My PS2 Slim Won't Turn On

Check the plugs. Even if you plugged them in correctly, the connections at the back of the PS2 can come come loose. Dust may settle among the connections, preventing them from plugging in fully. Remove the connections at the back and spray canned air on the plugs and sockets. After you have cleaned all the connections, plug them all back in as far as they will go. Try to turn on your PS2 Slim.

Remove the outer casing. Using a screwdriver or a sharp knife, disassemble your PS2. (See References for a guide to disassembly.) The power switch may have moved away from the circuit board. Move it back into place and replace the outer casing. Turn on your PS2 Slim.

Check the power supply. Depending on which country you are in, the voltage will differ. There should be a label somewhere beneath the PS2 that says exactly how much voltage it should be receiving. If it isn't getting enough, it simply won't turn on. To fix this, you can buy a voltage converter online. If it was getting too much power, take it to a professional for repair.

Check the motherboard for a short circuit. If the motherboard has shorted out, take it to a professional to replace the motherboard.

If none of these steps works, replace your system.
