hey guys, i had a few probs recently with my ps2 when playing backups would skip, i saw info on these forums and various websites that adjusting the white cog near your laser and cleaning the laser can help. i did both of these but now my ps2 wont read anything. if may be useful to note that i did take the ps2 apart using the instructions from that cybermag site, and once id completed those instructions realised i didnt need to take it apart that much at all, and put it back together. is it possible i may have damaged something or is it to do with the white cog adjustment? any help would be much appreciated. thanks!
