My gateway gt5404 says no rgb signal what do I do

RGB means Red,Green,Blue it is an old system for supplying video signal to a screen..

soumds to me that a setting has been changed on the monitor itself. play around with those and im sure you will find a fix keep RGB in mind

In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Not really, first check your connections, normally when you loose red a pin broke off the VGA connector.

If the panel died then its probably not worth while. The red panel is however, under the most stress.

1)your RAM may be loose connected 2)other hardware may be loose connected 3)your one of the hardware get dameged

usually graphics card fault

If the other monitor has no signal as well, this proved the video card is faulty and needs to be replaced.

Try cleaning the RAM as shown in the image below:


If problem persist, replace the RAM. Hope this helps.

Have you done something on your computer before that happen? Maybe change your display resolution? or video card?

Neichi could this monitor be set to receive dvi signals and not rgb even if he has the rgb hooked into the monitor? so in menu select rgb input?

Mitch, monitors don't conflict with windows generally usually they(windows os) will install a basic generic driver to run the monitor, and you should do this when changing monitors before you hook up the new one, your description really lacks any concrete description where are the "black and blue errors" what do they look like last I have had problems with modems interfering with video so I would remove the modem and see if the problem goes away.
