Hello Samsung TV LED LCD UE55F6320 The image became whiter, as if we had added a translucent white screen in front. (l was play on PS4 and suddently this appear) I can switch the image source (hdmi1,hdmi2,tv,pc, etc etc) it is always the same thing.
Menu look like this
@jigsaw28 first thing you want to try and check to see what the menu s look like. If those are washed out as well it is either a bad T-con board or a bad panel.
it was the Tcon card I just received the new one, it work well ^^
