HDTV, please

my current tv has been moved twice and though it’s only a few years old, it’s dying a slow gasping death. the picture isn’t sharp anymore and the speakers always make a sort of humming white noise. lately i’ve noticed the picture is projecting slightly larger than the viewable area of the screen, and the image is slightly tilted. i fear one day i’ll flip the thing on and it’ll *pop* and die.
