Re: Color adjustment for CM 811U

Benimur, To clarify we are the tech people who changed the tube. Normally we hook a sencore color generator to the monitor and use that to adjust the color. This monitor will not allow you to do this from what we can gather without some type of external box that plugs into a serial type connector inside the monitor. We have a similar setup that we use for some viewsonic monitors. Hitachi told us that this exists but would not provide any further info on it.

Re: Color adjustment for CM 811U

Hi, if you are referring to the replacement of the picture tube, then yes, the color will have to be adjusted. However this should have been done by the tech personnel who did the replacment with a color bar generator and alignment tools. You can also try pressing the degauss button on the monitor to see if the color balances back. Hope this be of some help. Good luck

My monitor does not have any red color to it is there a way to adj. color inside of monitor. thank you

It is very dangerous to work on tv's or monitors without the proper training. They hold voltage even after they are turned off and unplugged, enough to seriously injure someone. There are however adjustments that can be made once you crack open the casing, but if it has already lost color, it will only continue to lose it if you can ever get it set back right again. You best option would be to acquire another monitor. If you want to try it anyway, there are screws in the back of the metal chassis that adjust color, hue, brightness, and shape, that can be adjusted with a small screwdriver.

Is it possible to change the color temperature on Studioworks 560N?

Much better if you change the color control on your PC. Or your desktop right click properties, On the Display properties click settings, under the setting select Advanced. Look for your videocard software control. It will let you adjust the Gamma, Contrast, Color control of your display properties.

Do you have a CRT monitor?
Have you tried to adjust the color on the monitor?
How is it connected to your computer?
It sound like one of the guns on you monitor died. But there is some testing you should do first.
If it is a CRT monitor and it is connect your computer properly. First thing to do would be to replace the cable and or try a different monitor that you know works.
To confirm try adjusting the color. If that does not work, if it more purplish it is the green gun, if it is orangish it is the Blue gun. That would be cause by a failed gun or driver.
If the gun is gone it is best to get a new one. It will save you money in the long run.

Thank you...

You can adjust the colors manually on the Chroma circuit Board at the back of the CRT. Or check for any cold solder and do drysoldering. Cheers

The monitor hjas lost its original colour,It potrays images that are a bit red and yellow.Its a Compaq V570

It's probably not a matter for adjustment, it's probably in need of electrical troubleshooting to find and replace defective components. It may be the CRT itself. One way they often fail is to show or lose one particular color more than another. These days a common 15" CRT monitor is probably not economical to repair by a brick-and-mortar service shop.
