind off things for a few hours.

Just to try helping, how many RAM sticks are there? The reason why the Macintosh IIcis might not be giving video is because you don't have matching sets installed. Find a set of 4…

It can kill it very easily if it causes the wrong voltage to end up in the wrong place, or something horrible like that. If the machine's not powering up at all, its more than just…

Damn. Is it possible to replace a dead component instead of the whole board? How can putting in the IDE Connector incorrectly fry the board?

The machine made a burning smell...unfortunately i'd say its toast.

I like the Mac Plus, it was the first Mac I owned, getting it in 1990.

heh a good reason to own a goodwill toaster oven, but yes last on the list

I just got word that an acquaintance has finally managed to pry loose a long-promised classic Mac. I had no idea what to expect from this or when (if ever) I would get it - the fir…

Im not Jim! Could it be the single fuse on the logic board? How dead is it?

While Working on my powerBook 150 today, I got it to a almost perfect condition. Put it back together and, a Black screen and a bad smell. On further inspection it seems that I hav…

As in trying to acquire any other skill, practice makes perfect. Grab a junk circuit board, and practice removing its caps. You'll quickly learn how much heat is too much, how long…

I've reflowed every joint on that board (literally, all 2000+ joints), just in case. Still getting a Sad Mac error unfortunately. I'm not having much faith in the future of this lo…

If I can get some documents describing the optimal settings for these, i'll be sure to give them a shot. Apple's service source documents show how to perform the adjustments, and t…

PMed ya again.

Well JRL, TO be honest your offer is very tempting, but I really don't want to spend any monies. And shipping from CA might be hell. If you are willing to pay shipping on your end,…

Just curious, how did you remove the old capacitors? I have just order a set of new capacitors for my Mac SE/30 but I am not confidence in doing the replacement by myself. I worr…

So not interested in my offer?

I'd say you may have torched the logic board.

The Hard Drive, smells, and the IDE connector smells on the MainBoard. The Machine is still outputting video. But just a blank black screen.
