I have a HG281D Monitor that has about a 5 to 6 inch thick white bar appear across the screen. its opacity is much more opake on the right hand side and when i move my mouse through its almost like the picture hangs there even after i move the mouse out of it. i have taken it apart and visually inspected all of the capacitors and connections and didn't see anything wrong nothing was bulged or leaking. I have done some research and found that it could be the Logic Card? I don't know....
