SE/30: logic board (bad capacitors?)

I recently got the much dreaded simasi mac upon booting my SE/30. According to everything I'm reading on line, this is most likely due to bad capacitors as they have a tendency to leak over time (or to just go bad due to age). There is one man on 68kmla who is selling capacitor kits for very cheap (starting at $10) but I have no idea about soldering. Does anyone know someone who would do it for me, OR does anyone have some helpful tips for doing it myself?

For a temporary fix for leaky capacitors, some claim you can wash your motherboard.

It would probably help if you posted a photo of your simasi screen.

And have you read though the threads linked here?

Take time to read through what I have linked on 68kMLA. It will give you a formal degree in SimasiMac and cap replacement. Smile

The same fellow who has offered his SE/30 cap set to us on 68kMLA has also mentioned it on Vintage Macs:

And yes, I purchased two sets from him, so I can vouch for this set being a good buy.
