The PlayStation 2 (PS2) has a modular construction, allowing it to be quickly opened to add or remove components. This can cause the power/eject ribbon cable to unseat itself from the motherboard and disable the PS2. You can repair the ribbon cable by reseating it into position, although you will have to open the PS2’s case, which voids the Sony warranty. You will need a few tools but no electrical skills.
Remove the power cord from the PS2. Remove the audio and video cables from the PS2. Remove the controller from the PS2.
Put the bath towel on a table. Put the PS2 face down on the bath towel with the controller ports facing you.
Put the tip of the utility knife beneath one of the four rubber feet on the bottom of the PS2. Wiggle the tip of the utility knife to loosen the rubber foot. Pull the rubber foot off with your fingers.
Repeat this procedure with the other three rubber feet on the bottom of the PS2.
Repeat this procedure with the two plastic nubs on the bottom of the PS2 that are in the middle.
