Question about Optoma MovieTime DV10 Multimedia Projector

3 Answers

Purplish-blue after 5 minutes of viewing ...?

I am a soldier deployed in Iraq. We cant get any decent sized TV's shipped out here, so I had a friend send over one of these DV10's last october. Until recently it has worked fine, but now it only plays movies for 5 minutes or so before the picture goes sort of purplish-blue. The movie still plays fine but the color is just off. If you turn off and turn back on, it works fine for 5 mins then again. From what I read around on the internet, i guess my color wheel is bad ? I dropped almost $400 on a replacement lamp to have as a spare, so I really don't want to go with a whole new projector... Can someone provide some sort of lead on getting a replacement, I can have it arranged to be mailed to me. Also, do you think it may be a matter of dust (I recall we had a bad sandstorm before the projector started acting crazy) and I just need to clean it? Please advise.

    Same problem as his, image turns purple-blue after a few minutes of viewing....lamp life indicator says the bulb is ok. Had the unit since 2006.

    exactly as above. works fine at first then decends into a blue/red/purple mush. sometimes it recovers a little. sometimes the image flickers.

    turning it on and off means it works at first then problem occurs again

I solved a similar problem by putting a small battery operated fan blowing directly into the IN vent (on the right side of unit). This completely takes care of the issue.

Now, I wish I knew what the real problem was so I could fix it...

First of all, thank you so much for your service. We here in the U.S. owe you a debt of gratitude. Now on to your problem. It sounds to me like the color wheel does have to be replaced. Perhaps you can contact this person to find out where to get the part as I cannot find one for you at the moment: http://www.fixya.com/users/marrie
God Bless and get home soon.

SOURCE: optoma dv10 color wheel

Hi mrjepps

The first thing to do would obviously be to try and clean it out , if we're talking about a sand storm it would be better to blow it out with a can of air or even a compressor - gently.

Then check if using another cable ( if you have one ) would be step two.Alot of the times using a different cable does the trick.

Should the problem however persist , I would rather guess this to be a faulty Mainboard rather than a Colourwheel.

Easiest way to determine would be to place your hand on the unit while it's running - if there's a vibration then the colourwheel is at fault. If you cannot feel anything , take out the almp and chech the colourwheel - should be easy enough from the lamp's side to gently spin the colourwheel and check it for any faults.

If you cannot see anything , then I would rather opt at looking for a replacement Mainboard.

Could you please get back to me once you've checked out the above listed steps and also tell me which country you would prefer to order the part from so that I can assist in this.

Good luck and thanks for using Fixya !

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

180/900 in the lowest terms


180/900 is 1/5 in the lowest terms.

Divide both 180 and 900 by 180. 180 divided by 180 is 1, 900 divided by 180 is 5. This gives 1/5.

Hp laserjet m1522f error 5 turn off and on


Hi, Error 5 is a Scanner error. When turning the printer on, have the lid up so you can watch the scanner movement. Does it move smoothly? It should go through a warm up and you should be able to watch the scanner movement. If there is a problem with the scanner, there isn't a lot you could do except. The service manual says the scanner assembly should be replaced. If it was my printer, I would try to take a closer look at the scanner assembly and check to see if the scanner unit is bound up somewhere, or maybe a drop of 3 in 1 oil on the scanner rails. Let us know what happens.
thanks
