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.

My dvd player is making a loud humming sound when i load up a dvd. it is the phillips dvp5960


Does the DVD player still work, even though it's making the humming noise?
The humming noise may just be normal for that machine. Turn your TV up louder .
If the player doesn't work, the drive is broken, and you would have to send it to Phillips if your warranty is still working. If the Player still works, check to see if the disc is warped or cracked, this'll make the drive unstable, and make the noise.

Hope my answer helped :)

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.
