Manufacturer warranty (source market)
3years3Press releaseprtimes.jp/aRead 5 October 2026Maker technical table p4 three-year manufacturer warranty. Market: Japan. This does not establish burn-in terms in every market. Current Japanese body specs match US, while older launch chassis/power figures conflict and are not transferred. Canonical EU fiche separately states supplier minimum guarantee 2 years. The stored 3 years retains the explicitly documented Japan launch policy and does not promise 3 years in every market.11EU energy label (EPREL)eprel.ec.europa.eu/fiches/electronicdisplays/Fiche_2448020_EN.pdfRead 5 October 2026EU fiche gives minimum supplier guarantee 2 years, versus Japan launch policy 3 years.
