Hi, I was following online advice to try and change the settings on my TV so that I could play music and movies from my USB stick through the USB service port on my TV. I tried a lot of suggestions but nothing worked and a few days ago I was trying a suggestion that required me to access the service menu. I followed the instructions but when I went to turn the TV back on it made the noise to turn on but the screen remained plain black, not even a flicker. I've unplugged at the mains, turned it off and on and even used my remote and the instruction books to try and do a factory reset with only the buttons and no picture but nothing has worked. The TV was working perfectly until I changed settings so I'm furious with myself. Does anyone have any suggestions?? Thanks so much in advance.
