LC Motherboard

#1 Fri, 12 Mar 2010 - 00:54 68kMLA

I've had such rotten luck with getting a working LC motherboard, that if this doesn't work, nothing will.

I call this a super conquest for me, even at $25. :beige:

They could go bad sitting on the shelf, but probably not if kept in a cool environment. Good luck with it.

LC motherboards are pretty easy to recap, I still have a LC 3 I did if anyone needs one bad enough.

Wow, I'd almost be tempted to leave it sealed!

Do I have to use surface mount capacitors? Or could I use one that's the same rating, but just solder the wires to the pads? My hands shake too much and I have the hardest time trying to get any surface mount caps soldered on. On top of that, I need a new soldering iron. My $10 one doesn't get hot enough to melt the solder anymore, even though it's 40w. :-/

I must be the unluckiest guy when it comes to LCs.

Man did I get burned on this motherboard. It was not new. It was not sealed. It does not work. >

Looks like it was a return part never returned to Apple.

Since it was sold As-Is, I can't do anything about it. Sigh.

I get a chime, but there's a horrible sound coming from the speaker; almost like someone is adjusting their AM radio trying to get a signal. Anyone run into this problem?

Leave him negative feedback. The item is not as described. As-is is something different than the description.

Before you leave him negative feedback, I'd try and get onto him first, yes the board was sold "as-is", but you were told that it is a sealed, brand new part, and it is not.

That noise is a dying capacitor tied to the speaker, same noise I heard on a used unit that died (same board I recapped and works fine I have as a spare). Asuming nothing else is wrong you can recap it and use it, but I would be pissed if it was sold as new and it is used and needs work.

I haven't been able to check the lone parts LC that I have; sorry.

But maybe the motherboard caps leaked while it was in the box. It's certainly possible, given the age of the motherboard. Like U_K said, it's a sign of leaking caps.

If I were you, I would give recapping it a shot.

Well, I tried recapping and, of course, one of the pads came off. I now have three useless LC motherboards.

just scrape some soldermask off of the trace with a knife and be careful

Use crazy glue and stick the ripped off pad back to the board, let dry. Put a small drop of flux in the crack between the traces and solder a bridge, then solder the capacitor to the pad (not as hard as you think).
