Ok, so I've been trying to fix my PS2 for a while now, but nothing is happening! So, my PS2's disk try got off the track, so I opened the PS2 up and put the tray back on the tracks, but now it won't play any games! I thought it was the lens, so I followed a guide that said to turn this white gear 1 click, put the disk tray cover on, then try to play a PS2-DVD, PS2-CD, and a music CD. So far, I'm stuck on getting a PS2-DVD to play! I've turned the gear countless times, and know I've gone around at least twice now, making sure the gear moved one space at a time, and nothing has happened! Do you have any suggestions? I am getting really frustrated! Thanks in advance.
