NS-LDVD32Q-10A buzzing noise


Try another input and another source such as a DVD player. If you still get the buzzing sound, you could have a faulty power supply output or a fault in the audio circuit of the main board.

Buzz sound when tv is on constant


Hello; If you have a plasma TV, is fairly common to hear buzz noises. They can be always there or intermittent. They can get louder as the screen gets brightest. If the buzz is noticeable when you are at normal volume setting, the buzz is excessive and a PCB probably needs replacing. These buzz noises are almost never a sign of failure or safety. LCD TV's can also buzz, but the same applies. John

A buzzing noise coming from inside the tv but still buzzes when on mute but doesnt buzz when tv guide is up on the screen or when a channel is showing what time it starts


plasma tvs buzz a lot, depending on screen brightness. its probably normal but if you can hear loudly over your volume, may be a bad board or plasma panel. from behind tv, left side = y board, right side = z board, middle = power board ---- bad panel can buzz from anywhere... if you hear all parts buzzing, its probably normal plasma noise

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Buzzing


If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.

Plazma TV buzzing noise


I have the same problem I can hear buzzing over the volume of the tv into the 30 range. I've had a tech out 3 times and he's coming out for a fourth. He's changed to power supplies and is bringing the 3rd next visit. From what I've read it has either to do with power supplies or grounding strips.

Buzzing noise, sound but no picture


It sounds as if the lamp needs to be replaced. The buzzing sound you hear is the ballast attemting to fire the lamp.
