Error code DEAD PIXEL on the Samsung TV & Audio QN55LS03BAFXZA 55" Class The Frame QLED 4K Smart TV means: Dead or Stuck Pixel. Individual pixels are permanently dark (dead pixel — tiny black dot) or stuck on a single color (stuck pixel — bright red, green, or blue dot). On LCD/LED/QLED panels, dead pixels result from a failed TFT transistor. Samsung warranty requires a minimum threshold of defective pixels for a claim. Stuck pixels can sometimes be recovered by running pixel-cycling videos at full brightness for several hours. Dead pixels cannot be repaired without panel replacement.
