    Hello Misha, I watched your video about Sony nh-700 repair, I own this model but I have a problem. My lcd screen is damaged. It spilled, I had it in the back pocket of my pants and I gently sat on it Do you know if it is possible to buy and replace this screen? Thanks in advance for your reply. Greetings Pavel

      Hi Pavel,
      I’m so sad to hear that your NH-700 got damaged.
      The only way to get spare part if to find DEAD NH-700 or use remote only 🙁
