PS2 Wont read games

It could just be dirty.

Is it not reading anything at all? Or is it just not working most of the time? If it works a little bit, you can try cleaning it yourself for free. This voids the warranty, though, if it still has one. You also have to be careful not to break anything.

Anyhow, if you want to clean it out, first thing is to turn it off and unplug it. This may seem obvious, but I've got a friend that got burned pretty bad because he forgot to unplug it. Then get a small screwdriver. I used a glasses repair kit to do mine. Take all the screws out. There are a lot of them. Take the top cover off. BE careful not to pull out the cable (it looks like a little strip of paper) that attaches the top to the rest of the unit.

I'm not sure if you have to take off another cover after that. It's been a while. Anyhow, if you do, it's nothing to note. Just take off more screws and another cover.

When you finally see the lens that reads the disc, you're ready to go. Dab a soft cloth in a little water and wipe it gently. Then, just for good measure, spray the whole unit, in every corner and at every angle you can, with canned air before putting it back together.

Voila. It... might work good as new now.
