    Could it be your color wheel not your fan?

If you have compressed air give it a Good blow out, the dust causes the fan to hom you can even wash the fan in hot water but make sure its dry before putting it back.

I have a Vivitek RP51HD41-A TV. The TV keeps turning off and on. The color and sound is fine. I have replaced the lamp and this has not fixed the problem.


If its a DLP it may have a color wheel which could be your problem (the colors will change etc)

Color wheels move at high speed and if slow down set will shut down.

The wheel if there will face the lamp. If often if failing will make a high pitched whine or a fan like sound.

The bulb is less than 2 years old and it has been flickering for past six months. we always have to turn it off then wait 20 minuets or so then turn it back on. What is the problem? And can you help us?


zimmer3,

It sounds like you have a bad color wheel. It is not running the proper speed and causing the flickering. Usually you hear a humming sound also but not always.

I have a tip at http://www.fixya.com/support/r4160054-replace_color_wheel_in_dlp_projection_tv which explains how to change the color wheel and where to get the parts at the best price.

Thanks for using FixYa and for the great rating.

Being on for while color goes makes humming sound when turned on


Your color wheel is most likely the culprit. Mine also started humming and and it got louder and more annoying.
You could try cleaning it with an air can, but it sounds like it needs replacing.
I replaced mine myself last week and it works great!
Unfortunately, the site I bought mine from is now out of stock. for the 51" Vivitek I have, but they may have yours since they had parts for the 56" as well.
http://www.vancebaldwin.com was the site I went to.Login as guest and then type model number into corresponding box and see if they are in stock.
I changed mine myself and would be glad to give any help I can.
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!
