Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

Some of the larger TV's are DISH ready, meaning that they have the tuner inside for SAT TV. The SAT tuners often have an internal fan that makes a humming noise. If it sounds like something other than that, you might have a bad component in your sound circuit that allows 60 HZ hum through the speakers.


If it is a rear projection LCG TV it has a fan in it to cool the bulb. You will hear the fan if you listen closely. It usually cannot be heard over the volume.


The fluorescent bulb and electronics inside make humming sound naturally. Kinda like when you turn on a lamp, and some lamps make a low humming sound.

hi there, you do have a big problem at your tv, the loud bang means a part is broken, maybe you will cost 50 % of the original price of your tv. ty

The horizontal output transistor drives a transformer that gives you the high voltage to light up the picture tube,either the transistor or the transformer have gone bad,sometimes both have to be replaced and sometimes the transistor fails for no reason by itself.Be safe and call for help if you are not familiar with tv service.
