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. :-)

None of the codes are working to set up my xfinity remote to adjust the volume. Is there a code that isn't listed?


No as the codes listed are for the settings in the remote if the code listed doesn't control the volume you need to get an updated newer remote with all the newer code sets
As you may find that one code controls the channel and another may control the volume and will be unable to use them at the same time

Can it be repaired and can I do it myself?


No, It's dangerous to repair a TV yourself, it contains hazardous electric currents. Most of such Electronic or Electric Gadgets have Hazard Warning on their Backside "CAUTION: NO USER SERVICEABLE PARTS INSIDE, RISK OF ELECTRIC SHOCK! DO NOT OPEN!!"

So, please consult Authorized Service Professional to repair your TV.
