Can any owners of the Sharp LC37P50E or the 32" for that matter please check to see if you're screen has buzzing noise. Specifically check around the air vents on the top lefthand side, looking from the front. I don't know if this yet another of these dreaded backlight buzzing noises that seem to plague a lot of LCDs or is it simply normal operating noise. It's not really noticeable during the day but you know how it is, once you've heard it the first time it never really goes away. It doesn't detract all that much but if it is a problem with mine then I'd sooner get it replaced as soon as.
