PSone Power Supply problems

[Tupin]

I got a PSone, and it only turns on if the power supply connector is turned a certain way or if propped up. I think it's a fault of the power supply itself, but I'm not sure because it works fine once it's propped up. Any ideas?

It sounds like a cracked solder joint in the system, it should be easy to fix if you reflow the solder.

This is pretty common in older consoles. Repeated stress cracks the solder joints on the power pcb connection. Reflow them and you should be all set.

I'd imagine the solder pad has become removed from the rest of the PCB since adequate solder is usually enough to prevent it from cracking on its own. Solder is quite flexible, fiberglass PCB isn't.

Worst case this means running an additional wire to insure a connection.

But usually it's just the solder. And by the way, just in case anyone doesn't know, reflowing the solder simply means to melt the solder that's there with a soldering iron and letting it resolidify. You don't usually even have to add more solder. It only takes a few seconds.

If the solder pad has been lifted from the board or a trace broke, then you might want to solder a wire as APE992 mentioned but more than likely it just needs a reflow.

Repeatedly reheating leaded solder turns it more and more brittle and slaggy (I made up a word!)

If you have a soldering iron, solder, and have the system open to do the work anyway, just go ahead and add a little more new solder to the joint, or remove the old solder first if you have the tools.
