    I have the problem with the monitor connected. It loads windows xp and then it goes completely white. First it was just a blank blue screen and now it's white. I can see the mouse cursor, but nothing else. No icons or sys tray, etc. Help!

That could be normal operation if it is not connected. Does it do the same when connected? If so, try another monitor. Does the computer power on normally otherwise?

My computer monitor screen display turns from white to yellow due to my daughter pressing the different buttons on the keyboard.

Kids always do this.

But let us see, does your monitor turn on and off correctly? And also please describe the problem competently to understand well and help you? Like which key pressing will change the color etc.,

Just in the mean time do check the cable connected at the back of the PC

My monitor keeps turning yellow constantly. How do i fix this problem?


-check the monitor cable (vga cable the one with blue connector) for broken pins
-if there are broken pins replace the cable
-if not try another monitor cable or try the monitor to another cable
-if the monitor still turns to yellow after trying another cable or connecting it to another computer to problem could be with the monitor or the vga card

Blue tint


Check the pins on the end of your vga cable from the monitor to make sure that the pins aren't bent.

If they are not bent then it could be a problem with the monitor itself. Try resetting the defaults on the monitor itself and see if the problem goes away if it does then your set.

If the problem still exists then try a different known good working monitor on the computer. If you still get the same problem then its a problem with the video card. If the problem goes away then you know its a problem with the monitor and would need to be replaced.

My Sony Moniter suddenly turned to a bright yellow


If the display looks normal other than being yellow, it's missing blue.

This may be because of a bad cable. Sometimes the wires inside break from flexing. Try wiggling the cable (as mikeslab suggested) at the end where it connects to the computer. Also check the plug for bent pins.

It's more likely the monitor has lost blue due to solder connections to the blue output transistor or transistor failure, or that the picture tube itself has gone bad and the blue gun has quit. Tube failure is pretty rare. I've seen many cases of bad connections and transistors, though.

If the cable and plug aren't the cause, you can have a service shop check the monitor and give a repair estimate. But if this is a 17- or 19-inch monitor, you might just want to replace it. New LCD's are $150 or less. To repair yours would be around half that cost already, possibly more depending on labor and parts costs.

Monitor only stays on a few seconds


You have a burned out Backlight Fluorescent Bulb.

Go to your monitor power settings and turn off Hibernation and other monitor power schemes.

If this problem persist, request for more technical assistance from the manufacturers website

My monitor turns yellow


Computer monitors get separate red, green and blue video signals from the computer, and if you lose the blue the result is a yellow picture. This can be caused by video card failure in the computer (very unlikely), a bad cable (fairly common), or trouble in the monitor (which is most likely what you have).

The usual problem with monitors is bad solder connections to the red, green and blue output devices. These are usually three separate transistors, but sometimes an integrated circuit that puts all three in one package is used. These outputs get pretty hot, and the heat can cause the connections on the circuit board to crack. Resoldering them usually fixes the trouble. (Sometimes the part actually fails, but bad connections are more common.)

The parts are normally in one of two places. Most commonly they are on the small circuit board you'll find right at the neck of the picture tube. Some monitors have them on the main circuit board. They may be mounted to metal heat sinks to help keep them cool. If you can identify them and resolder the connections, you'll probably get your normal picture back.
