Lifting up the Blue-ray player will also make the button panel pop out, disconnect the small ribbon cable for the button panel from the motherboard. <img alt="" border="0" src="https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_uVmECYpgEc11yDap4ZNnXpQLJjEJWlenhZsYBCWrhiyK2HHp4UUJWbXh_ahJ-9gWfiGUg6wAsf6w=s0-d"> Disconnect the two wifi and bluetooth antennas and detatchthem from the meta casing <img alt="" border="0" src="https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_sO_YmFYB9QCLM8oEtEoNVRVWuXmIMd-PGwlXyXBhyZRdXWY_JP7JFlghUe-FSKgkZNWyEtn9ytfw=s0-d"> Now unscrew the black screws : top left on the right side of the power connection right middle to the right of the large blue ray player connector or the battery, right above the hard drive encloseure -2 screws holding the Hard-drive enclosure in place, right bottom side where the power button board was(just above there) -1 screw in the center of the console Now gently lift up the PS3 wiggling it out of the bottom plastic case. do this very gently and scan around your Playstation for anything blocking the board from coming out! <img alt="" border="0" src="https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_u5gq4rUevfLLD6QHqoTThAp0V7mX8FabQuS6X2APeTxCx9y5RrzPpAxRxWrcM3d5eOozgJoZ15NQ=s0-d"> Now put the plastic case aside and put the board with the fan down in front of you, you will see 2 large clips mounted by large screws. unscrew these, now on the same side,unscrew all screws left.
