Iamge from the previous projection from RGB still appears when i switch to Video mode. why is it?

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.



Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

Here's what the User's Manual says:

Using the Remote Control

To advance PowerPoint slides with the projector's remote, you

must connect the USB cable on the projector's computer cable to

the computer. See page 8 for more information.

Point the remote control at the projection screen or at the front or

rear of the projector (not at the computer). The range for optimum

operation is about 30 feet. If you point the remote at the

projection screen, the distance to the screen and back to the projector

must be less than or equal to 30 feet. For best results, point

the remote directly at the projector.

If you are displaying presentations in Microsoft® PowerPoint®,

you can use the remote's Previous and Next buttons to navigate

through your presentation while in Slide Show mode.

O don't see why not. They are both female by default, as we don't want VGA pins poking out of the rear of our laptops to catch on stuff.
Don't forget to tell the laptop to switch to external screen.
Hope this helps.

This requires a converter. If the laptop has a VGA port, use an VGA to component video or VGA to composite video converter. See this site for some examples: http://www.svideo.com/pctocomponent.html . Do not use a VGA to component video cable - these are meant for projectors that use RGB signals.

If the laptop has an HDMI port, you'll need a different type of converter, like this: http://www.hdtvsupply.com/hdmi-to-component-adapter.html . Then set the output to YPbPr.

I hope this helps.

(I doubt your laptop has a video controller that can output a non-RGB signal.)

try to restart your laptop into safe mode with still the projector connected. notice if your safe mode desktop appears projected as exactly as your laptop's desktop screen. if so, you only need to further configure your display settings.

Hello willardlang,

This is because of the type of Component Video being used. Let me explain We got so use to the term RGB to explain component video we for got that there are two standards for component video and they are not compatible. These two standards are Component Analog Video (Y, R-Y, B-Y) and Component Digital Video (Y/Pb/Pr) or (Y/Cb/Cr)

Now, the problem is they never told us the public which one to use and when, they only told us RGB. Now to complicate things, you have have to figure out which one to use. So here is a helpful yet flawed hint:
If the TV was made after 2003 use Component Digital Video (Y/Pb/Pr) or (Y/Cb/Cr)
If the TV was made before 2003 use Component Analog Video (Y, R-Y, B-Y)

Yes this is flawed but for the most part it's good.

I hope this helps,

Thank you,

hi try using the function key to toggle the display output form the laptop.every laptop when connected to an external display like projector works in the multiple diplay mode.in this mode the laptop vga output can be seen in 3 modes------ only laptop screen, only external deipaly(projector) & both laptop & projector.check this & this should work fine
any further help contact shyam +919867355202

1.
Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
1.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
3.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
4.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).

the switch is onthe rear to select RGB or video S

It sounds like the tv maybe in RGB mode.
