I think what you are really asking is this:

----------------------------------------------------------------------------------------

Hello i am unity.

I am new to the forum.

I have this Macintosh Portable that i am working on, Model 5120.

This badly needed some new capacitors.

Would any of you fine seasoned /experienced gentleman be able to help me troubleshoot an issue i'm having?

The issue is:

After i installed some new caps...

No apple bong when i try to boot the machine up, any help would be fantastic!

Thank You.

Well I would start off by asking you.

What caps did you change?



all of them are bad and need to be changed.

Next. How are you powering this thing up?

A fully charged 6v SLA battery i presume?

- don't say powerbook 2 or 3 amp charger.

next, you are saying your soldering sucks.

Well if its that bad then you really need to inspect your solder job here:



there are many little traces that run right by the pads there… when in the pad clean up

cap removal process maybe you now have exposed copper traces, and there are solder bridges.

Over all if your soldering sucks... you should remove all of what you did… and re-do it, so it doesn't suck.

the key is Flux + Solder braid, and a gentile pad scrub gets the pads looking new like so:
