Help! my son has a two month old PSP bought in russia. all of a sudden, the right and left arrow buttons on the left hand side of the console are acting up. They WON'T work at all during a game, but they DO WORK fine when i push the home button and play around with the system. what gives? if the buttons were giving out (which they shouldn't do after two months, right?) then why do they still work in the system mode? any ideas you have for repairs would be much appreciated, as my son is in crisis mode!!! thanks.
