I found a color wheel earlier this year at www.vancebaldwin.com for about $90 and replaced it myself in about 45 minutes.
You can do it too!
-Before opening and working on your tv:
ALWAYS UNPLUG THE TELEVISION!
-I recommend someone to help you pick the tv up and turn it around so you can get to it.
-Also, have a digital camera close by to take pictures of your set before you take something out or unplug a wire.This will help you when piecing the set back together.
-It has been a few months since I did this so screw-counts are hazy.
-Remove all the screws from the back-bottom panel of the tv.Pay attention to the different kinds of screws that come from the different areas of the panel.Take pictures or put the screws into proper holes on panel once it is removed,while it is still fresh in your mind.
-Looking at the back of the set, on the far right, you see the lamp housing.Moving to the left, you see the color wheel "tray".
-Looking at the bottom of the tray,there may be 2-3 screws to unscrew. Basically,the whole tray slides out so you can actually take it somewhere comfortable to work on the wheel. Look for the best way to slide that tray out.
-You will have to unscrew some screws and unplug a couple of wires...
Take Pictures!
-Once you slide out the tray with the color wheel housing,remove the top of the housing.It may be 2-3 screws.It should be obvious where this is.Take the top off and you will see color wheel sitting in it's resting spot.Unplug it and take out screws holding wheel in place.
-Now, remove the wheel.NOTE:how the wheel is sitting in there so you can place the new wheel in exactly the same way.
-You may have heard warnings about touching the wheel with your fingers.I do recommend to handle the wheel carefully.However,I used canned air to blow some dust off of my new one and some liquid came out of the can and onto the wheel.I used Windex, a Q-tip and a Kleenex to clean the wheel and it worked fine.
-Carefully place wheel into the housing and make sure it spins freely and cleanly so it is not rubbing on anything.
-Plug wheel into it's receptacle and re-attach housing.
-Slide tray back in and begin re-attaching any wires you unplugged and screwing screws back in as you piece the tv back together.
-Make good use of your pictures you took.
-Once I got everything back together, I plugged the tv in and let the wheel sit in there while the tv warmed-up. Probably not necessary, but the wheel was delivered in winter-time and I wanted it to be room temperature before I fired it up.
-Turned on the tv and it worked great. Now I can hear the movie and not the wheel humming!
-Good Luck! and Congratulations!

I actually just got my color wheel replaced, but it was under warranty. The guy took about 15 minutes to do it after having to remove like 30 screws, witch took most of his time. it was very simple and should not take 3 hours at all...

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!

Flashing in Blk,Wht, and a little color


Sounds like maybe your color wheel needs to be replaced. If you have noticed a humming noise in conjunction with the intermittent colors, then that is most likely the issue.
My 51" Vivitek started to hum loudly about 2 months ago and I kind of ignored it ,but it got so loud and annoying I had to do something.First changed the bulb and then bought a color wheel at www.vancebaldwin.com .Login as guest and then enter your model number into corresponding box.They have a few Vivitek parts.
I replaced my color wheel myself and it works great!
I'd be happy to help any way I can.
Good luck!

Color wheel price for a Toshiba 52HMX85?


Hello jjoana,

My shop charges the labor fee of $60.00 per hour and fraction of an hour. So a 1 hour 1 min job is charged as 2 hours. This is just the cost of labor. $60.00 is an average I took from 10 sampling of TV repair shops when I was developing my pricing scheme . I hope this gives you an idea of the labor charges, There maybe other fees attached, or depending on the shop the cost could be higher or lower.

I hope this helps,

Thank you,

Vivitek 51'' DLP color wheel


it's not hard at all, trust me. but you have to go at it slowly when doing it for the first time. it's just about unscrewing and disconnecting wires. Nothing that is hard to reach either. I can help you step by step if you want, just email me.
However, my problem is to get the correct color wheel!!!! I have ordered twice from Vance Baldwin now and looks like they keep shipping me the wrong color wheel? first, the new color wheel does not look like the old one, then its wire connection is shorter making it harder to connect and then when done, the tv switches all the colors around: so red becomes blue and blue becomes red! what's going on???? I tried it twice with 2 new color wheel?I gave them the correct model number along with the serial number and they assure me the color wheel they shipped me is the correct one but I swear it is not!!!! so what's going on?
If anybody has an answer on how to deal with this, please let me know! here is my email:
chuericly@gmail.com. Thanks.
