Possibly you lifted off the contacts while desoldering. I have a de-sodering pump to remove the solder, but it was still a bitch to do.

might have to trace the pcb around the suspect buttons and find another contact point.
Edit: I read back and you started with a 100 watt iron. That could have done it.
What do you mean “trace the PCB”?
Follow the green lines from the non-working Button.
Trace, as in follow, where the line leads to.
You’ll find alternate points or something.
rtdzign, I have that SAME Pump.
Same brand and all that.
But like 15+ years.
Laugh.
And if you can’t find an alternate solder point, as a last resort you can scrape away some of the green coating on the trace to expose the copper underneath, and very carefully solder to the trace itself. Then stick a huge glob of hot glue on it to make sure it doesn’t go anywhere.
How should I scrape it away? I’m trying to trace and solder, but I can’t seem to find the right points, and I can’t solder the wires on, anyway, since they’re so damn small.
Yes, you can solder to the Trace also.
Yes, it thin and hard to do.

Gah… I ca’t get these stupid buttons to work. I scraped some ofthe pcb back to reveal the copper ring and soldered to it, but still nothing. I dunno what to do now… I don’t think I have the skill or steadiness to solder to the trace. 
Okay… I took some pictures. Maybe you can diagnose the problem from these…
These are the four that I did right (Triangle, Circle, R!, and R2)

And the rest…

Okay, it looks to me like you first of all have the button labels wrong. The four you did correctly are the R1, R2, L1, and L2. But other than that, nothing appears amiss with those.
Looking at the other buttons, the one at the top looks like you’ve completely lifted most of the trace. In this case it looks like you could save it by soldering to the thick little bulb of solder directly furthest right of the hole. For the two you still have connected, it appears you’ve soldered to the ground instead of the signal, so just solder on the other hole for those two. On the unconnected button, just solder to the right hole.
Edit: No wait, I have my buttons wrong. I changed my button configuration when I modded mine, so disregard what I said.
Square looks shot to fuck. I hope that blob of solder there to the upper right is a legit contact point connected to the trace. Otherwise you will need a multimeter to run a continuity check to find another point that connects the Square signal.
X it looks like the contact to the right is the signal. The left one is ground.
L1 and L2 it looks like you soldered to ground instead of signal.
This is a common ground controller right? Usually if it is not obvious in a common ground controller what side is common, I solder a test wire to a known common ground. With the joystick plugged in, i touch the other end of the wire to the unknown contacts. The one that activates the button push when touched to ground is the signal.
Earlybird I think doesn’t realize the Hori FS3 layout is not like a TE. So keep that in mind when reading his post.
Here’s a picture of what I’m describing for saving that square button.
So I did not realize the PCB in Diagram of Bomberman was different from yours.
Sorry that. :sad:
^ It’s all right.
Okay… I did what you guys told me to do and I now have L1, L2, Square, Triangle, X, and R1 working. O and R2 no longer work (which is weird, because they did before.) What’s the damn problem now?
Edit:// Nevermind. Ground wire came loose! It’s all wired up and working, now. Now I’m going to hot glue my contacts, seal it up, and post pics. I’ll be back in a while.
All right… I’m done!

YAY!
I knew you could do it.
Congratulations man.
Have fun.
May your Joystick endeavors soar.
just a quick question…
if i just wanted to replace the buttons,
all I have to do is:
desolder
pop out Hori buttons
grind tabs
put OBSF 30’s
solder buttons to pcb
?
Yes.
thanks, hmm but if i want to put in a stick later i would have to desolder it again anyway, so i might as well just install a stick with the buttons
hmm…
Make sure you have a dremel tool or you’re going to spend a good hour per button when you’re grinding the tabs away. I used a grinding stone and emery boards. It took forever. I’d also reccomend just putting in JLF or Cherry microswitches and changing the stock spring. It’ll save you a heap of trouble, and the stick will feel the same.
thanks, i’m gathering tools as we speak >;D
