Follow the above linked tutorial on YouTube to learn how to clean your PS2's laser, OP. It's the first step(WAYYYY before the 'height adjustment' that Mr. Hockey recommended)to try before trying ANY other methods, since screwing up the height can have detrimental effects on your games.
Namely, if done incorrectly, it CAN cause the laser to scratch your discs in a circular pattern.
Oh and to whoever has broken(as long as they're DRE only) systems, let me know what you might want for them. The going rate usually is $15-20, give or take, which is just system only.
And, I only take systems if the seal is still intact on them and you haven't tried the height adjustment thing. If you've tried that already, then don't bother contacting me, since MANY people screw their systems and games up by doing that FIRST.
Hope the link helps you OP, as I know it helped me. Well, that and watching the one guy who owns a local game shop open about 5-10 PS2s the one day, which is what gave me the rocks to finally open my OWN system up.
Toughest part of the entire opening process is keeping the reset/eject cable from popping out of its slot. This can be prevented by popping the reset/eject button assembly out of the top part of the PS2. You just gently slide a flat screwdriver up under the side of the button assembly(which would be the right side of the system if it were still closed up) and gently push down or up on the screwdriver till the buttons 'pop' out.
This will allow you to set the buttons down on the table and put the top of the PS2 off to the side and just not have to worry about it popping out now.
If it still does though, while you have the case open, unscrew the 1-2 screws holding the controller/memory card ports in place and then lift the system out of the bottom of the plastic case ever so slightly and look under the right side of the system, with the front of it facing you.
You'll need a pair of tweezers to pop the cable back into its small slot.
Other than the reset/eject cable problems MANY people have with their PS2s when they open them, the entire cleaning process should take no more than 20-30 mins.
If you want to get the dust bunnies that sometimes collect in the 'grill' of the PS2 out, use an old toothbrush and simply stick it into the front grill on the PS2, then turn it left or right to 'pop' out the dust in one clump.
Hope this all helps you to get your free PS2 working like new again, but if the system still has trouble reading discs, then you might need a replacement laser($40-50 from many sites).
Go to
www.richspsxparts.com if you need replacement parts, since they have a quick and easy guide to tell you which parts to use, since NOT all PS2 lasers are the same.
Again, hope this helps......
