suddenly a couple days ago, nasty wavy lines all over screen. sometimes looks like splotches of wavy lines or spots all over screen. what's the deal with this effect? seriously do not think it's the lamp, not old enough, but at least more than 200 hours of viewing. beginning to think the color wheel is the problem, using tv's remote to fix or return to factory settings (showroom settings) doesn't work. calibration research a bit techy on the subject. need this fixed before the super bowl
