The laser may be need to be manually realigned.
What does that mean?
And no, I only open my PS2 to clean it.
Its very easy to fix, you need to open your PS2, then unscrew and take off the CD shield, then under that there shall be a little white dial/nob
there will be a small metal arrow pointing at one of the..?..notches? in the nob, mark this with a sharpie and then procede to turn the nob clockwise?(might be counter) until the entire disk laser drops and clicks
then gently place the CD shield back on top of the thing, and hold it down gently with your hand, put a CD in and test it
if all CDs will read in the browser then it is fixed
make sure you rescrew everything back and then close it up
I know it works, Ive fixed 5 PS2's doing this and they all play Blue disks, silver, gold and DVD/CD/PS1 disks
I think my instructions are a tiny bit vague on what the nob looks like, you might want to google a picture of it
