I've recently noticed a development of about 4 lines on the top of my screen and some red tinting on the bottom. The color is generally off all together. Is it time for a new lamp? In my searches for what exactly is wrong with the tv, I came across this "How To" guide. Anyone have any experiences with this sort of thing? Thank you.
