On the Screen Red pixels comes in the background

Please change the T-CON board, if it did not fix the problem, you may have a defective LCD Panel.

Cables loose connection, check with your technician

Try to remove the VGA cord and blow it. Insert it again and turn on your computer.

Could be whats known as dead pixels, this is tested be showing up a black or white screen. Microsoft paint or word will do. If an area always has dots then dead pixel. However if it doesn't constantly remain a dot then, some-thing else. Dead pixels come about due to age.
A technician will be able to diagnose your problem by performing white screen test.

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

The contrast of the monitor is very low. reset the monitor settings using the menu button in the monitor.

It seems that someone changed the desktop background color. point the mouse somewhere in the middle of the desktop, (away from any icons) and right click the mouse, a menu will appear with several options. The bottom one says properties. Click that. Once done another (more advanced) menu will appear with several tabs at the top. Click on the second to last tab, labled, "Appearance". Once in this tab. Toward the bottom right side of this screen you will see 2 buttons one atop another labled, "Effects", (on top), and, "Advanced", (below). Click the advanced button. A new window will pop up with the first option being desktop in a drop-down menu. To it's immediate right you will see "color 1" with a drop-down menu directly below it. That is where you will select the new background, (desktop) color. Once you have selected the new color, click OK, then apply on the remaining screen, then OK once the color is set.

Hi there
Firstly reinstall the graphics drivers, if its still the same there is a problem with the graphics card and you'll have to have it looked at.

Good luck and thanks for using Fixya!

Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.
