next flip the entire lens assembly over so you can get to the underside of the

focus lens, you need to pull part of the q-tip's cotton bud away so it's small

enough to fit in the opening to clen the bottom side of the lens.

and that's it your done the laser will play like new again.

 

you can also do this with the benq & liteon drive's but they use glue to hold the

focus block in place, you just need to re-glue it into place after your finished

cleaning it. don't use super glue it will cause you nothing but problems.

 

 

good luck
