i think i know what the problem is.i have the exact same one as you the gdvd84wlcd,and its not been working for the last week,iv just spoke to a proffessional t.v repairer that had a look at it.He lifted the lid and were the laser is situated,it goes up and down during the movie,well its probably jammed on yours,so gently with your finger try pushing it down just a little,once its freed,try playing a movie.it should be right
