I dunno where this post rightfully goes to.
So I'll just try my luck and post it right here.

Does anyone know how to fix or clean the faceplate buttons on PSP ?
Meaning the triangle, square, O and X buttons.
I recently found out my O buttons is getting a bit faulty.
It still works, but sometimes it makes gaming a bit hard.
I tried looking for DIY videos, but they weren't exactly informative to say.

And without clear info on it, I don't really want to disassemble my PSP, just in case I make it worse.
Does anyone know if any gaming shops in Lowyat provides repair services like this ?
Or even better, just any shop will do, as long as they don't screw up my PSP
If you guys can provide a very very informative video, that would be even better so I don't have to go that far to Lowyat to get it fixed.

If it helps, my PSP is a half cracked 3000 series.
