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.

A photo of a yellow car is pink


The discoloration indicates you are missing one of the three color bands (magenta, cyan and yellow). Likely the display cable from your computer to monitor has a slight break in one of the interior wires.

Slowly move the cable around near the connectors and observe the picture. If you see it change, replace the cable. You can get one from any computer store for about $10-$15.

It tuns green and when you turn on computer it turns yellow and then a light yellow and will not come on


Your monitor cable may be bad. This happens. Try a different cable.

If not, try a different monitor to ensure the computer is displaying. Also make sure everything is plugged in firmly (not HARSHly, just tight).

Also, try testing the monitor with a laptop. This will eliminate whether the monitor is shot.

Good luck!

Below you will find my recommendations for troubleshooting this issue:

1. Reseat the power cord and verify a good power source.

To reseat the power cord, follow the steps below:

1.1 Power down the system.
1.2 Unplug the power cord.
1.3 Wait approximately one minute.
1.4 Reseat the power cord.
1.5 Verify that the power cord is plugged directly into a known good power outlet.

2. Verify that the monitor is receiving power from a known good outlet and bypass any power strips.

To test the power outlet, perform the following steps:

2.1 Unplug the monitor power cable from the power outlet.
2.2 Plug in a different device, and verify that the device is operational.
2.3 If there is no power try another outlet. Remove any power strips and try plugging directly into the main power outlet.

3. Verify the monitor is powered on and the power button is engaged.

Ensure that the monitor is powered on and that the power button is fully engaged. To do so, check the power LED on the front of the monitor; it should be lit.

NOTE: There are two types of power switches:
A mechanical switch characterized by a long travel. You have to push it further and you will hear an audible click.
An electrical switch that has a short travel and almost no click.

A lit monitor LED can be any of the following:

* Green
* Blinking green
* Yellow
* Blinking yellow
* A combination, such as alternating green and yellow

Any of these states indicate the monitor is receiving power and that you should proceed.

4. Swap power cables.

To try a known good power cable on the monitor, follow the instructions below:

4.1 Turn off a working monitor.
4.2 Unplug the cable from the back of the working monitor, and unplug the cable from the wall.
4.3 Unplug the cable from the monitor in question.
4.4 Plug in the cable that came from the working monitor.

5. Run the monitor self test.

To run the monitor self test, perform the following steps:

5.1 Power off both the computer and the monitor.
5.2 Unplug the video cable from the computer or video card.
5.3 Reseat the power cord to the monitor, ensuring it is plugged into a known-good outlet.
5.4 Power on the monitor.

NOTE: The monitor self test will move around on some monitor models. If the monitor self test moves, allow it to move to the affected areas of the monitor to check for the problem described.

If the Self test failed, it's possible that the monitor is faulty. Contact dell to check if it's still under warranty so they can replace it.

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.

Check the video cable at both ends to make sure it is connected properly.
Move the cable around near the ends and chances are it will look normal. If so then you have a broken wire inside the video cable. A common thing and easy to get another cable.
