My 60" lcd projection tv wont turn on sometimes and throws a lamp light, and if i watch tv for a while and turn it off it wont turn back on and throws the red lamp light


The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.
