One day I went to play a new game on my PSP and it wouldn't play. My old games don't play either. The PSP has never been abused. When I put the UMD in I hear the PSP trying to read the UMD (buzzing lazer sound) then some knocking (that you can feel when holding the PSP). It goes through this cycle again and again. When I open the UMD slot I can see the lazer shooting a red light. Can someone please help me fix this problem. My warranty is done and I will be traveling soon (the PSP is my savior on trips).
