hi stephen, you will need to take this apart to clean the laser by hand/cotton bud & cleaning fluid but do not touch the laser(hand/finger's) else you will need a new laser,once you have removed everything & the laser is visible put cleaning fluid on the bud & gently brush over the laseronce you have done this,let it stand for about five min's then try a dvd making sure the disc is clean aswell,upon disc working unplug everything & replace all part's, best of luck steve
