Humming sound from TV

My Philips 29" 2007 model TV is humming most of the time sirrespective of the volume of sound.

We can hear the humming even when the tv is muted or sound decresased to 0.

Observed same kind of humming with other tvs too earlier. I believe a solution exists.

Please help.

Thank you.

Hear a humming sound seemingly emanating from the back or bottom set. Is this from the lamp?


Its most likely the fan . Often just checking the fan blades for dust buildup then removing the dust will fix the issue, other times the fan will need replacement. You can get the fans for that model from www.tvrepairworld.com if you end up needing one.

Yes, its fan noise and you need to replace noisy fan.

TV makes humming noise, lamp light is blinking, does not turn on


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.

Tv makes humming noise when on. how can I eliminate or reduce the nose?


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.
