What Does It Mean When a TV Shows a Blue, Green, or Red Tint?
If your television is displaying a strong hue of blue, green, or red, either across the entire screen or in patches, it’s usually a sign of a hardware malfunction or display calibration issue. It could be something as minor as a loose cable or as serious as a faulty T-Con board or damaged panel.
These tints are typically not resolved through standard settings and indicate a problem that requires professional intervention.
