Thought something fell in my living room until I heard a fizzle and faint electronic burning smell. This happened when I shut the tv off, before the fan turned off. Fully expected the TV to not turn back on, but it did. Tried again this morning and still working. Strange. Pulled the lamp and it looks good. My guess is it's either the ballast or power supply going bad. Anyone have this happen, yet the TV is still working?
