Hey all!
After spending some money getting my PSP-1001's faceplate, buttons, analog and the ring replaced. My analog was VERY faulty before, so I had it fixed.

Finally, it worked but it messed up again. So, I opened it up cleaned the rubber with a tissue and the analog worked perfectly. But later on, it messed up again so I cleaned the rubber and the analog again and it worked like a charm again.

Now, I woke up just to find it's faulty again, so I have to clean it again. What should I do to stop this madness!?

I have to sell it, so I must not use JoySens and the PSP is supposed to look new.

What should I do? :(
