My PSP's X button doesn't seem to be working properly. It only respond when I press HARD on the X button.
All the other buttons respond like it should.

Is there a way to fix it myself or do I have to buy replacement buttons or send it to repair?

yea but u need to take off the face plate all that stuff and the warranty sticker dont do it unless ur warranty is out of date

yeah if its still on warrenty you can go to shop where you bought and if you dont have warrenty left you can try it yourself

i bought it 2 years ago so theres no warranty.
the buttons sometimes work but the response is lagging by two seconds
otherwise i must press down hard for quicker action

that sucks x is like the most important button

If you don't have a clue, don't open the faceplate your ownself just send it to the nearest Sony Service Centre. It' better to pay a little sum of moolah than buying a new PSP.
