SOURCE: benq 7220 display wrong color

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

SOURCE: My benq w600hd has suddenly

Hi,

First you need to check the prism.
If the prism is mounted properly then you need to check the light filter(s) on the lcd panels.
The light filter determines the color, if the filter is not placed properly you will have the color problem.
In order to check the filter take the top off, then the main board off and the lens off. The lcd panels and the filters are attached to the prism. Remove the filters and check if it is proper. If it is not proper replace it.
If you still face the problem, then I am sorry to say that you need to replace the lamp inside projector which will cost you $200-300.Replacing lamp will solve your problem.

Hope this helps.

42" LG TV works good except for watching videos with a DVD/VCR player. Videos are shown in black and white, no color


Colour problems like these are usually caused by using a TV and DVD/VCR that use incompatible "colour systems", the result of operating a display device (TV) and source (DVD/VCR) that are from different areas of the world (that don't happen to use the same colour system). https://support.chinavasion.com/index.php?/Knowledgebase/Article/View/272

"Multi-system" display devices and sources are available (but getting increasingly difficult to find) which will correctly display incompatible colour system material. The more convenient way nowadays, with cheap and powerful PCs processing capability available, is to convert the programme material from one colour system to another (not in real-time) with computer software. Other than the software, the other requirement is equipment (an adaptor) to convert the original video to digital form - i.e. something that can be stored (and then software processed) on a computer's hard drive.

Only BLINKING COLOURS LIKE RED WHITE BLACK


If the problem is with laptop monitor, try restarting the computer. If problem remains, try connecting your laptop to external monitor to see if problem is with laptop monitor or with display adapter.

If picture also like this with external monitor and with laptops own monitor after reboot, possible HW issue can be expected.

Hey, have you bene able to try another monitor and see if its the same thing?

I have a vivitek projector which produces white and black horizontal lines through the image. The menu will not display and neither will any input. What exactly is the problem? I have tried...


I've got the same problem with my NEC LT75Z DLP projector.
I am currently trying to fault find the unit, but need extender cables and special plugs and sockets to achieve this.

It will most likely be a partial power supply fault or a processor board fault, since the lamp comes on and the leds and fans operate, and the colour wheel spins correctly.

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!!!
