Sounds like overstressed video cable, at least that wire for BLUE signal, 'cause when image is yellow - the BLUE color is missing.
Open the monitor and ring coaxial wire in blue insulation.

It started to show preview (before you take a photo) with yellowish colors. the photo itself is goood, but when you are trying to take it all you see on the preview screen is unnatually yellow.. pelase...


I hope you did not drop the camera. The display can be damaged and it will hinder you. But it looks you still can make good pictures, so the camera part works.
If you want to screen to be normal again, I think you should visit a repairstore or your dealer.

Yellow screen


There are a variety of problems that can happen to the display monitor of an Acer laptop.
The most common problem is the screen fading or becoming too hard to see.
This can be corrected by adjusting the brightness levels.
Another common problem involves incorrect color, which can be resolved by adjusting the display color settings.
Yet another big problem is the display freezing or appearing jumpy, which can be resolved by updating the display driver.

Hold down the "Fn" key.
Tap the right-arrow key to brighten the display screen.

Tap the left-arrow key to darken the display screen.
Release the "Fn" key to save your display settings.
Color
Right-click on the desktop and click "Graphic Properties."
Adjust the screen resolution by clicking "Display Settings" and choosing a resolution setting from the drop-down menu.
Click "Apply" to check the resolution of the display.
Click "OK" to save the resolution settings.

Adjust the color of the screen by clicking "Color Correction" and moving the brightness or contrast slider to the right or left.
Click "Apply" to check the color resolution of the display.
Click "OK" to save the color settings.

Click "OK" to exit the Graphic Properties application.
Update the Display Driver
Right-click on the desktop. Click "Personalize," "Display Settings" and "Advanced Settings."
Click the "Intel Graphics" tab and choose "Monitor Properties."
Click "Driver."

Click "Update Driver" and choose "Search Automatically."
Click "Install" to install the updated monitor driver. After the driver has been installed, click "OK" to restart the laptop when prompted.
Yellow screen
Yellow tinting in monitors can be caused by either a software calibration issue, bad cables or a worn out display and backlight.
Before you assume that the issue is a hardware one, determine if there are software settings that affect the color or if the cables are working correctly.
After checking these items, and if the yellow tint only occurs on one monitor and you cannot eliminate it, the problem is a display hardware issue and it is less expensive to replace the monitor.

Unplug the power cord from the monitor and replace it with another one.
This is a standard power cord used in printers, monitors and desktop PCs so you can trade it for a cable from another device.
Turn on the PC and monitor to see if the yellow is still there.
Turn off the computer and monitor.
Replace the video cable with another VGA cable from another monitor.
Use one from another computer before going out to buy one.
Restart the computer to see if the yellow tint is gone.
Right click any area on the desktop and click "Properties" from the list of options that appears.
Choose "Display Settings," then "Advanced Settings."
Select "Monitor" and click the "Calibrate Color" button.
Wait to see if the yellow tint goes away.
Locate the temperature color settings on the monitor.
Adjust these to see if there is a change in the color.
A warm color setting will give the screen images more of a yellowish tint.
Click on the "Start" icon, then click "Control Panel" and "System and Security" and choose "Device Driver."
Locate the video driver and click "Update."
Select the option allowing Windows to connect to the Internet to find an updated driver.
Wait for the update to complete in a few minutes.
Expect the yellowing issue to disappear.
Connect the PC to another monitor to see if the same problem occurs.
If the yellow tint does not appear on the newly connected monitor, the problem is a bad backlight or display and the monitor should be replaced with a new one.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

12_27_2011_5_00_56_am.png

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

It is not a driver or video card problem. It is the monitor.

To be sure plug a full size desktop monitor into your laptops monitor jack. Every laptop has one. If the picture doesn't turn yellow that will confirm that your LCD is bad.

My monitor colour has changed to yellowish


The first thing to try is to make sure the video connections both at the monitor and the PC are secure. A number of color image problems are just a loose connection. Make sure you remove the connectors and then reseat them when you do this.

Projector displaying yellow tint in center of screen.


The yellow tint is probably coming from the lens. It could be that the glass is tempered or possibly just needs to be cleaned.
