2005 model Zenith 50inch DLP YV makes a very loud humming noise when it is turned on. lamp in on but no picture


Vacume out where the fan is in the back of the tv. That should release alot of the built up dust. I try to do that to my tv atleast once a month. Hope this helps.

TV makes humming noise, lamp light is blinking, does not turn on


Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

No picture or sound


Hi, your color wheel needs to be replaced, the bearings fail causing the grinding noise, the new ones use "air bearings" so they are supposed to last much longer, video-tek

Humming noise


There are only two moving parts in this set. The fans and the color wheel. Typically when the color wheel starts to break or go on the fritz, the tv stops working. Count your blessings you've still got the picture. Open the back and turn the tv on. The color wheel is located on the optics block tray. The fans are very visible with the back off. Stop the fan for a second and see if the sound goes away. If not, you might want to start looking around for a replacement color wheel. Rivervalleyelectronics.net is a good place to start. Sometimes Discountmerchant.com carries them too. Be aware that there two different wheels available. If the fan is the culprit of your problem. Radioshack will likely have a replacement for you. If you need further help, post a comment or email me and I'll send you pictures of what to look for. Cfoley@hawaii.rr.com
Good luck.

Vivitek 56 inch dlp projection is humming. why and how to fix


In my experience, the humming means your color wheel is going. The bearings inside the wheel are probably giving out.
My Vivitek started humming a couple of months ago and first I replaced the lamp.
Still hummed.
I read in other forums that humming is linked to color wheels and that seemed like where the noise was coming from.
I purchased a new wheel online and replaced it myself...
..no more humming, the picture is great and now I can listen to the movie again...not the tv!
