Release the left shoulder button flex cable socket by using a spudger to pry open the tab.
Be careful to not break off this small black tab!
Using tweezers, slide the flex cable out of the socket. Do not pull on the black tab! Instead, pull the thin flex cable away from the connector (to the left in this image).
Starting at the upper right hand corner, use a spudger to gently lift the motherboard out of the casing assembly.
The motherboard is still attached to the casing by a connector on the back of the motherboard. Do not pull the motherboard all the way out, or you may damage the connector.
Lift the motherboard out and identify the OLED connector still attaching the motherboard to the casing.
Holding the Vita on its side, use a spudger to gently pry off the OLED connector from the motherboard.
Be sure to hold the motherboard while you release the connector as this will free the motherboard. If you are not holding the motherboard, it will fall.
it should be noted that the memory card should always be taken out before separating the case. I just broke my memory card slot by having a card in there while I was opening the case, there's a tiny bit of overhang that will pull the slot off the motherboard.
Okay My original Motherboard power connector broke. So nothing was wrong with it except the Power connector.
My first buy of the Motherboard screen connector broke off.
The Replacement works well, however the Touch input isn't working, unless I restore the device. After a certain amount of time it becomes unresponsive.
Do anyone have a fix before I get a 3rd replacement.
