Sony BRAVIA A80J / A80K / A80L OLED: quick sheet

Covers: Sony BRAVIA XR A80J (2021), A80K (2022) and A80L (2023) WRGB OLED sets on Google TV.

Single sourceBrands: Sony6 components

Sony's mainstream OLED using a WRGB panel, 120 Hz with VRR (added by firmware on A80J), Google TV and the XR processor. No backlight: faults are power board, main board, panel (lines, burn-in) and software. Panel-refresh behavior is the most common 'it shut off by itself / it clicks at night' call.

Safety first

Power-board work only unplugged after discharge wait; live tests are caution work.
OLED panels crack easily; never press on the screen.

How it works

Each pixel emits its own light; the power board feeds the panel and main board directly. There are no LED strips to test.

After long viewing the set runs an automatic panel refresh while in standby. Sony states the process aborts if the TV is turned on, the cord is unplugged or the room is outside about 10-40 °C, and the TV then shows 'Panel refresh did not finish'; it restarts the next time the TV is switched off with the remote.

Same red-LED fault indication and restart ladder as other Sony Google TV sets.

Soundbar won't turn on with the TV, or TV remote won't control its volume (HDMI-CEC)

One-remote control depends on HDMI-CEC over the ARC/eARC cable. Disabled CEC, the wrong HDMI port, an optical connection, a poor cable or a TV update that switched settings off cause nearly all of these calls.

Soundbar audio cuts out, pops or drops with movies/Atmos (ARC/eARC)

Dropouts usually come from an unstable ARC/eARC handshake or a format the chain doesn't handle well. Work through cable, firmware, CEC conflicts and the TV's digital audio format; optical is a stable fallback without Atmos.

Projector won't turn on or shuts off (reading the indicator lights)

Projectors protect themselves: overheating, lamp at end of life, and lamp-cover interlocks all stop the light source. Read the indicators against the model's table, then fix airflow, lamp seating or lamp life.
