Volume noise after warm up

I have a 32 in Proscan LCD tv and the volume makes a humming noise after it warms up.
Can't find any information on the manufacturer? How do I contact them.

YES! I had this problem and there are others here under humming.

Standing in front of the TV, make your volume zero.
Punch in --very quickly-- 9876
If it worked, it will open a new menu. Go down to the Backlight and enter. Move it up to 83 from 81.
Hit menu twice.

Now try it and see if your hum is gone! [I think I was starting to go deaf trying to hear the volume over the buzz!]

I will warn you to try it a few times. At one point it shut off on me in the middle and if this happens to you, expect the volume to be BLARING when you turn it on again. :-)

Volume making humming noise when on


there is a bad ground.
the hum you are hearing is ac getting into the audio.check all the rca plugs on the set are plugged in all the way.do not run them close to a power bar either.
sometimes a second unit with it's own volume is hooked up to the tv and then the tv volume is up too high because the other box is turned down.if there is a unit hooked up,turn it's volume up ,and the volume on the tv down,otherwise the tv will amplify the residual noise.cheers,ed

Hum in sound volume


It could be a few things. The first thing you want to look at is make sure that the microphone is muted in the mixer controls of your audio cards. These settings are located in the control panel. If you need the mic, look under the advanced settings under it and disable the 20 db option for it.

If that doesn't work I have a few other ideas.

Hum in the audio - 32'' Proscan 1080i


does the hum occur when playing a dvd or only when watching tv ? if the hum occurs only when watching tv, i would like you to disconnect the cable line from either the wall or the back of the cable box and see if this hum disappears. if the hum disappears call your cable company. you have what is called a " 60 cycle ground loop ". hope this helps.
