I left for work one night and the dvd player was fine! I get home put something on to watch and the dvd player is silent, churns a little and goes silent again and says "no disc" when clearly there is, I have tried different discs and the same thing happens each time, I've tried turning it off for a few minutes and turning it back on. Still the same, is there something I can do to fix this problem without having to take it t get repaired?
