Standby LED dead, TV shuts off or won't start? We repair the power supply board of your LG OLED — €75 flat rate, 12-month warranty.
Do any of these symptoms match your LG OLED? Then the power supply is very likely the culprit.
The red standby LED dies and the TV only responds after you briefly unplug it from power — a classic power-supply failure sign.
The picture switches off without warning or the set won't boot at all — the voltage supply collapses.
The internal HDMI self-test reports NG although the panel is fine. Together with the standby-LED symptom this points to the power supply, not the mainboard.
The power supply board of your LG OLED only — diagnosis and replacement of the faulty component.
Mainboard and T-Con defects are explicitly not part of this repair. If the TV stays on with the standby LED but shows no picture, the mainboard is usually at fault.
C1, C2 and CX OLED series — e.g. OLED65C17LB / LG65C17LB and identical 48"/55"/65"/77" models.
