No color,,checked all settings , all I have is black and white

Try viewing a source such as your cable box or computer on your TV. With this source playing, open the TV menu option. If the TV menu is also in black and white then there are a few components inside a plasma TV that can be causing your problem. If the menu appears in color but the video source your watching is in black and white the problem is probably with the source, such as your cable box or computer, rather than your TV. If the video and menu are in pure grayscale and the image is still clear the problem is likely the main board.

Hi, I bought a second hand HP VP6315 for an xbox 360. It works perfectly for 15 minutes and then turns from a colour picture to black and white. It has approx 1700 hours left on the bulb and is connected...

DLP projectors use a color wheel to add the color information to a black and white image. If the wheel doesn't work correctly, you get wrong colors or no color at all. I've never worked on one of these, so I don't know if the color wheel is a separately-replaceable part or is part of the lamp module. I haven't been able to locate a service manual or full parts list to check further, but I'll post a follow-up if I find more information.

The usual problem is that the color wheel motor goes bad and it stops spinning, but there could be other electronic problems as well. It could be simply a matter of bad connections that act up after the unit's been running for a while (thermal trouble). You can try researching this model further on the Web to see if anyone can provide detailed parts info, or see if a service shop in your area works on these. And as I said, if I turn up any more information I'll add it.

Good luck, and thanks for using Fixya!

My Infocus 4805 is just showing the INFOCUS logo and not showing the picture from the TV. all connections are correct but no

Powering On
  • If your InFocus 4805 projector is having a hard time powering on or doesn't power on at all, it could be one of two things. Due to the extreme temperature of the lamp that causes the temperature of the projector to rise, every InFocus 4805 projector has a cooling system. Check your projector's cooling solution, as it may need to be replaced. Also check the projector's fan---if the fan doesn't spin, the unit will not turn on. If the problem is the fan, you'll have to get it replaced. You can do this at the same place you bought your projector.
  • The Lamp
  • If your InFocus 4805 Projector powers on but does not project any light, the lamp will need to be replaced. All projector lamps must be replaced at some point---how often usually depends on how much use the device gets. Simply order a replacement lamp, unscrew the old one and screw the new one in. The projector will then work like new.
  • Color Wheel
  • If your InFocus 4805 projector powers on and is displaying images but the colors on the images appear warped or are not in the proper places, your "color wheel" will need to be replaced. The color wheel is a small device that essentially acts like a prism. Light is projected through it and it displays the appropriate colors on screen the way they appear in the original video source. Order a replacement color wheel that fits your model and use your instruction manual as a guide as you swap the old one out and put the new one in.

    It's probably the color-wheel problem. Maybe the color-wheel stucked because of dust and/or color-wheel sensor is covered with dust.

    The simple way to check this, without reinstalling drivers or so, you just tap menu button on remote. If you will see only black-white user interface it is definitly color-wheel.

    Good luck.

    If you're getting a black and white image with or without source, it's probably the color wheel. Do you hear anything loose inside the projector? if you do it's the glass fragments of the broken color wheel.

    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!!!
