LG 55QNED87 powers on with blank screen and abnormal startup, suspected power regulation/motherboard fault
An owner of the 55QNED87 describes a blank screen with abnormal startup behaviour and suspects a power-regulation or motherboard fault, and is seeking schematics to repair it.
What to check. A blank-screen-on-power-on failure on the 55QNED87 points to the power supply or motherboard rather than the panel; an owner facing this should expect a board-level repair or replacement, and should check warranty coverage before paying out of pocket.
LG 75QNED87A6B (2025 EU) sold as MiniLED FALD but engineering report finds edge-lit panel
An owner of the 2025 European 75QNED87A6B hired a professional engineer who concluded the set is edge-lit, not MiniLED FALD, despite LG advertising 2,040 local dimming zones; the owner filed with the Spanish Consumer Arbitration Board.
What to check. Before buying a QNED87 in the EU, verify the actual backlight architecture for your specific size/model year, since the advertised MiniLED spec may not match the delivered panel; a buyer who relies on the spec could pay a premium for an edge-lit panel and face a long dispute to get a replacement.
webOS 25 update on QNED87xxx breaks 4K HDR video output (audio only) in Kodi
An owner of the QNED87xxx series reports that after the 1.5 GB webOS 25 update, media playback regressed, including no video output for 4K HDR files in Kodi while Full HD HDR still works.
What to check. If you rely on local media playback (Plex/Emby/Kodi), the webOS 25 update is a known regression point on the QNED87 series; a buyer may want to hold off on the update or check for a patch (e.g. 33.22.85) before upgrading, since the fix can take longer to reach the cheaper QNED line than the OLEDs.
LG 43QNED87A6D cannot move or confirm channel numbers in the channel list
An owner of the 43QNED87A6D reports the channel list lacks move/confirm options, only lock/unlock/skip/restore, forcing repeated auto-retunes.
What to check. A minor but annoying software limitation on the 43QNED87A6D: you cannot reorder or confirm channel numbers, only skip/restore them, which matters if you rely on a custom channel order for free-to-air viewing.
LG QNED87B6A (TR) delivered with a gap between the bottom panel and screen, technician dismissed it
A Turkish buyer of the QNED87B6A reports a visible gap between the bottom panel and the screen from delivery, and that the LG technician dismissed it as not affecting the picture and offered no remedy.
What to check. In Turkey, a QNED87B6A can arrive with a panel-to-chassis gap that LG's service refuses to treat; a buyer should inspect the set at installation and push for a written report, since the seller's technician may decline to record the defect.
