If your PlayStation 2 (PS2) video game console has experienced a power surge and will not turn on, chances are a fuse has blown and needs to be replaced. Fuses are placed in electronic circuits to prevent damage to sensitive parts of the circuit by breaking the circuit when more electricity than is needed flows. Opening your PS2 to change fuses will void your warranty if it is still active, so do so only if taking your PS2 to the dealer is not an option.
Remove the eight-to-10 screw covers on the flat side of the PS2, opposite the side with the logo. The screw covers are small rubber or plastic squares that can be pried off using the tip of a flathead screwdriver. Remove the screws and label each to the hole it was removed from.
Cut the warranty sticker that is placed over the seam near the power switch. This needs to be cut to allow access to the circuit board inside the PS2.
Turn the unit over so that the logo side is facing upward, with the start button facing you. Gently pull upward to remove the cover, exposing the circuit board.
Look in the upper-left-hand corner on the circuit board and notice a black and white wire protruding from the power supply, there will be a small tubular fuse located near this which can be removed by pinching and pulling it out with your fingers.
Locate the second tubular fuse directly in line with the first, closer to you. Both fuses should be checked for functionality with a multimeter, but may be visibly broken if no wire is noticed connecting the two silver end caps through the glass tube. Replace with fuses of the same capacity which can be found at your local hardware store.
Reassemble your PS2 in the opposite order, taking care to replace the screws in the same holes they were removed from.
Only replace fuses with the recommended rating fuses to avoid damage to the PS2.
Never open any electronic equipment without first disconnecting power from the unit.
