My Zenith-branded LG Electronics L1715S seems to have picked up a strange habit suddenly. It will display an image for about half a second before reverting to a blank screen. The power indicator stays green (i.e. not in stanby mode) when it does this. If I power it off, then on again, it will display an image for a half second before going dark again. During the start-up sequence, it won't display the POST screen, however it will flash the Boot-loader screen with all the smart/drive info. Once again, returns to dark. I tested it also by connecting it to my laptop--same issue, so it's not a virus or something isolated on my desktop. I've tried shining a light onto it, and that doesn't produce an image so I don't think the backlights have blown.
Anyone have any ideas?
