Symptoms
- Image looks too green, pink, or blue overall
- Colors look washed out or oversaturated
- Skin tones look unnatural
- Tint changes with different sources
Likely causes
- CommonWrong picture mode or color temperature settingModes like 'vivid' or a warm/cool color temperature setting shift the overall tint.
- CommonCable-related color space mismatchAn HDMI source set to the wrong color format (e.g. RGB vs YCbCr) can shift colors.
- PossibleAging color wheel (DLP projectors)A failing color wheel can cause flashing or dominant color tints.
- Less commonFailing LCD panel or lamp aging unevenlyMore common in older 3-panel LCD projectors.
What to do
- Reset the picture mode to a neutral preset like 'Standard' or 'Movie' rather than 'Vivid' or 'Dynamic'.
- Adjust color temperature toward 'Normal' or 'Warm' and see if the tint corrects.
- On the source device, check the HDMI color format setting and try switching between RGB and YCbCr/YUV.
- Test a different source and cable to rule out the cable or device as the cause.
- Run any built-in color calibration or 'reset picture settings to default' option in the menu.
- If a DLP projector makes a rainbow flash or spins up before the tint appears, suspect the color wheel.
When to call a pro
If resetting settings and trying other sources doesn't fix a strong color cast, have a technician check the color wheel or panel.
