I'm looking into this... I should be able to get back to you shortly!
I've looked through the forum and cannot find anyone else with this specific problem. My screen recently started showing green horizontal bars across the screen... not solid, they actually look somewhat like oily water you might see on the streets... they show up sharpest across the light areas of the screen (when across someone's face it looks like some sort of tribal tattoo).
I've tried all inputs, devices and resolutions... it eventually shows up on all. I do have some photos, but cannot see how to post an image here. Here is a link to another forum that shows a very similar issue to what I am having... only my 'bars' are only green.. none of the purple, etc.
Any ideas on what this might be are appreciated!
