Sony's A80L OLED is purchased for cinema-grade contrast and motion, so the panel is the key asset to protect. If the TV has a clean panel and the failure is clearly on the electronics side-power supply, main board, or HDMI issues-repair can be a strong value, particularly early in ownership.
If the set shows panel problems like persistent burn-in, large dead pixel clusters, or uniformity defects that are visible in normal content, replacement is usually more rational because OLED panel work is expensive and may not pencil out versus a new TV with warranty coverage. Also consider viewing habits: heavy static UI use increases burn-in risk over time.
When repair estimates approach the threshold, replacement typically offers lower risk and a fresh warranty, while preserving your time and reducing the chance of repeat failures.
