Whats wrong with my PS2 and what should I do?

I am putting a link at the bottom to a site (run by australian modders) that gives detailed instructions for opening the ps2, cleaning the lens, and adjusting lens height, among other things.

Don’t open the ps2 unless you know what you’re doing around capacitors, get someone who does to do it instead. Don’t try adjusting the lens height until you have cleaned out all the dust. To clean the lens, use a q-tip soaked in propanol and rub it very gently in a spiral from the center outwards, then take the dry end of the qtip after a second and lightly touch it to soak up excess liquid.
