LG QNED80 / QNED85 (2022-2024): quick sheet
Covers: LG quantum-dot LCD QNED lines: QNED80 (2022 QNED80UQA, 2023 QNED80URA, 2024 QNED80T) and QNED85 (2022 QNED85UQA, 2024 QNED85TUA, e.g. 65QNED85TUA). Sizes about 50-86 in (98 in on some 2024 lines). The backlight changes by year: the 2022 QNED85 is mini-LED, the 2024 QNED85T is edge-lit (direct LED on 86/98 in).
Same series name, very different hardware by year. Before diagnosing, read the full model number: the 2022 QNED85UQA uses a mini-LED backlight with local dimming; the QNED80 and the 2024 QNED85T are mostly edge-lit. Panels are IPS-type (wide viewing angle, gray blacks). Platform is webOS.
Safety first
- Unplug and wait before opening.
- LED-driver and power-board live tests are caution work.
- Two-person panel handling.
How it works
Power board feeds the main board and the LED driver; the main board (webOS) feeds the panel timing electronics.
2022 QNED85: many small LEDs behind the panel in dimming zones. QNED80 and 2024 QNED85T: LEDs along the edge with a light guide, so a failed edge strip gives a dark side or a dim screen.
IPS-type panels show gray blacks and some glow in a dark room. That is normal and is not a backlight fault.
