PowerMac motherboard (logic board) shorted, help me fix it.

My PowerMac (G4 1.5MHz 512 original ram, 17') got wine spilled on it a week ago. It shorted out the motherboard, and the Apple Store confirmed it. Now, they said it would cost over 1000 to fix. I would like to know if anyone had any ideas of what to do about this incident. I can repair it myself if I have the part.

Who is "they"? Apple? A third-party shop?

What part do you need? How do you know that's the part?

A power supply for that model can be swapped out for $100-150 and you won't electrocute yourself.

Have you searched your favorite auction site or used Mac shop for a replacement logic board, which you will find for much, much less than $1000?

He's talking about a 17" PowerBook... a laptop, not a desktop machine. (The fastest G4 desktops were 1.42 MHz.) That makes the cost a lot closer to believable.

Since wine is sticky, and will remain wet longer than other spills, you might still be able to clean it.

I've posted the way I've successfully cleaned electronics (including Macs) on ask.mefi before, but the abbreviated version is:

1) Remove all power
2) Disassemble the machine into its' smallest components which are spilled upon and can be submerged
3) Fill a pan with distilled water
4) Submerge affected parts and agitate until the spill is gone - use a paintbrush with the stubborn parts
5) Empty the pan and repeat steps 3 and 4
6) Empty the pan and fill with 90+% isopropyl alcohol
7) Submerge affected parts and agitate for a few minutes
8) Remove parts and set on paper towels for several days with a positive airflow on them from a fan
9) Rotate and flip parts over and repeat step 8
10) Check for wetness, repeat 8 and 9 if necessary
11) Re-assemble, re-electrify and give it a try.

Since you're looking at a logic board replacement anyway, you might as well try and clean this one first. I second the third-party parts. One can usually find a parts machine from LCD damaged units.
