cleaning

My old 39000 series PS2 was having some problems playing a DVD tonight. When canned air and my Memorex CD lens cleaning kit didn't get it back to where it should have been, I took cleaning a step further. Since my console is long out of warranty, and has been since I bought it used, I removed...

for some reason my PS2 doesn't play DVDs anyomre. It would play them like a month ago but now it just says disk read error. Is their anyway i can fix that?
