so i just recently fixed my ps3 from ylod and i had to open it. i also had a game stuck in the disk drive so i decided to open it and get the game out. i am happy the system works but when i put in a dvd it just takes it in but showes no sign of reading( the thing in the top right isnt spinning) the blue light blinks for about 2-4 seconds then goes black and nothing else happens until i eject the disk. i just want to know how can i fix this if you know and i would rather buy a new ps3 than send it in. btw i have a ps3 phat.
