I have a Sony multi disc Dvp nc800h. This is the 4th one I have purchased, and each reached a point when it would not load a disk of any type. I took of the top and cleaned the laser, but it still gives the message No Disc. I've never paid more than 125 dollars, and when working their the best. Is a machine this inexpensive, worth having repaired by a pro?
