Yesterday i ve noticed a logo stuck on my 435xde. I though it was image retention and i ve let other channels play for hour but I ve checked it again today and that "S" logo is still there. My xde has 235 hours and i thought it was very difficult for a screen burn to appear after these hours. I never left that "S" channel on for more than 2 hours. It s logo is a bright white "S" and now it s stuck on my new display. Contrast is at 25 and brightness +2. I m really really worried now. Do you think it s an image retention? You can only see it when the screen goes black. Jesus.
