It could be that your tv is getting ready to die.I would limit how much tv you watch till you can get a new tv.
My TV Makes A Buzzing Noise When I Turn It On Its So Loud That I Can't Hear The Shows I'm Watching. Its Done This Before About A Year Ago But Went Away Now Its Back Ans Still Hasn'T Gone Away. Does Anyone Have An Idea What It Is?
Take it to the shop there not that high right now.or just get you another one.I That will drive me up the wall. Get it fixed..if you wont it... Good luck.
