White should be neutral, but many TVs display whites with a **blue tint** (cool) or **yellow tint** (warm). This is almost always a **color temperature setting** issue. “Cool” adds blue to make whites look brighter (common in store demo modes). “Warm” adds red/yellow to match cinematic standards (D65 white point). However, if the tint appears only on part of the screen, it could be a **backlight aging** issue (yellowing LEDs) or a **polarizer film** degrading. On OLEDs, uneven aging of the blue subpixels can cause a yellow tint in whites after years of use.
**Fix:**
- Go to Picture → Color Temperature or White Balance.
- Choose “Warm 1” or “Warm 2” for accurate white—but give your eyes a week to adjust.
- If using “Cool” and whites look blue, that’s normal for that mode.
- For actual hardware yellowing: no fix except panel replacement.
- Some TVs have **2-point or 20-point white balance** controls—leave them alone unless calibrated.
- Reset picture settings to defaults.
If whites look yellow/green in HDR, the TV may incorrectly map white point. For professional white balance adjustment: https://alhea.in/lg-service-centre-in-hyderabad
