Replace lamp on dlp tv

Your color wheel drive motor is gone. So is all your money. No replacements parts are available to those who got those TV's. You got scammexd!

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.

This happened to me also. I just made the deadline to receive a replacement lamp from Vivitek by 2 days, because of the warranty. If not, I would have had to pay $250. This happened in 2009. My replacement went out in Dec, 2010 and I can't find a replacement anywhere. Order a new lamp, hope this works.

You need to replace the ballast board the powers the lamp.

my vivitek RP56HD22A 56" dlp tv has a new lamp and will not turn on. when i push the on button is whines and wont come on

The first thing to check on any TV that has a replaceable lamp is to make sure the lamp door is back on and seated correctly. You also need to make sure that the lamp is seated all the way in. The lamp door and in most cases the lamps have saftey switches they have to activate for the TV to work normal.

I suspect the lamp to be at fault.

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!

On the side of the TV press the menu and volume up buttons at the same time for three seconds. The 'reset lamp timer?' will appear on the screen. Press the OK button to accept. You're done!
