What's the life expectancy on one of the controls? I have had mine since I picked up my second PS3 a few yrs back. Just last week it just decided to stop working. The night before no problems turn it on the next day and the triangle, circle, square and x buttons were not responding. My D pad and my sticks work fine. I checked out some youtube vids on how to fix controls. So I took it apart and cleaned it up. Charged if fully and tried to use it connected/unconnected to the PS3. The only way I can get the x button to work is resetting the control from the back and hitting the PS3 button in the middle of the control to start the control back up. The triangle, circle and square won't work at all. Anyone ever had this happen and got the control to work like normal again? Or is it a lost cause and I should just get a new one?
