Samsung TV & Audio QN55LS03BAFXZA 55" Class The Frame QLED 4K Smart TV BACKLIGHT BLEED Error Fix: Backlight Bleeding / Clouding

Error code BACKLIGHT BLEED on the Samsung TV & Audio QN55LS03BAFXZA 55" Class The Frame QLED 4K Smart TV means: Backlight Bleeding / Clouding. Bright areas or uneven brightness at edges/corners during dark scenes. On edge-lit Samsung TVs (Crystal UHD), more noticeable. On full-array local dimming TVs (Q80C, QN90C), local dimming reduces bleeding but blooming (halos) can occur. Moderate bleed is within Samsung manufacturing tolerance. Reducing Backlight setting (Settings → Picture → Expert Settings → Backlight) minimizes appearance. Severe or worsening clouding can indicate failing LED strip, displaced diffuser sheet, or LED brightness shift.
