The television itself has never been dropped nor has a surge hit it.. But for some reason the screen is dark when warming up and once it warms up it "flashes" black when the screen is too bright... Basically meaning that black comes over most of the screen seeming to be in the brightest parts of the picture;However when the screen is dark the t.v. appears to be working fine... And also when the menu on the t.v. is in operation the screen does not flash.. It is as I said before most bothersome when there is a bright picture.. not so much a problem when it has a dark picture.. I haven't the slightest clue as to what could be wrong with it.. and I can't turn the brightness down on the t.v. itself to see if that would fix anything because that option is shaded out of the menu and set to 90 and cannot be changed... (that I know of). Any help would be magnificent thanks!!
