How I fixed two PS2

How did I do it? I followed the excellent directions I found in this Ars Technica article. I had two rather old PS2 units, both would throw irritating "Disk Not Found" errors with certain games or DVDs. One of the decks was chronically gagging on this problem, rendering it nearly unusable. The other would cough up on specific titles; making loud clunking sounds while trying in vain to read the disc.

Anyhow, if you do read the article above, the article mentions the PS2 having 10 screws on the bottom. My early model PS2s only have eight screws to remove.

With both of my PS2s, it was not enough to simply clean the deck out, I had to manually adjust the lens height.  This proved a simple procedure, and yielded me two PS2s that now play as they did in days gone by.

Mind you, I'm not telling you to follow the instructions, I'm just stating what worked for me.
