    My Toshiba ET1 has gone yellow!

    I can change the levels of green and red in the image, but not blue. Blue appears colourless or grey. I have just changed the lamp in the last 24 hours and I have changed all the cables and tried different input sources (PS2 and PC)

It sounds a lot like a bad color wheel if it was a DLP. IF it is a LCD then i would say one of the LCD panels is bad or possibly a connection problem that drives the panel or the connection that hooks up to the projector is suspect. Let me know if that helped you at all.It is strange that the bottom shows white though. Jay

It doesn't show red color. i tried to do factory reset. but still problem.


1.After turning on the projector, press "+" and "-" buttons on the control panel
simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3 While in Self-diagnostic mode, the screen will run a seven-color-cycle test as
following:
Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct.

Contact Dell if the colors are not displayed correctly.

Replacing the lamp module requires special considerations:
  1. Turn off the projector.
  2. Wait 30 minutes for the projector to cool down and then unplug it.
  3. On the bottom of the projector, loosen the two screws on the lamp cover and then remove the cover.
  4. Loosen the two screws on the lamp module and pull out the module.
  5. Insert the new lamp module and tighten the two screws.
  6. Install the cover and tighten the two screws.
  7. Turn on the projector. If the lamp does not turn on after the warm-up period, try reinstalling the lamp again.
  8. Press enter on the projector or on the remote control to open the on-screen menu.
  9. Press the up (c00589410.gif ) or down (c00589411.gif ) arrow to select Setup and then press the right (c00589412.gif ) arrow.
  10. Press the up (c00589410.gif ) or down (c00589411.gif ) arrow to select Reset lamp hours and then press enter .

Your correct about missing your primary color. this could be either your cable or the connection at the projector could have a bent pin on the port. not sure what your trying to display computer?

Color Wheel


I'm pretty sure if the color wheel spins with no vibration that it's not the colorwheel. I would have to say that your cable is bad. If it has been bent repeatedly near the connection that the wires could be breaking down. Try a brand new cable.

Yellow green display


you may have a bad cable. if it was an internal problem, the menu wouldn't be the correct color. you may also want to reset the settings to factory default, just to cover the resolution issue.

Flickering dots on Benq PB6200 projector.


it's not the lamp. if you've replaced the cords and still have the problem, reset the settings to factory default to make sure the resolution matches. if still not ok, there may be an issue with the main board.

Same problem w yellow on viewsonic pj550


Yellow is the mixture of 100% red and 100% green. what you may have here is a blue LCD failure in the machine. Try this to check. Open up PAINT and double click one of the colors on the bottom. now click add custom color. then in the RGB section put 0 for red 0 for green and 255 for blue. ok out of everything and fill the background w/ the blue. it should be a VERY intense blue, if its white or or kinda blue, you have an LCD issue

Thin vertical line appears on projector


I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

Projector only displays Black and White / No color images.


The problem is the color wheel. It may have broken or motor stopped on clear. Either way the image will remain unchanged just without color. It will need to be sent in for service. Not an unusual problem for BENQ. I have had 3 that have come apart after making a loud whirring sound. Good luck getting someone with BENQ to help they are horrible when it comes to service. Buyers beware!!!
