Broken power adapter repairable?

post #1 of 10
Thread Starter 
So the laptop power adapter that my Grandpa has broke, he got a new one and it works but I was wondering if I could repair the old one. I can solder and am pretty good with my hands so it should be possible right? What parts do I need?

It is a Toshiba Part No. PA3468U-1ACA

You can find ones on ebay and those work pretty well. Bought two in the past for some old compaq laptops and they worked.

What exactly is broken?

I've fixed a few adapters where the wires have gone loose from the jack just by soldering the wires back on and heatshrinking, you'll most likely need to rip open the jack's casing to see if this is the problem. Ripped or cut cables are even easier to fix, just splice the wires together and insulate the joints with heatshrink or electric tape.

If it's something inside the actual adapter, I wouldn't bother unless you know how to debug electrical circuits.

I haven't opened it up yet, but I think the problem is within the actual adapter because it just suddenly stopped working, nobody tripped over it or anything like that.

It's basically a PSU.

So probably one of the silicon components failed. In which case you'd need a replacement. You'd need to find the exact same component. Would probably cost at least a few bucks plus shipping.

Or it could be the primary cap that's failed. That's trickier to match, have to get all the specs exactly the same or it won't work right.

How do I figure out which one failed?

There may be burn marks on/around it.
