Humming noise tv makes


The hum comes from a bad 60 cycle bleed into the audio circuit usually from a bad capacitor or other failed component. It will need to go to a television shop for service, but I would recommend replacement. $500 and you have a new TV verses $400 and you still have the same old worn out unit. The other cause could be you have the audio and video cables reversed on a video input.

I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps

My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.


Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

My TV loudly hums when I turn it on


Ok, I just picked one of these babies up this past weekend. It was cheap, so I didn't bother with the research once i saw that it powered on and seemed to work.

It was sold very cheap because it was throwing codes, which the previous owner was told was a cooling fan. Due to my computer hardware experience, I decided to trace what the problem was. The 2 accessible fans were working flawlessly and silently, the 3rd fan (going to the input components) was stopped due to dust bunnies. A can of air and a complete cleanout solved all issues with the cooling fan codes. The loud annoying hum is the motor that turns the color wheel. Since I had everything out of the TV anyway, I decided to trace the sound which is actually behind the color wheel and sounds more like a bearing or mis-balance in the spinning motor. The color wheel itself is in perfect condition.

In the meantime....annoying hums are fixed simply by turning the volume on your tv or sound system up - it's barely noticable during normal operation and is only really annoying when initally turning it on.

Hope this helps someone.
