I have a hd61lpw165 big screen tv that makes a loud buzzing sound as soon a it goes on with no picture.


sounds like the lamp or ballast, check the lamp first to see if good, then if good, then probably the ballast is bad, but I think the sound or buzzing is coming from the ballast, so it's should be good.

Humming sound


Samsung states - A buzzing sound from your plasma TV is normal. It is caused by the electrical charges used to create the images on the screen. The buzzing, however, should not be so loud that you can hear it when the volume on the TV is set at normal levels.It is also important to determine the type of buzzing sound. A sound like a ground hum is completely normal. This buzzing can originate near the power cord connection or from the SMPS board position on the upper back of the TV. The buzz will be more audible as contrast increases on the screen, most notably when displaying an all white screen. If the buzzing sound is loud, you may have the Contrast set too high. Lower the contrast to reduce or eliminate the buzzing.You may also have loud buzzing if the rear of your Plasma TV is too close to a wall or other hard surface. Try moving your TV away from the wall until the buzzing is minimized. [1]
If the buzzing is at a higher frequency and resembles a crackling sound (like the sound of Velcro being pulled apart), and originates from the upper middle back of the TV, you likely have a failing SMPS board. Place a support call with Samsung to have the SMPS board replaced.FP-T5084 Have a known buzzing problem with a very simple fix.If the buzzing is coming from the left or right sides of the rear and the volume can be changed by pressing lightly on those locations, you are probably hearing the vibration of the grounding springs on the back panel. Call Samsung (or whoever) and have a technician confirm the problem. The easiest fix is to insulate the offending spring by applying some felt tape.

LOUD BUZZING/HUMMING SOUND- CAN HEAR OVER AUDIO


have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

19 in blue screen only sound works great


blue screen is the noise mute screen. however the audio is not getting muted and hence the buzzing....meaning the tuner on the TV is not getting locked on to the station/frequency

1. check your antenna if you are using one. Autotune
OR
2. Reconnect coax from the cable box to Tv and autotune.
OR
3.Use the Video out from the cable box and connect it to one of the video inputs on the TV. Switch your Tv to that component. Use the cable box to change channels (Best case scenerio)
