Patchy color problem

This is a probable sign the TV or monitor is dying, though in some cases it can be a bad cable, or bad video card (if this is a PC monitor).

Reinstall browser. Is that only in browser or everywhere ? Consider reinstalling Windows again

Most of the cases fuser assembly or supplies are causes of ghost image. If image is not properly transferring on media causes transfer roller or ETB.
Do this small exercise: Give print command, wait till paper grabs, once paper entered in cartridge area, power it off, open top & front cover, remove paper and see the print quality.Observed any ghost image what you observed? No ghost image? then problem with fuser assembly..

1.Remove fuser assembly, check any toner particles deposited on surface of fuser transfer roller or heater roller.. if found clean carefully with good cotton cloth while fuser having certain temperature,pl avoid metal & sharp objects to clean..
2. Clean paper path roller(You can observe the rollers to push the paper to reach the destination)
I hope this exercise will resolves the issue..

Sounds like it's either ghosting, or image persistance.

Ghosting on LCD monitors is usually caused by interference via the monitor cable. Try moving your monitor cable so that it doesn't pass near any other cables or electronic devices. If that helps, then position the cable away from the others perminantly or replace the cable with a "shielded" monitor cable.

Image persistance on an LCD can be caused by leaving it on with the same image for a very long time. The pixels don't exactly "burn-in" like on the old CRT monitors, but over time, they can develop a memory that causes them to change color slowly or incompletely. Prevention is best (turn the monitor off when not in use, or use a rotating screen saver.) But if it is already a problem, you do have a few options. You can turn it off for a long time, run a rotating screen saver for a long time, or display a solid white screen for a while. Another technique is to create a slideshow in the Windows screensaver with a solid white image and a solid black image (create them in MS Paint and save them where you can find them later.) Let it alternate between the white and black screens for a while and check to see improvements.

Good luck!

tienes que cambiar la memoria que tiene problemas (DDR 1 or DDR 2). y luego enciendes el ordenador

Usually, LCD monitor ghosting appears when the cable isn't tight, the cable is faulty, or low quality. The cable should be less than 8-10 feet long. Try using a different monitor cable (they're mostly interchangable) and see if the problem goes away. I'd put my money on the cable or a loose cable connection.

Although it is possible that your monitor is defect, you should first run a monitor test to see if you just need to adjust some of the settings. Go to this webpage and just follow the instructions.
The test are done best in full screen mode (F11 in most browsers).

Do you have any sources of magnetic fields next to the monitor (speakers, halogen lights, sometimes even a cordless phone can cause distortion).

If you can, connect this monitor to another computer and see if the problem persists. This way you eliminate any hardware related issues (cable, video card).

If you have any more questions (also regarding the results) come back here and leave a comment. I will check back and see what else we can do.

Please rate this response thanks.

Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

No, it is not the electricity in your house, I had the same problem. Send it back to Samsung and get a new one. I have had to send my monitor back 4 times!
