In Monitor Light Blue Colour is coming. - Samsung SyncMaster 793MB 17" CRT Monitor

Hi
Firstly - Is the cabling, mains and data cable, securely attached at both ends and the power turned on at the mains?
Secondly - If so when you press the monitor power button, does a light come on? (often orange coloured) If yes does this change colour when the computer starts its boot sequence? (often to green or blue)?
If no light can be obtained it is likely that the monitor is faulty.
If a light comes up on power up, but doesn't change colour during the computer boot sequence then it is more likely to be the graphics card that is faulty, or sometimes the computer PSU.
The easiest way to find out whether the computer or monitor is at fault is to replace the existing monitor with a monitor that is known to be in full working order, for example from another computer. (Or connecting your monitor to a computer that is known to be working)
Having isolated the faulty component it can be replaced and you should be up and running again.
Hope this is helpful, if so would you please register that with Fixya
Cheers

The exposure meter in your camera is underexposing due to the white background. Try adding up to two stops of positive exposure compensation. What you are seeing as blue is in fact grey - it may be an idea to calibrate your monitor as well.

It is possible your colour cartridge has cross contaminated the ink reservoirs. To check this take the colour cartridge out and turn it over to see the coloured pads. They should look red, dark blue, and orange ( the colours are actually Magenta, Cyan, and Yellow, but are concentrated). If any of the pads are pale or particularly green - change the cartridge.
If the colours look alright, your issue is probably that your monitor makes colour by emitting light frequencies so is bright, printed images make colour by absorbing light frequencies so will always be darker. There is always the issue of course that your monitor also has a colour "temperature" bias. Photo pros calibrate their monitors and printers to match.

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.

hope u r a professional..as u r handling chip-level repairing of monitor, knowing itz hazardous n dangerous..

however, check thoroughly for dry soulderings..(esp. at the crt base)..[this chance is maximum]..
see if the base is loose or faulty..
yes, it can b the 'chroma ic'..but don't ignore the associated components..(esp around the base)..
check video amplifier n sub section..
the colour diodes, transistors n resistances at the base..

for better supervision contact ur system admin/vendor....

if you have another spare monitor .. try to swap the monitor. If the same problem happens on the spare, then, most likely, the problem is your video card driver. Updating your video card to the latest version probably fixes the problem.

my monitor 943NW if power on the blue led light on normally,but no picture or blue colour display,please help me to solution,tanks.

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

Hello,
It may be due to the loose contact of the monitor signal cable
Contact the nearest Repairman

Let me know that your problem is solved and rate me as Fixya!

your problem is in blue color cathode circuit. as you say that it becomes ok tha5t means 1 cable wire is loose from computer to monitor. 2 crt base loose. 3 loose contact in blue video ckt. 4 signal processor cable to crt board connector loose.(blue wire)
