What is the Deafult value of Rgb colourS

Try to emulate 9000K by your personal opinion. Be careful with white, use small step changes.

Your RGB settings has most likely been altered, resulting in some problems. Check your settings menu on the monitor itself and reset the settings to default. If that is not the problem, it's probably the computer's settings that has caused this change. You will need to go to the computers monitor settings and reset that to default to get back to normal colours.

If you are using a CRT monitor and you have lost the colour RED, then whats known as the colour gun is faulty. It can be replaced at a cost. However you might find it cheaper or economically sound to purchase a new LCD monitor.

Remember to also check your screen by pushing the menu key on it.

In the menu, under colour management ensure that all colours are set to 50%.

If it is then above colour gun theory is correct.

All the best!

Here is a list of reasons why colours on electronic designs might differ from printed designs:

• Monitors work in the RGB (Red,Green,Blue) colour space while printers use the CMYK (Cyan, Magenta, Yellow and Black) colour space.
  Designs look fine on a monitor if they are designed in RGB to begin with. Converting them to CMYK might make them look odd on screen, but they will print correctly, to a certain measure. It is difficult to sign of an image file that is currently in CMYK mode while viewing with an RGB monitor.
• Monitor settings differ.
  The designer was sitting in a darkish room when choosing the blue and his blue looks vibrant. The client was viewing the same design in a well-lit room, making the blue seem lighter. The designer uses an LCD display and the client uses a CRT monitor and the vibrancy differs. The contrast and saturation settings on each monitor might differ as well, rendering the blue with different values.
• Each printer in the world prints colour slightly different.
  Sometimes it is really obvious and sometimes it is almost impossible to see the difference. Normal desktop printers are definitely not something to do colour proofing with. If you print the design out on your desktop printer then a slight shortage on any of the colours will make the colour come out wrong. There are a lot of factors that can influence even the most expensive printing equipment. These include altitude, humidity, the current heat of the printer, age of the printer, quality of ink, the paper that is being used, special coatings on the paper etc. Even viewing the same printed material in different lighting conditions may make the colour seem different.

Tips on getting the most accurate colour
Go to your nearest printer company and ask to see their Pantone colour matching system. Each colour in the Pantone chart has a matching number. Most design applications have the same Pantone charts built in so that colour matching is easy. Read up on Pantone at Wikipedia. Make sure that the file is converted to CMYK (If not designed in it originally) before sending it to print. Some printer companies might ask for colour separation prints which the leading design packages can produce. It is also important for the designer to choose the correct colour management profile in the design package.

The CRT monitors use RGB signals for displaying colours, most of the monitors dos'nt have colour setting option, This situation can only arise whenever the RGB signals are equally of the same strength, this is an indication that the chroma section responsible for colour distribution of your monitor is now working properly, you need to examine the RGB circuitry of your monitor, one more possibility is the data cable (VGA) has been tampered internally.

it is very simple, by default in monitor circuit RGB (Red, Green, Blue) tube is installed. and in combination of both of three colors we are able to view colorful image. due to non functionalty of Red color u r not able to view red color in screen, either you replace picture tube or purchase new monitor. coz cost of this tube is equal to monitor.

pin no 1 - Red colour signal (Red colour wire)
pin no 2 - Green colour signal (Green colour wire)
pin no 3 - Blue colour signal (Blue colour wire)
4&5 Not connected
pin no 6&7&8 are (Grounds)RGB Returns
9&10 NC
pin 13 Hohizontal sync signal
pin no 14 vertical sync signal
Not nessasry other pins

Color scanning is a big technology. There are concepts like Hue and intensity, refer to wikipedia for explanation. There is something called source light (your monitor for example) and reflected light (your picture that is being scanned). After scanning properly, say you view on a monitor where the Brightness & Contrast are not proper, you will see the image poorly! To test the scanning scan absolute white and check the output. It should read the values 255,255,255 for RGB (Red, Green & Blue). If the values are 255,255,255 but still the image does not appear white on the monitor, it is monitor setting that is wrong. If the output is not 255,255,255 then CANON service personnel only can help. Any good imaging software will display the RGB values.

CANON uses LED light source and they have fairly long life as compare to scanner bulbs. It is okay if you use a powerful system, but it has limited role as the scanner does all the jobs and it only sends the data to the Comp. May further processing is better withe high performance CPU and large RAM.

hi slk,
im not sure of the exact values for your rgb that would restore you white balance but you can install Adobe Gamma. Hope it helps.

there are 15 Pins in Monitor cable which is connected to VGA port on the rear side of the Tower. First, we need to reset BIOS settings, and then try again - onboard video card only. for Add-on Video card try reseating video card in diff. slot if possible / reseat video card and try again. if it does not fix it, it could be the problem with Monitor RGB Connection - near the electron gun in the monitor CRT tube. resolder RGB , it will fix it.
